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.

1. First, determine the fracture or final length (in).
2. Next, determine the initial length (in).
3. Next, gather the formula from above = PE = (FL – IL) / IL * 100.
4. Finally, calculate the Percent Elongation.
5. 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
