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 microkelvin
The per microkelvin (1/μK) equals exactly 10⁶ /K. It is used in ultra-precision experiments probing anomalous thermal expansion extremely close to second-order phase transitions, such as the superfluid He-4 lambda point (2.1768 K) and magnetic phase boundaries in rare-earth compounds. 1 /μK = 10⁶ /K = 10¹² ppm/K.
