## How to calculate Percentage Error?

The percentage error is a calculator to calculate the error between the

**approximate value**and

**exact value**.

**Formula to calculate percentage error is,**

| | Approx Value | - | Exact Value | | | |||

= | × | 100 | |||||

Exact Value |

The "

**|**" symbols is known as an

**absolute**value, therefore negative values become positive.

here,

*is the difference between Approx Value and Exact Value.*

**Absolute error**Dividing the absolute error by exact value we get

**.**

*Relative Error*Multiplying relative error by 100 we get

*percentage error.*

**Example,**

Mike does an experiment to find how long it takes a football to drop 5 meters.

Mike measures, football takes 2.6 seconds to drop 5 meters. which is an approx value.

Now, mike did some calculations and got the answer which is 3 sec which is an exact value.

**Formula to calculate percentage error is,**

| | Approx Value | - | Exact Value | | | |||
