Thermal Expansion Calculator
Calculate linear thermal expansion using ΔL = αLΔT. Enter original length, expansion coefficient, and temperature change.
How to Use the Thermal Expansion Calculator
- Enter the original length of the material in meters.
- Enter the linear expansion coefficient (e.g. 0.000012 for steel).
- Enter the temperature change in °C.

計算式
ΔL = α × L₀ × ΔT, where ΔL is length change (m), α is the coefficient of linear expansion (1/°C), L₀ is original length (m), ΔT is temperature change.
よくある質問
What is the coefficient of linear expansion?
It measures how much a material expands per unit length per degree temperature change. Steel has α ≈ 12×10⁻⁶ /°C.
Does this work for all materials?
Yes, as long as you provide the correct coefficient. Common values: steel 12, aluminum 23, copper 17 (×10⁻⁶ /°C).
Is this calculator free?
Yes, all OhMyCalc calculators are completely free.
