Thermal Expansion Calculator

Calculate linear thermal expansion from temperature change

Initial Length (m):

Coefficient of Linear Expansion (1/°C):

Temperature Change (°C):

Common coefficients (×10⁻⁶ /°C):

Steel: 12, Aluminum: 23, Copper: 17, Concrete: 12, Glass: 9

ΔL = αL₀ΔT (linear expansion)

L = L₀ + ΔL (final length)

Where: α = coefficient of linear expansion, L₀ = initial length, ΔT = temperature change
