Significant Figures Rules

Significant Figures Rules

Calculating the number of significant figures in a number is a relatively simple process, but it depends on a clear understanding of four main rules. The examples below set out the guidance for each rule and provide various examples to help you understand how the calculation is being made in each case. Should you wish to check your calculations at any point, you can use our sig figs calculator.

Rule 1 – Non-zero digits are ALWAYS significant

This is a fundamental rule and the easiest to understand. Any non-zero digit in a number must be considered as significant.

Examples:

1.1 has two significant figures (1, 1). 13.55 has four significant figures (1, 3, 5, 5).

Rule 2 – any zero contained between two non-zero numbers is significant

If a zero forms part of a string of digits AND falls between two non-zero digits then it must be counted as a significant figure.

Examples:

1.05 has three significant figures (1, 0, 5); the zero is enclosed by non-zero digits and should be counted. 100.45001 has eight significant figures (1, 0, 0, 4, 5, 0, 0, 1); all the zeroes in this number are enclosed by non-zero digits and therefore should be counted.

Where there are leading or trailing zeroes in a number, there are some other factors which come into play, specifically around the placement of the zeroes relative to any decimal point and other digits.

Rule 3 – leading zeroes are never significant

Any leading zeroes are never significant, irrespective of a decimal point

Examples:

0.05 – one significant figure (5); the leading zeroes are ignored. 0.0501 – three significant figures (5, 0, 1); the leading zeroes are ignored, the third zero is enclosed by two non-zero digits and is therefore significant.

Rule 4 – final or trailing zeroes are significant only after a decimal point

Zeroes contained before or after a decimal point are considered as significant figures if they fall between two non-zero digits, as per rule 2, OR potentially when they are trailing, not leading zeroes. Trailing zeroes are only counted when a decimal point is included in the number, as shown below.

This is the hardest rule to grasp and requires various examples to explain.

Examples:

1.005 – four significant figures (1, 0, 0, 5); the zeroes are automatically counted as they fall between two non-zero digits. 0.005 – one significant figure (5); the leading zeroes do not fall between two non-zero digits and only the 5 is considered significant. 0.00500 – three significant figures (5, 0, 0); the leading zeroes do not count (as per Rule 3) but the two trailing zeroes are considered to be significant as they come after a decimal point. So in this example the three significant figures are the 5 and the final two zeroes. 500 – one significant figure (5); there is no decimal point and therefore the two zeroes do not add anything to the “precision” of the number. However, if a decimal point is present then these zeroes will become significant, as per example 5). 500.00 – five significant figures (5, 0, 0, 0, 0). The four trailing zeroes are all significant due to the decimal point which adds precision to the number.

These four basic rules will help determine the number of significant figures in any number. However if you wish to do mathematical calculations and still work out the number of significant figures then a new set of rules comes into play! These rules also differ depending on whether you are combining numbers in an addition or subtraction, or performing multiplication or division.

Addition rules and subtraction rules for significant figures

Add up the number of significant figures to the right of the decimal part of each number used in the calculation. Perform the calculation (addition or subtraction) as usual. The answer must not contain more significant figures to the right of the decimal point than the fewest of any of the figures worked out in part 1. So for example if you are adding together two numbers with three and four significant figures to the right of the decimal point, the answer cannot have more than three significant figures to the right of the point.

Example calculation showing addition: Add together 1.13 and 2.2

1.13 has two significant figures to the right of the decimal point, whereas 2.2 has one in the decimal part. The answer therefore also cannot have more than one!

1.13 + 2.2 = 3.33

As the answer cannot have more than 1 significant figure in the decimal part, you must round the result as appropriate, giving a final answer of 3.3.

Example 2 – subtract 1.55 from 3.2

1.55 has two significant figures in the decimal part, while 3.2 has one – the answer must also therefore only have one.

3.2 – 1.55 = 1.65

Round the number to give a final answer of 1.7

Note in this case that if we had been asked to subtract 1.55 from 3.20 (the trailing zero being significant) the answer can have two significant figures and would be correctly deemed to be 1.65!

Multiplication rules and division rules for significant figure calculations

Unlike the addition and subtraction example, you now must calculate the number of significant figures in each number in its entirely before performing the calculation, not just the decimal part. Once you have performed the calculation, the answer now must contain the same number of significant figures as the smallest total of them in the initial numbers.

Examples

a) multiply 3.1 by 3.5 Each number has two significant figures therefore the answer can have a maximum of two significant figures. 3.1 x 3.5 = 10.85 However 10.85 has four significant figures and therefore must be rounded to 11, which has two. So in this case the correct answer is 11.

b) multiply 3.10 by 3.50 Each number has three significant figures, so the answer can have a maximum of three. 3.10 x 3.50 = 10.85 Again, round this number appropriately to create an answer with three significant figures – in this case the answer is now 10.9!

c) multiply 3.100 by 3.500 Each number in the question has four significant figures and therefore the answer must too. 3.100 x 3.500 = 10.85 This answer (10.85) has four significant figures and therefore remains the correct one to use.

These examples cover many of the most common types of significant figure calculations and should help you answer questions on this topic. It’s important to learn the rules around zeroes and particularly the difference between calculations involving addition/subtraction and multiplication/division as this is where most errors occur.

MATH STUDIES Custom Search Number and Algebra Significant Figures Estimating is process normally used to see if your answer is of the correct order. However you will often be asked in exams to give your answer either exactly or to a certain degree of accuracy this can either be to a certain number of significant figures or a certain number of decimal places. Remember whatever the degree of accuracy used, the answer represents an approximation of the answer and should still be of the same order Leading zeros do not count. The first significant figure is the first non-zero value. Example: 0.001, 1 is the significant figure, hence 0.001 has one significant figure. Trailing zeros before the decimal point do not count. Example: 10, 100, 1000 all have only one significant figure. Zeros ‘sandwiched’ between non-zero values count. Example: 101 three significant figures, 1001 four significant figures etc. Trailing zeros after a decimal point count if preceded by a non-zero value. Example: 0.01 one significant figure, 0.010 two significant figures, 0.0100 three significant figures. The reason these zeros are considered is because it shows the accuracy to which the value has been taken. This is important in science experiments. When giving a value to a certain number of significant figures, say x, then if the (x+1)th value is less than five, then the x value remains the same, however if the (x+1)th value is five or more then the x value is increased by one. Example: Give the following numbers correct to 3 significant figures 3.5444 ≈ 3.54 3.5455 ≈ 3.55

zero point zero two Explanation:

0.020 has two significant figures.

The 2 is significant because all non-zero numbers are signficant.

The second 0 is significant because all zeros at the end of a decimal are significant.

The other zeros are not significant, because they are just place holders.

How to find significant numbers by using the Internet can become a daunting task, particularly if you do not have much experience. You may end up phoning the number and finding out nothing. However, you must not give up and just keep trying until you have the information you require.

Firstly, you need to check the numbers. If you cannot find it, move on and leave the numbers behind. Secondly, find out from friends, family members or colleagues who they know who might have gotten calls from that particular number. Do not ignore this Sig Fig formulae simply because you do not want to think about the possibility of someone else being involved.

Try finding the significant figures. Some websites may not list numbers in their formulae because of privacy issues. However, the majority will include formulae. Get their website addresses and put the numbers which you want to get sig fig numbers, and call them up one at a time. The more information you have the better.

If you find that you have several numbers to investigate, then you need to use one of the reverse lookup directories. They can provide you with the name of the blogs, their web address, and other details related to that blogs. They can even help you find out their service provider and get their web directory. This is important if you are trying to find sig fig calculations. These blogs will be able to tell you where the numbers are, and what is the results.

If you find a calculator that has been any significant numbers for that matter, do not reply. If you answer, you will provide yourself with another opportunity for the caller to harass you. It is best to just cut the call short. This option will prevent you from providing the numbers that you find to anyone else. How to find significant numbers online is to avoid the problem by not giving out the information to anyone.

You can also find out how to find significant numbers online by using internet search engines. Enter the number in the appropriate search field, and hit enter. If the number is listed, the results will list the name of the owner of the number, and their current billing address. This gives you a third party, accurate look into exactly who the person is that is calling you.

Are you being harassed by telephone calls? Have you tried looking up some phone numbers on a reverse phone lookup site but found no results? Now you can use the services of a reverse lookup service to find out who owns the phone numbers you have found. It is a simple step by step process and will allow you to know exactly who is behind these calls.

The system will then produce a report about the owner of the phone number you have searched. It should provide the names of the owners of the numbers, as well as their current billing address. This is a great way to catch those annoying pranksters.

So now you know how to find people with a phone number, how about how to find numbers with the Internet? There are many companies out there that specialize in offering cell phone reverse lookups. They can help you find all kinds of numbers. This includes cell phone numbers. They offer reverse look-ups for landline, cell phone, unlisted numbers, and more.

Of course you may be worried about your privacy, but you can rest assured that these companies will never sell this information to anyone. They will only purchase it from the companies that maintain their databases. In order to save yourself even more money, you may want to find a company that allows you unlimited searches for one time only fee. By using this option, you will only pay for the information once and then you can use it again to find the information you need.
