Strain Calculator

Find strain from length change.

Change in length

Original length

Calculated Output

Strain 0.001

Strain (%) 0.1

Formula: strain = ΔL ÷ L

Step-by-Step Breakdown

1. Values used:

2. Change in length = 0.002

3. Original length = 2

5. Strain = Change in length / Original length = 0.002 / 2 = 0.001

6. Strain = 0.1%

Did this calculator solve your problem today?

The math behind it

strain = change in length ÷ original length (dimensionless).

2 mm over 2 m → 0.001 (0.1%).

Units?

None — strain is a ratio.
