What is the formula for Linear Thermal Expansion Calculator (ΔL=αL₀ΔT)?

Core formula: ΔL = α·L₀·ΔT. The tool returns results instantly using this formula and the selected parameters.

What engineering notes should I keep in mind when using Linear Thermal Expansion Calculator (ΔL=αL₀ΔT)?

Linear expansion ΔL = α·L₀·ΔT: α is the coefficient of linear expansion in 1/°C; most metals have α on the order of 10⁻⁵. Common α (×10⁻⁶/°C): copper 17, aluminum 23, steel ≈ 12, glass ≈ 9, concrete ≈ 10. Long pipes / rails / bridges need expansion joints; otherwise tens of degrees of temperature change produce significant deformation and thermal stress.
