The standard atmosphere (symbol: atm) is a unit of pressure defined as 101325 Pa. It is sometimes used as a reference pressure or standard pressure. It is approximately equal to Earth’s average atmospheric pressure at sea level[citation needed].

History [ edit ]

The standard atmosphere was originally defined as the pressure exerted by 760 mm of mercury at 0 °C and standard gravity (g n = 9.80665 m/s2).[1] It was used as a reference condition for physical and chemical properties, and was implicit in the definition of the Celsius temperature scale, which defined 100 °C as the boiling point of water at this pressure. In 1954, the 10th General Conference on Weights and Measures (CGPM) adopted standard atmosphere for general use and affirmed its definition of being precisely equal to 1013250 dynes per square centimetre (101325 Pa).[2] This defined both temperature and pressure independent of the properties of particular substance. In addition, the CGPM noted that there had been some misapprehension that it “led some physicists to believe that this definition of the standard atmosphere was valid only for accurate work in thermometry.”[2]

In chemistry and in various industries, the reference pressure referred to in standard temperature and pressure (STP) was commonly 1 atm (101.325 kPa) but standards have since diverged; in 1982, the International Union of Pure and Applied Chemistry (IUPAC) recommended that for the purposes of specifying the physical properties of substances, standard pressure should be precisely 100 kPa (1 bar).[3]

The ata unit is used in place of atm to indicate the total pressure of the system, compared to a vacuum.[4] For example, underwater pressure of 3 ata would mean that this pressure includes 1 atm of air pressure and thus 2 atm due to the water.

How to Convert Atmospheres to Pascals

To convert an atmosphere measurement to a pascal measurement, multiply the pressure by the conversion ratio.

Since one atmosphere is equal to 101,325 pascals, you can use this simple formula to convert:

pascals = atmospheres × 101,325

The pressure in pascals is equal to the atmospheres multiplied by 101,325.

For example, here’s how to convert 5 atmospheres to pascals using the formula above. 5 atm = (5 × 101,325) = 506,625 Pa here’s how to convert 5 atmospheres to pascals using the formula above.

Atmospheres and pascals are both units used to measure pressure. Keep reading to learn more about each unit of measure.

What is a pascal as a unit of pressure or stress?

What is a pascal? The pascal (Pa) is the unit of pressure or stress in the International System of Units (SI). It is named after the scientist and mathematician Blaise Pascal. One pascal is equivalent to 1 newton (N) of force applied over an area of 1 square meter (m2). The pascal is also used to measure stress, specifically tectonic stress in the Earth’s plates. For most engineering problems, the unit is too small to properly represent pressure or stress, which is why it is often expressed in its multiples, like the kilopascal (kPa), megapascal (MPa), millibar (100 Pa), etc.

Understanding pascal Pressure is the force applied over an area. In the meter-kilogram-second system, it is expressed in pascals. Specifically, a pascal measures the pressure applied by 1 N of force applied on an area of 1 m2 at a right angle. SI accepted it as the standard unit of pressure in 1971 and named it after Blaise Pascal. In mathematical terms, pressure can be expressed as the following: Pressure (P) = Force (F) / Area (A) If F is measured in newtons and A in square meters, a pascal can be expressed as the following: 1 Pa = 1 N / m2 = 1 N x m-2 or 1 N per m2 Reduced to base units in SI, 1 Pa is 1 kilogram per m/s2 — that is, 1 Pa = 1 kg x m-1 x s-2. Larger pascal units are expressed as follows: 1 kPa = 1,000 Pa = 10 3 N/m 2

N/m 1 bar = 10 5 Pa = 10 5 N/m 2

Pa = 10 N/m 1 MPa = 106 Pa = 106 N/m2 Blaise Pascal is also the namesake behind the well-known Pascal’s law, which is used to develop hydraulic systems. A principle in fluid mechanics, it states that a change in pressure in a fluid creates the same change everywhere within the body of the fluid.

Measuring pressure in pascal Here is an example of how pressure is measured in pascal. Consider an object being pushed against a wall with a force of 400 N. The surface area that the object makes with the wall is 0.0008 m2. Using this data, pressure can be calculated as follows: P = 400/0.0008 = 500,000 Pa or 500 kPa Since pressure and surface area are inversely related, an object of a smaller surface area generates a higher pressure than a larger object. This explains why a small pin or screw can penetrate a concrete wall when only a small or moderate force is applied, but a human thumb fails to do the same even if the force applied is larger.

Young’s modulus and pascals Young’s modulus is a mathematical constant that describes the elasticity of solid materials. When compression or tension is applied to the modulus, the material is either elastic or inelastic — or some version between these properties. If Young’s modulus is high, the material is less elastic and vice versa. The pascal is used to measure this value and to understand if a material is elastic or not and to what extent.

Pascal versus PSI In some countries, such as the U.S., pressure is expressed as pounds per square inch (PSI). But, in most other countries that use metric and SI measurements, the pascal is used to measure pressure. Unlike units such as PSI where the pressure value may vary, the pressure value represented by 1 Pa remains unchanged, regardless of where it is used. Additionally, the unit is independent of other factors, such as ambient temperature, media density or local gravity.

Uses of pascal A pascal is useful for ultralow gas pressure applications, such as ventilation systems where pressure differences need to be measured. For measuring midrange pressures, higher pascal units, such as kilopascal, megapascal and hectopascal (hPa) are used. Geophysicists use the unit to study tectonic stresses acting on the Earth’s plates. Material scientists use it to measure the elasticity, stiffness, tensile strength and compressive strengths of different materials. Meteorologists also use the unit to measure air pressure, which is usually expressed in hectopascal.

Common conversions among different pressure units Pascal is not the only unit of pressure. It is useful to understand some common conversions among these different units: 1 Pa = 0.00001 bar or 1 bar = 100,000 Pa

1 Pa = 0.0000098692316931 atmosphere (standard) and 1 atm = 101.325 kPa

1 Pa = 0.00014503773801 PSI or 1 PSI = 6,895 Pa
