About Per kelvin
The per kelvin (1/K = K⁻¹) is the SI unit for linear thermal expansion coefficient (α = (1/L) dL/dT). Used in NIST databases, FEA material cards, and thermodynamics textbooks. Liquid mercury: ≈6.1 × 10⁻⁵ /K; aluminium: ≈2.3 × 10⁻⁵ /K; fused silica: ≈5.5 × 10⁻⁷ /K. 1 /K = 10⁶ ppm/K = 1/°C.
About Millimetres per metre per degree Fahrenheit
The mm/(m·°F) equals 9/5 × 10⁻³ /K ≈1.8 × 10⁻³ /K, combining metric displacement with Fahrenheit temperature. It appears in US-origin pipeline and structural reports where dimensions are given in metres but temperatures in °F. Steel: ≈0.00667 mm/(m·°F); aluminium: ≈0.01283 mm/(m·°F). 1 mm/(m·°F) = 9/5 × 10⁻³ /K.
