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 Per millikelvin
The per millikelvin (1/mK) equals exactly 10³ /K and is encountered in cryogenic physics where working temperatures lie in the millikelvin range. Near quantum phase transitions and magnetic ordering temperatures, anomalous CTE values can reach orders far above room-temperature CTE. 1 /mK = 10³ /K = 10⁹ ppm/K.
