Convert BTU per Pound °F to kcal/(kg·°C)
1 BTU per pound degree Fahrenheit (BTU/(lb·°F)) = 1 kilocalorie per kilogram degree Celsius (kcal/(kg·°C)). 1 kcal/(kg·°C) = 1 BTU/(lb·°F). Example: 15 BTU/(lb·°F) = 15 × 1 = 15 kcal/(kg·°C).

How to Convert BTU per Pound °F to Kilocalorie per Kilogram Degree Celsius
- 1 BTU/(lb·°F) = 1 kcal/(kg·°C)
- 1 kcal/(kg·°C) = 1 BTU/(lb·°F)
- Example: convert 15 BTU/(lb·°F) to kcal/(kg·°C): 15 BTU/(lb·°F) = 15 × 1 kcal/(kg·°C) = 15 kcal/(kg·°C)
Reference conditions. kcal/(kg·°C): International Table calorie (4.1868 J).
Formula
kcal/(kg·°C) = BTU/(lb·°F) × 1
Derivation from SI units:
- 1 BTU_IT/(lb·°F) = 4186.8 J/(kg·K) exactly (the BTU and the calorie scale the same way).
- 1 kcal_IT/(kg·°C) = 4186.8 J/(kg·K), the same number as cal/(g·°C).
- 1 BTU/(lb·°F) = 4186.8 J/(kg·K) ÷ 4186.8 J/(kg·K) per kcal/(kg·°C) = 1 kcal/(kg·°C)
Both units are defined exactly, so the factor is exact. BTU per Pound °F definition: BTU per pound degree Fahrenheit; Kilocalorie per Kilogram Degree Celsius definition: kilocalorie per kilogram degree Celsius.
Worked examples
- A reading of 0.12 BTU/(lb·°F) converts to 0.12 kcal/(kg·°C).
0.12 BTU/(lb·°F) × 1 = 0.12 kcal/(kg·°C) - A value of 0.45 BTU/(lb·°F) is 0.45 kcal/(kg·°C).
0.45 BTU/(lb·°F) × 1 = 0.45 kcal/(kg·°C)
