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.

About ppm per kelvin

The ppm/K (= μm/(m·K) exactly) equals 10⁻⁶ /K and is the universal CTE unit in international materials standards (ISO, EN, DIN). Aluminium: 23.1 ppm/K; steel: ≈12 ppm/K; ordinary glass: ≈9 ppm/K; fused silica: 0.55 ppm/K; Invar: ≈1.2 ppm/K. 1 ppm/K = 10⁻⁶ /K.
