Convert Millimetres per metre per kelvin to Per millikelvin
Convert Millimetres per metre per kelvin (mm/(m·K)) to Per millikelvin (1/mK) instantly and accurately.
Conversion Formula
1/mK = mm/(m·K) × 1.000000000e-6
About Millimetres per metre per kelvin
The mm/(m·K) equals exactly 10⁻³ /K = 1000 ppm/K and is used in structural and civil engineering for bridge girder and pipeline thermal-expansion calculations. Steel at 0.012 mm/(m·K) expands 12 mm per 100 m track per 10 K rise. Polymers: 0.07-0.20 mm/(m·K). 1 mm/(m·K) = 10⁻³ /K = 1000 ppm/K.
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.
