Convert Minute-degree Fahrenheit per BTU to Millikelvin per watt
Convert Minute-degree Fahrenheit per BTU (min·°F/BTU) to Millikelvin per watt (mK/W) instantly and accurately.
Conversion Formula
mK/W = min·°F/BTU × 31.59390401
About Minute-degree Fahrenheit per BTU
The minute-degree Fahrenheit per BTU (min·°F/BTU) equals (5/9 × 60)/1055.05585262 K/W ≈ 0.03159 K/W. Used in US refrigeration and air-conditioning engineering where capacity is expressed in BTU/min - 1 ton of refrigeration equals 200 BTU/min. Thermal resistance of evaporator and condenser circuits is conveniently quoted in this unit. 1 min·°F/BTU ≈ 0.03159 K/W = 60 s·°F/BTU.
About Millikelvin per watt
The millikelvin per watt (mK/W) equals exactly 10⁻³ K/W. It is used for ultra-low thermal resistances in high-conductivity materials such as diamond heat spreaders (≈ 0.3 mK/W per mm thickness for 1 cm² area), liquid metal TIMs, and cryogenic heat links. Measuring at this scale requires precision power dissipation and calorimetric temperature sensing. 1 mK/W = 10⁻³ K/W.
