Thermal Expansion Calculator

Calculate linear (ΔL = α·L₀·ΔT) and volumetric (ΔV = β·V₀·ΔT, β ≈ 3α) thermal expansion for common materials.

Linear Expansion — ΔL = α × L₀ × ΔT

Volumetric Expansion — ΔV = β × V₀ × ΔT (β ≈ 3α)

Units for length/volume can be any (m, cm, mm, etc.) — output is in same units.
