Convert Minute-degree Fahrenheit per BTU to Degree Celsius per watt
Convert Minute-degree Fahrenheit per BTU (min·°F/BTU) to Degree Celsius per watt (°C/W) instantly and accurately.
Conversion Formula
°C/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 Degree Celsius per watt
The degree Celsius per watt (°C/W) equals exactly 1 K/W since temperature intervals 1 °C = 1 K. It is the dominant notation in semiconductor, LED, and power electronics datasheets worldwide. Thermal resistance values such as RθJA (junction-to-ambient) and RθJC (junction-to-case) are almost universally quoted in °C/W. A package at 50 °C/W dissipating 2 W yields ΔT = 100 °C. 1 °C/W = 1 K/W.
