Conversion Formula

ppb/K = 1/mK × 1000000000000

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.

About ppb per kelvin

The ppb/K (parts per billion per kelvin) equals 10⁻⁹ /K and is the resolution unit for ultra-low-CTE materials. Zerodur Class 0 (±0.02 ppb/K) and ULE titanium-silicate glass (±0.03 ppb/K) at 20 °C are characterised in ppb/K for gravitational-wave interferometers and space telescope optical benches. 1 ppb/K = 10⁻⁹ /K = 10⁻³ ppm/K.
