Convert Celsius Heat Unit per pound per degree Celsius to Thermochemical kilocalorie per kilogram per degree Celsius
Convert Celsius Heat Unit per pound per degree Celsius (CHU/(lb·°C)) to Thermochemical kilocalorie per kilogram per degree Celsius (kcal(th)/(kg·°C)) instantly and accurately.
Conversion Formula
kcal(th)/(kg·°C) = CHU/(lb·°C) × 1.000669216
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 Thermochemical kilocalorie per kilogram per degree Celsius
The thermochemical kilocalorie per kilogram per degree Celsius (kcal(th)/(kg·°C)) equals exactly 4184 J/(kg·K) (1 kcal(th) = 4184 J = 1000 cal(th)). Used in older continental European and Soviet-era engineering tables as the practical metric unit. Water ≈1 kcal(th)/(kg·°C); iron ≈0.107 kcal(th)/(kg·°C). 1 kcal(th)/(kg·°C) = 4184 J/(kg·K) = 1 cal(th)/(g·°C).
