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 Microns per metre per degree Celsius

The micrometre per metre per degree Celsius (μm/(m·°C)) equals exactly 10⁻⁶ /K, since temperature intervals 1 °C = 1 K (exact). It is the standard CTE notation in European engineering datasheets, ISO material standards, and many textbooks. Numerically identical to ppm/K. Aluminium: 23.1 μm/(m·°C); steel: ≈12 μm/(m·°C). 1 μm/(m·°C) = 1 ppm/K = 10⁻⁶ /K.
