Convert Minute-degree Fahrenheit per BTU to Kelvin per watt
Convert Minute-degree Fahrenheit per BTU (min·°F/BTU) to Kelvin per watt (K/W) instantly and accurately.
Conversion Formula
K/W = min·°F/BTU × 0.03159390401
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 Kelvin per watt
The kelvin per watt (K/W) is the SI coherent unit for thermal resistance, defined as the temperature rise (K) per unit of steady-state power dissipation (W). Used universally in electronic component datasheets (junction-to-ambient, junction-to-case), heat sink ratings, and thermal circuit analysis. A CPU heatsink at 0.3 K/W raises temperature 30 K per 100 W. 1 K/W = 1 °C/W.
