Convert Millimetres per metre per degree Fahrenheit to Per microkelvin
Convert Millimetres per metre per degree Fahrenheit (mm/(m·°F)) to Per microkelvin (1/μK) instantly and accurately.
Conversion Formula
1/μK = mm/(m·°F) × 1.800000000e-9
About Millimetres per metre per degree Fahrenheit
The mm/(m·°F) equals 9/5 × 10⁻³ /K ≈1.8 × 10⁻³ /K, combining metric displacement with Fahrenheit temperature. It appears in US-origin pipeline and structural reports where dimensions are given in metres but temperatures in °F. Steel: ≈0.00667 mm/(m·°F); aluminium: ≈0.01283 mm/(m·°F). 1 mm/(m·°F) = 9/5 × 10⁻³ /K.
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.
