Convert Minute-degree Fahrenheit per BTU to Kilokelvin per watt
Convert Minute-degree Fahrenheit per BTU (min·°F/BTU) to Kilokelvin per watt (kK/W) instantly and accurately.
Conversion Formula
kK/W = min·°F/BTU × 3.159390401e-5
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 Kilokelvin per watt
The kilokelvin per watt (kK/W) equals exactly 1000 K/W. Used for high thermal resistances in aerogel films, vacuum insulation panels with small contact area, and micron-scale thin-film insulation layers in microelectronics packaging. Numerically identical to °C/mW; both notations denote the same thermal resistance in different engineering contexts. 1 kK/W = 1000 K/W = 1 °C/mW.
