Convert International table BTU per pound per degree Fahrenheit to Celsius Heat Unit per pound per degree Celsius
Convert International table BTU per pound per degree Fahrenheit (BTU(IT)/(lb·°F)) to Celsius Heat Unit per pound per degree Celsius (CHU/(lb·°C)) instantly and accurately.
Conversion Formula
CHU/(lb·°C) = BTU(IT)/(lb·°F) × 1
About International table BTU per pound per degree Fahrenheit
The international table BTU per pound per degree Fahrenheit (BTU(IT)/(lb·°F)) equals (1055.05585262 × 9)/(0.45359237 × 5) J/(kg·K) = 4186.8 J/(kg·K). The standard US unit for specific heat capacity in ASHRAE, ASTM, and mechanical engineering references. Water: 1.000 BTU(IT)/(lb·°F); steel: ≈0.108; air: ≈0.240. 1 BTU(IT)/(lb·°F) = 4186.8 J/(kg·K).
About Celsius Heat Unit per pound per degree Celsius
The Celsius heat unit per pound per degree Celsius (CHU/(lb·°C)) equals exactly (1055.05585262 × 9)/(0.45359237 × 5) J/(kg·K) = 4186.8 J/(kg·K). The CHU is 9/5 BTU(IT); combined with a 1 °C instead of 1 °F interval the factor is the same as BTU(IT)/(lb·°F). Used in older UK and Canadian engineering practice. Water: 1 CHU/(lb·°C). 1 CHU/(lb·°C) = 4186.8 J/(kg·K).
