How to convert feet to meters

1 foot equals 0.3048 meters:

1 foot = 0.3048 m

The distance d in meters (m) is equal to the distance d in feet (ft) times 0.3048:

d(m) = d(ft) × 0.3048

example

Convert 20 feet to meters:

d (m) = 20 feet × 0.3048 = 6.096 m

How many feet in a meter

One meter equals 3.2808 feet:

1m = 1m / (0.3048m/ft) = 3.2808ft

How many meters in a foot

One foot equals 0.3048 meters:

1 foot = 0.3048 × 1 foot = 0.3048 m

How to convert 10 feet to meters

Multiply 10 feet by 0.3048 to get meters:

10 feet = 0.3048 × 10 feet = 3.048 m

Underwater diving to a depth beyond the norm accepted by the associated community

Diver using a rebreather with open circuit rescue cylinders returning from a 180m dive

Deep diving is underwater diving to a depth beyond the norm accepted by the associated community. In some cases this is a mandatory limit set by an agency, while in others it is associated with a level of certification or training and may vary depending on whether the diving is recreational, technical or commercial. Nitrogen narcosis becomes a hazard below 30 meters (98 ft), and hypoxic breathing gas is required below 60 meters (200 ft) to reduce the risk of oxygen toxicity.

For some recreational diving agencies, “deep diving” or “deep diving” may be a certification awarded to divers trained to dive to a specific depth range, generally deeper than 30 meters (98 feet). However, the Professional Association of Diving Instructors (PADI) defines anything from 18 to 30 meters (60 to 100 feet) as “deep diving” in the context of recreational diving (other diving organizations vary) and considers deep diving to be a form of technical diving.[1] In technical diving, a depth below about 60 meters (200 feet) where hypoxic breathing gas becomes necessary to avoid oxygen toxicity may be considered a deep dive. In professional diving, a depth that requires special equipment, procedures, or advanced training may be considered a deep dive.

Deep diving can mean something else in the commercial diving field. For example, early experiments conducted by Comex S.A. (Compagnie maritime d’expertises) with Hydrox and Trimix, depths far greater than any technical recreational diving. An example is the Comex Janus IV open sea dive to 501 meters (1,644 ft) in 1977. [2] [3] The open sea diving depth record was set in 1988 by a team of Comex divers working as part of the Hydra -8 program conducted pipeline liaison exercises in the Mediterranean Sea at a depth of 534 meters (1,752 feet).[4] These divers had to breathe special gas mixtures because they were exposed to very high ambient pressures (more than 50 times atmospheric pressure).

An atmospheric wet suit allows for very deep dives of up to 610 meters (2,000 feet). These suits can withstand the pressure at great depths, allowing the diver to stay at normal atmospheric pressure. This eliminates the problems associated with breathing high pressure gases.

Depth ranges in underwater diving[ edit ]

The surface of the body of water is assumed to be at or near sea level and subject to atmospheric pressure.

Not included are the different areas of freediving – without breathing during a dive.

Special problems related to deep dives

Deep diving presents more danger and risk than simple open water diving.[19] Nitrogen narcosis, the “narks” or “deep rush”, begins with feelings of euphoria and overconfidence, but then leads to feelings of numbness and memory disorders, similar to alcohol poisoning. Decompression sickness or the “bends” can occur when a diver ascends too quickly when excess inert gas leaves a solution in the blood and tissues and forms bubbles. These blisters create mechanical and biochemical effects that lead to the disease. Symptom onset depends on the severity of tissue gas exposure and may develop during ascent in severe cases, but is often delayed until after reaching the surface. Bone degeneration (dysbaric osteonecrosis) is caused by blisters that form in the bones; most commonly the upper arm and thighs. Deep diving carries a much greater hazard of all of these, and carries the added risk of oxygen poisoning, which can lead to an underwater spasm. Very deep diving with a helium-oxygen mixture (heliox) carries the risk of high pressure nervous syndrome. A good level of physical fitness is required to cope with the physical and physiological challenges of deep diving.[20]

With normal diving equipment, breathing gas consumption is proportional to the ambient pressure – so at 50 meters (160 feet) a diver breathes six times as much at a pressure of six bar as on the surface (1 bar). Heavy physical exertion makes the diver breathe even more gas, and the gas becomes denser, requiring increased effort to breathe with depth, leading to an increased risk of hypercapnia — an excess of carbon dioxide in the blood. The need for decompression stops increases with depth. A diver at 6 meters (20 feet) can dive for many hours without making decompression stops. At depths greater than 40 meters (130 feet), a diver may have only a few minutes at the deepest point of the dive before decompression stops are required. In an emergency, the diver cannot immediately ascend to the surface without risking decompression sickness. All of these considerations result in the amount of breathing gas required in deep diving being much greater than in shallow water diving. The diver must be disciplined in planning and executing dives to minimize these additional risks.

Many of these problems are avoided through the use of surface-supplied breathing gas, closed diving bells, and saturation diving at the expense of logistical complexity, reduced diver maneuverability, and greater cost.

Dealing with depth[edit]

Both the equipment and procedures can be adapted to handle deeper problems. Usually both are combined because the procedures need to be adapted to the equipment and in some cases the equipment is needed to facilitate the procedures.

Gear adjustments for deeper diving

The equipment used for deep diving depends on both the depth and the type of diving. Diving is limited to equipment that can be worn by the diver or easily deployed by the dive team, while surface-supplied diving equipment can be more extensive and much of it remains above the water where it is operated by the support team. citation required]

Procedural adjustments for deeper diving

Procedural adaptations for deep diving can be classified as those procedures for the operation of specialized equipment and those directly related to the problems caused by exposure to high ambient pressures.

The primary technique for dealing with physiological breathing problems at high ambient pressures associated with deep diving is decompression. This is necessary to prevent the formation of inert gas bubbles in the diver’s body tissues, which can cause serious injury. Decompression procedures have been derived for a wide range of pressure loads using a wide range of gas mixtures. These essentially involve a slow and controlled depressurization during the ascent through a limited ascent rate and decompression stops, so that the inert gases dissolved in the diver’s tissue can be safely eliminated during normal breathing.

Gas management procedures are necessary to ensure that the diver has access to appropriate and sufficient breathing gas at all times during the dive, both for the planned dive profile and for any reasonably foreseeable eventuality. Diving gas management is logistically more complex than surface supply, as the diver must either carry all the gas or follow a route where previously arranged gas supply depots have been established (stepped cylinders). or must rely on a team of support divers to deliver supplemental gas at pre-arranged signals or points on the planned dive. On very deep dives, or on occasions where long decompression times are planned, it is common for support divers to meet the main team at decompression stops to check if they need assistance, and these support divers often carry extra gas supplies just in case the emergency. The use of rebreathers can reduce the bulk of gas supplies for long and deep dives, at the expense of more complex equipment with more potential failure modes, requiring more complex procedures and a heavier load of procedural tasks.

Surface-supported diving distributes the task load between the divers and the support team, who remain in the relative safety and comfort of the surface control position. The gas supply is limited only by what is available at the control position and the diver need only carry sufficient rescue capacity to reach the nearest safe location, which may be a diving bell or barrier dive boat.

Saturation diving is a procedure used to reduce the risky decompression experienced by a diver during a long series of deep underwater exposures. By keeping the diver under high pressure throughout the work and only decompressing underwater at the end of several days to weeks, a single decompression can be performed more slowly without increasing the overall time for work. During the saturation period, the diver lives in a pressurized environment at the surface and is transported under pressure in a closed diving bell to the underwater worksite.

Ultra deep diving [ edit ]

Among technical divers, there are divers who participate in ultra-deep diving when diving below 200 meters (660 feet). This practice requires a high level of training, experience, discipline, fitness and surface support. Only thirty-five people are known to have recreationally dived below 240 meters (790 feet) using self-contained breathing apparatus.[21][22][nb 4][nb 5] The holy grail of deep diving was the 300 -m mark first reached by John Bennett in 2001 and has only been reached seven times since.

The difficulties of ultra-deep diving are numerous. Although commercial and military divers often operate at these depths or even deeper, they are supplied from the surface. All of the complexities of ultra-deep diving are compounded by the requirement for the diver to carry (or supply) their own gas underwater. These lead to rapid descents and “jump jumps”. Not surprisingly, this has led to extremely high mortality rates among those who practice ultra-deep diving. Notable ultra deep diving fatalities include Sheck Exley, John Bennett, Dave Shaw and Guy Garman. Mark Ellyatt, Don Shirley and Pascal Bernabé were involved in serious incidents and were lucky to survive their dives. Despite the extremely high mortality rate, the Guinness Book of World Records still holds a record for scuba diving (although it has stopped recording the record for deep air diving in deference to the mortality rate). Significant health problems are reported among those who survive. Mark Ellyatt is said to have suffered permanent lung damage; Pascal Bernabé (who was injured during his dive when a light imploded on his mask[23]) and Nuno Gomes reported short to medium term hearing loss.[24]

Some of the serious problems faced by divers performing ultra-deep diving with self-contained breathing apparatus include:

High Pressure Nervous Syndrome (HPNS) HPNS, produced by breathing helium under extreme pressure, causes tremors, myoclonic jerks, somnolence, EEG changes,[25] visual disturbances, nausea, dizziness, and decreased mental capacity. Symptoms of HPNS are exacerbated by rapid compression, a trait common to ultra-deep “bounce” dives. Decompression Algorithm There are no reliable decompression algorithms tested for such depths assuming immediate surfacing. Almost all decompression methods for such depths are based on saturation and calculate ascent times in days rather than hours. Accordingly, ultra-deep dives are almost always a partially experimental basis.

In addition, “normal” risks such as gas reserves, hypothermia, dehydration, and oxygen toxicity are compounded by extreme depth and exposure. Much engineering equipment is simply not designed to withstand the necessarily greater stresses at depth, and reports of key equipment (including dive pressure gauges) imploding are not uncommon.

Ultra Deep Air [ edit ]

A serious risk in ultra-deep air diving is deep-water blackout, or depth blackout, a loss of consciousness at depths below 50 m with no clear primary cause, associated with nitrogen narcosis, a neurological impairment with anesthetic effects caused by high partial pressures of nitrogen dissolved in nervous tissue and possibly acute oxygen toxicity.[48] The term is not currently widely used, as a more specific term is preferred where the actual cause of the power outage is known. The depth at which a deep-water blackout occurs is highly variable and unpredictable.[49] Prior to the widespread availability of trimix, attempts were made to set world record depths using air. The extreme risk of anesthesia and oxygen toxicity among the divers contributed to a high mortality rate in the record attempts. In his book Deep Diving, Bret Gilliam chronicles the various disastrous attempts at records and the fewer successes.[50] Of the comparatively few who have survived extremely deep air dives:

1947 – Frédéric Dumas, a colleague of Jacques Cousteau, dived 94 m (307 ft) in air [50]

1947 – Maurice Fargues, another of Jacques Cousteau’s colleagues, dove to 117 meters (384 ft) in air but died after losing consciousness at the depth.

1957 – Eduard Admetlla i Lázaro descended to 100 meters in the air. [51]

1959 – Ennio Falco reported reaching a depth of about 435 feet (133 m) on the air, but had no way of recording it [50]

1965 – Tom Mount and Frank Martz dive on air to a depth of 360 fsw [50]

1967 – Hal Watts and AJ Muns air dive to a depth of 120 m (390 ft). [50]

1968 – Neil Watson and John Gruener descend to 133 m (437 ft) in the Bahamas. Watson reported that he had absolutely no memory of what happened at the end of the descent due to anesthesia. [50]

1971 – Sheck Exley dove near the island of Andros in the Bahamas on December 11 to 142 meters (466 ft) in the air. Exley was only scheduled to go down to 91 meters (299 ft) in his capacity as a safety diver (although he had practiced several dives to 120 meters (390 ft) in preparation) but descended to check on the dive team after they failed on schedule to return. Exley almost made it to the divers but had to turn back due to heavy anesthesia and nearly fainting. [52]

1990 – Bret Gilliam airborne dove to a depth of 452 fsw. Unusually, Gilliam remained largely functional at depth, able to solve basic math problems and answer simple questions his crew had previously written on a blackboard. [50]

1993 – Bret Gilliam extended his own world record to 475 fsw and again reported no ill effects from anesthesia or oxygen poisoning. [50]

1994 – Dan Manion set the current record for a deep dive on air at 509 fsw. Manion reported that he was almost completely incapacitated by anesthesia and has no memory of the time at the Deep.

In deference to the high mortality rate, the Guinness Book of World Records stopped publishing records of deep air diving in mid-2005.

Fatalities in depth record attempts

Maurice Fargues died in 1947 in an experiment to see how deep a diver could go. He reached 120 m before returning no line signals. [11]

Hope Root died in December 1953 trying to break the deep diving record of 330 feet; He was last seen passing 625 feet. [53]

Archie Forfar and Anne Gunderson died off the coast of Andros Island, Bahamas on December 11, 1971 while attempting to dive to 480 feet, which would have been the world record at the time. Her third team member, Jim Lockwood, survived only because he used a safety weight that fell when he lost consciousness, causing him to begin an uncontrolled ascent before being intercepted by a safety diver at a depth of about 300 feet . As mentioned above, Sheck Exley, acting as another safety diver at 300ft, inadvertently managed to set the depth record when descending to Forfar and Gunderson, both of whom were still alive at 480ft despite being completely incapacitated by anesthesia were . Exley had to give up his attempt at about 465 feet when the anesthetic almost overwhelmed him too. Forfar and Gunderson’s bodies were never recovered. [citation required]

Sheck Exley died in 1994 trying to reach the bottom of Zacatón in a dive that would have extended his (then) own world record for deep diving. [54]

Dave Shaw died in 2005 attempting the deepest physical recovery and deepest dive ever using a rebreather. [55] [56]

Brigitte Lenoir, who planned to make the deepest dive ever made by a woman, died in Dahab, Egypt, in 2010 during a training dive. [57]

Guy Garman died on August 15, 2015 in an unsuccessful attempt to dive to 1,200 feet (370 m). [58] [59] The Virgin Island Police Department confirmed that the body of Dr. Guy Garman was recovered on August 18, 2015. [60]

The Virgin Island Police Department confirmed that the body of Dr. Guy Garman was recovered on August 18, 2015. Theodora Balabanova died on September 27, 2017 in Toroneos Bay, Greece while attempting to break the women’s deep diving record. She did not complete the decompression stops and surfaced early. [61]

Waclaw Lejko died on September 27, 2017 while attempting to 275 m / 902 ft in Lake Garda. His body was recovered by ROV at 230 m / 754 ft. [61]

Adam Krzysztof Pawlik died on October 18, 2018 while attempting a 316m dive in Lake Garda. His body was at 284 meters. [62]

Sebastian Marczewski, attempting a 333m dive in Lake Garda, reached the target depth of 333m, but his tanks became entangled in his ascent line at 150m. He died on July 6, 2019.[63]

Sometimes it can be useful to convert meters to other units of measurement. This can be done using unit conversion factors used in a method called dimensional analysis. This method is useful for converting units in all areas of science. The units are arranged so that the old units are removed and the new units are applied to the number.

meters on foot

One meter equals 3.2 feet. So to convert meters to feet, we multiply the number of meters by 3.2. Let’s look at an example. Suppose you measured the length of a room as 6 meters. But you want to hide this at your feet. You can start doing a conversion when you know that one meter equals 3.2 feet.

6 meters * (3.2 feet / 1 meter) = 19.2 meters

So the room you measured is 6 meters or 19.2 feet long.

What is meant by meters in feet?

In mathematics, meter to feet is the conversion of the measurement of length in meters to the equivalent measure in feet. Both meters and feet are the unit of measure used to define length. Meter is the SI unit used to measure length and distance. It is generally notated with the letter “m”. The feet or foot is the measurement system commonly used in the United States and is represented by the notation “ft”.

Conversion from meters to feet

One meter is approximately 3.28084 feet.

(i.e.) 1 meter = 3.280839895 feet

To convert meters to feet, multiply the given meter value by 3.28084 feet.

For example, 5 meters is converted to feet as follows:

We know that to convert 5 meters to feet, multiply 5 by 3.28084.

(i.e.) 5 meters = 5 × 3.28084 feet

5 meters = 16.4042 feet

So 5 meters in feet equals approximately 16.4042 feet.

Conversion from feet to meters:

Similarly, the conversion from feet to meters is given below:

We know that 1 m is approximately 3.28084 ft

So, 1 foot = 1/3.28084

1 foot = 0.3048 m

Therefore, one foot is approximately 0.3048 meters.

For example, we know that 10 meters in feet is 32.8083 feet.

If we multiply 32.8083 ft by 0.3048 m, we get the conversion from feet to meters.

Now let’s try the same example.

32.8083 feet = 32.8083 x 0.3048 m

32.8083 feet = 10m

Therefore 10 meters in feet is 32.8083 feet or vice versa.

Example of converting meters to feet

They have a roll of tape and the label says there is 15 meters of tape on the roll. How many meters of tape are on the roll? Multiply 15 meters by 3.28084 and you get 49.2126 feet of tape.

Measuring distances with a ruler, tape measure, or laser measure is easy. You can also easily convert from standard imperial to metric units and back. For example, your meter tells you that 3 meters is approximately 3.28084 yards, 9.84252 feet and 118.11 inches.

Ever wanted to measure the length of something without a ruler or tape measure? While this skill can take years to master, the next best thing you can do is compare distances to objects.

In this guide, I’ll show you 9 things that are 10 feet long or close.

3 large movie posters

If you’ve ever been to a movie theater lately, you’ve probably seen all sorts of movie posters hanging on the walls. These posters are designed to let you know which films are coming to theaters soon or which films are currently showing.

Large movie posters are generally 36 inches high, which is 3 feet. So to get 3 meters you would need to collect 3 big movie posters and place them on top of each other. You could also use medium sized movie posters (24 inches high) but you would need 5 of them to get to 3 meters.

intelligent car

There are many reasons why you should consider owning a smart car. First, they use electricity to run instead of gasoline, making them much less harmful to our environment. Also, smart cars don’t take up that much space on the road due to their small size. So if everyone switched to smart cars, the roads would be less congested.

Today you can find smart cars that measure about 101.6 inches from bumper to bumper. That’s only about a foot short of the 3 meter mark. You can compensate for the missing foot by attaching a foot-length Subway sandwich to the end of a bumper.

2 pool cues

While billiard cues come in all sorts of lengths, the average player will typically use a cue that is around 57 or 58 inches long, depending on how many pieces it contains. So if you take 2 average sized billiard cues and put them together they would give you an overall length of about 114 to 116 inches which is pretty close to 3 meters.

The length of the pool cue depends on the type of cue used. For example, jump cues can be around 41 inches long (about 3 to get to 3 meters), while the longest pool cue ever would have to be cut in half to get close to 3 meters.

7 concrete blocks

Concrete blocks are super versatile building materials that you can use for all kinds of backyard projects. They usually measure between 4×8×8 to 12×8×16 inches, but those are the nominal (marketed) dimensions. Actual dimensions may vary by a few sixteenths of an inch from the nominal dimensions.

Anyway, if you placed 7 16 inch long concrete blocks side by side lengthwise they would add up to about 3 feet. To measure 3 meters high you would need to stack 15 concrete blocks without mortar.

3 meter charging cable

One of the easiest ways to measure an object that is X meters long is to take objects that are 1 meter long and multiply them by the number of meters you want to measure. If you can’t gauge the height of a countertop or don’t have $6 bills in your wallet, you can use your USB charging cable instead.

USB charging cables are generally sold in 1 meter units, so 3 of these would make 3 meters. There are even 3 meter USB cables to keep your phone charged while you use it in bed.

2 rolls sod

Sods are basically just patches of dirt and grass. People buy sod rolls to cover large grassless patches in their yards and give them a more uniform look. Sod rolls come in a variety of lengths and widths, but on average they measure about 5 feet in diameter.

5 feet is the same as 152 centimeters, so if you multiply it by 2 you would get extremely close to 300 centimeters or 3 meters. You can also pick up turf tiles, some of which are 24 inches long. So, 5 of these placed next to each other would equal a few inches over 3 meters.

Christmas tree

Since 3 meters is so close to 10 feet, you could find any object roughly 10 feet long or tall and use that as a reference. You can check out my guide to 9 things that are 10 feet long and pick any item you like.

If you’re short on time, a large Christmas tree will measure 10 feet or just under 3.05 meters tall. So if you celebrated Christmas with a big tree last year, you should get a feel for its height so you can imagine what 3 meters looks like.

table tennis table

Table tennis has a number of health benefits including but not limited to improving coordination and reflexes. While it’s not a full-fledged sport, it’s certainly a popular one, at least here in the United States. In fact, your office break room could have a ping pong ball for employees to relax a bit.

Depending on the size of the table tennis table, it can be around 2.74 meters long. That’s about 10 inches short of the 3-meter distance we want to measure by eye. You can use any of these 8 common things that are 10 inches long to make up for the missing spacing.

1.5 king or queen mattresses

Did you know that there is a difference between king and queen size mattresses in the US and UK? In the US, these mattresses are 80 inches long. In the UK they are 200 centimeters (78.74 in).

So with 1.5 king or queen size mattresses you are either getting very close or exactly 3 meters.

Facts about meters (m)

The meter or meter (US) is a measure of length. It is the fundamental unit of length in the metric system and the International System of Units (SI) used for general and scientific purposes worldwide. The symbol for meter is m. Historically, the meter was defined by the French Academy of Sciences as 1/10,000,000 of the distance from the equator to the North Pole through Paris. It is now defined by the International Bureau of Weights and Measures as the distance traveled by light in absolute vacuum in 1/299,792,458 of a second. This roughly corresponds to the distance from the ground to the hipbone of an average barefoot man. See all meter conversions here.
