Strain Calculator

Calculate the mechanical strain (ε) of a material, which is the ratio of its deformation (change in length) to its original length.

Strain Calculator

Note: Ensure that both measurements use the same unit (e.g., both in meters or both in millimeters).

How to Use

  1. 1

    Enter Change in Length

    Input the amount the material stretched (positive) or compressed (negative).

  2. 2

    Enter Original Length

    Input the starting length of the material. Ensure you use the exact same units as step 1.

  3. 3

    Calculate

    Click calculate to view the strain as a dimensionless decimal and as a percentage.
