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).
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).
