BTU per pound degree Fahrenheit quick reference
| BTU per pound degree Fahrenheit | Kilojoule per kilogram kelvin | Joule per kilogram kelvin | Calorie (IT) per gram degree Celsius |
|---|---|---|---|
| 1 BTU/(lb·°F) | = 4.1868 kJ/(kg·K) | = 4186.8 J/(kg·K) | = 1 cal/(g·°C) |
| 10 BTU/(lb·°F) | = 41.868 kJ/(kg·K) | = 41868 J/(kg·K) | = 10 cal/(g·°C) |
| 100 BTU/(lb·°F) | = 418.68 kJ/(kg·K) | = 418680 J/(kg·K) | = 100 cal/(g·°C) |
| 1000 BTU/(lb·°F) | = 4186.8 kJ/(kg·K) | = 4186800 J/(kg·K) | = 1000 cal/(g·°C) |
Where the BTU per pound degree Fahrenheit fits
The next smaller specific heat capacity unit is the kilojoule per kilogram kelvin (kJ/(kg·K)). 1 BTU/(lb·°F) = 4.1868 kJ/(kg·K), and 1 kJ/(kg·K) ≈ 0.2388458966 BTU/(lb·°F).
