Convert Per microkelvin (1/μK) to ppb per degree Fahrenheit (ppb/°F) instantly and accurately.
Conversion Formula
ppb/°F = 1/μK × 555555555600000
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 degree Fahrenheit
The ppb/°F equals 9/5 × 10⁻⁹ /K ≈1.8 × 10⁻⁹ /K, the Fahrenheit counterpart of ppb/K. Used when ultra-low-expansion glass ceramics are characterised in US laboratories using Fahrenheit protocols. Zerodur at ±0.02 ppb/K ≈ ±0.011 ppb/°F. 1 ppb/°F = 9/5 × 10⁻⁹ /K ≈1.8 ppb/K.
