Convert Minute-degree Fahrenheit per BTU to Hour-degree Celsius per kilocalorie
Convert Minute-degree Fahrenheit per BTU (min·°F/BTU) to Hour-degree Celsius per kilocalorie (h·°C/kcal) instantly and accurately.
Conversion Formula
h·°C/kcal = min·°F/BTU × 0.03674371036
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 Hour-degree Celsius per kilocalorie
The h·°C/kcal equals 3600/4186.8 K/W ≈ 0.8598 K/W. Used in pre-SI European engineering literature (French, German, Italian) for heat transfer system calculations. A boiler with 1 h·°C/kcal resistance passes 1 kcal/h per °C temperature difference. Superseded by K/W and h·°C/W in modern standards. 1 h·°C/kcal ≈ 0.8598 K/W.
