Convert Per microkelvin to ppb per kelvin
Convert Per microkelvin (1/μK) to ppb per kelvin (ppb/K) instantly and accurately.
Conversion Formula
ppb/K = 1/μK × 1000000000000000
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 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.
