Linear Thermal Expansion

Initial Length (L0)

Expansion Coefficient (α) [10⁻⁶ m/(m K)]

Value is in micro-units per degree (10⁻⁶).

Temperature Change (ΔT)

Final Length: --

About Expansion

Most materials expand when heated. This calculator finds the linear expansion (ΔL) using the formula:

ΔL = L0 * α * ΔT
