Enter the fracture or final length (in) and the initial length (in) into the Calculator. The calculator will evaluate the Percent Elongation.

## Percent Elongation Formula

PE = (FL - IL) / IL * 100

Variables:

- PE is the Percent Elongation (%)
- FL is the fracture or final length (in)
- IL is the initial length (in)

To calculate the Percent Elongation, divide the difference between the final and initial length

## How to Calculate Percent Elongation?

The following steps outline how to calculate the Percent Elongation.

- First, determine the fracture or final length (in).
- Next, determine the initial length (in).
- Next, gather the formula from above = PE = (FL – IL) / IL * 100.
- Finally, calculate the Percent Elongation.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

fracture or final length (in) = 45

initial length (in) = 100
