Convert International table calorie per gram per degree Celsius to International table BTU per pound per degree Fahrenheit
Convert International table calorie per gram per degree Celsius (cal(IT)/(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(IT)/(g·°C) × 1
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).
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).
