## What is Percent Error?

Percent error, also known as percentage error or relative error, is a measure of the accuracy of a measurement or an approximation compared to the true or accepted value. It is used in science, engineering, and experimental research to assess how close a measured or calculated value is to the expected or true value.

## All Formulae Related to Percent Error

The formula for calculating percent error is as follows:

**Percent Error = [(|Measured Value – True Value|) / |True Value|] x 100%**

Where:

**Percent Error:**The percentage by which the measured value differs from the true value.**Measured Value:**The value obtained from a measurement or experiment.**True Value:**The actual or accepted value that is considered accurate or correct.

Here is an example of how to use this formula:

Suppose you are conducting an experiment to measure the speed of light and obtain a measured value of 299,792,458 meters per second (m/s). The accepted or true value for the speed of light is 299,792,458 m/s. You can calculate the percent error as follows:

**Percent Error = [(|299,792,458 m/s – 299,792,458 m/s|) / |299,792,458 m/s|] x 100% = 0%**
