# What is the Easiest Way to Identify Significant Figures?

Aug 26, 2021

Counting or identifying significant digits can often get confusing sometimes. If you are not aware of the basic rules and what goes on behind the scenes when identifying significant figures, it is going to take you a lot of time to get a hang of it.

Scientists and mathematicians have created a set of principles to identify significant figures in a given value.

These principles or rules allow you to narrow down a value down to its most important, useful, or significant numbers that they use to produce the same results as the complete number.

Let’s get started and talk about Significant Figures and you can calculate them easily.

## What are Significant Figures and Why Are They Needed

Significant Figures or Digits are numbers in a value that are “meaningful” and that can accurately represent the message given by the original value.

Significant Figures are of incredible importance for doing various mathematical calculations. The use of Significant Figures enables you to bring precision and accuracy in your calculations.

The significant figures are important digits in a value, and they show the accuracy and precision of that value when they are used in mathematical or engineering calculations.

Throughout the rest of this article, we are going to go over some easy methods that you can use to identify significant numbers.

## How to Identify Significant Figures Easily

You can easily identify the significant figures if you just know the rules for identifying them.

After careful analysis, scientists have come up with a set of rules that govern the identification of significant figures. This set of rules is simple to understand and makes it easy for everyone to identify significant digits.

### Rules for Significant Figures

Here are the rules for significant figures that you can use to identify them in a value.

1. If a value consists of non-zero digits, then all the numbers in that value are significant. For example, the term 43.266 has 4 significant digits.
2. If one or more zeros come between 2 non-zero digits, then those zeros would be significant. For example, the term 45.0078 has 6 significant figures.
3.  Zeros that come at the right-hand side of a decimal point or the left of the non-zero digits are not significant. For example, the term 0.0075 has 2 significant digits.
4. If zeros are placed on the right-hand side of the decimal point and they don’t have a non-zero digit after them, then those zeros are significant. For example, the term 72.00 has 4 significant digits.
5. Zeros that come on the right-hand side of the non-zero digits in a value with a decimal point are significant. For example, the value 0.0078200 has 5 significant figures.
