Convert Thermochemical BTU per pound per degree Fahrenheit to Thermochemical kilocalorie per kilogram per degree Celsius
Convert Thermochemical BTU per pound per degree Fahrenheit (BTU(th)/(lb·°F)) to Thermochemical kilocalorie per kilogram per degree Celsius (kcal(th)/(kg·°C)) instantly and accurately.
Conversion Formula
kcal(th)/(kg·°C) = BTU(th)/(lb·°F) × 1
About Thermochemical BTU per pound per degree Fahrenheit
The thermochemical BTU per pound per degree Fahrenheit (BTU(th)/(lb·°F)) equals exactly 4184 J/(kg·K) (derived: 1 BTU(th) = 1054.350264 J; /lb/°F). Numerically identical to cal(th)/(g·°C) because both are defined via the thermochemical calorie. Used in older American thermodynamic tables. Water ≈1 BTU(th)/(lb·°F). 1 BTU(th)/(lb·°F) = 4184 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).
