Convert Thermochemical calorie per gram per degree Celsius to International table BTU per pound per degree Fahrenheit
Convert Thermochemical calorie per gram per degree Celsius (cal(th)/(g·°C)) to International table BTU per pound per degree Fahrenheit (BTU(IT)/(lb·°F)) instantly and accurately.
Conversion Formula
BTU(IT)/(lb·°F) = cal(th)/(g·°C) × 0.9993312315
About Thermochemical calorie per gram per degree Celsius
The thermochemical calorie per gram per degree Celsius (cal(th)/(g·°C)) equals exactly 4184 J/(kg·K) (1 cal(th) = 4.184 J). The CGS unit of specific heat dominant in older US chemistry and biochemistry. Liquid water has a specific heat of almost exactly 1 cal(th)/(g·°C). Slightly smaller than the IT counterpart. 1 cal(th)/(g·°C) = 4184 J/(kg·K) = 1 kcal(th)/(kg·°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).
