Convert Celsius Heat Unit per pound per degree Celsius to International table calorie per gram per degree Celsius
Convert Celsius Heat Unit per pound per degree Celsius (CHU/(lb·°C)) to International table calorie per gram per degree Celsius (cal(IT)/(g·°C)) instantly and accurately.
Conversion Formula
cal(IT)/(g·°C) = CHU/(lb·°C) × 1
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).
About International table calorie per gram per degree Celsius
The international table calorie per gram per degree Celsius (cal(IT)/(g·°C)) equals exactly 4186.8 J/(kg·K) (1 cal(IT) = 4.1868 J). Standard in steam tables, international thermodynamic references, and pre-SI calorimetry. Slightly larger than the thermochemical variant. Water: 1 cal(IT)/(g·°C) at ≈15 °C. 1 cal(IT)/(g·°C) = 4186.8 J/(kg·K) = 1 kcal(IT)/(kg·°C).
