Formula

ε = ΔL / L₀

ε: strain (dimensionless), ΔL: change in length, L₀: original length

How to Use

  1. Enter length change ΔL.
  2. Enter original length L₀.
  3. Get strain ε (dimensionless).

Case Studies

1 mm stretch on 1 m bar

ε = 0.001 / 1 = 0.001 = 0.1%.

FAQ

Does strain have units?

Dimensionless, often given as a percentage.

Relation to stress?

In linear elasticity σ = E·ε (Hooke's law).
