Per millikelvin (1/mK)

Conversion Formula

1/mK = 1/°C × 0.001

About Per degree Celsius

The per degree Celsius (1/°C = °C⁻¹) equals exactly 1/K since temperature intervals 1 °C = 1 K (exact). Common in European and ISO standards, chemistry textbooks, and physics literature as an alternative notation for the SI unit 1/K. A material with α = 12 × 10⁻⁶ /K is identically expressed as 12 × 10⁻⁶ /°C. 1 /°C = 1 /K = 10⁶ 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.
