BTU per pound-°F to joules per kilogram-kelvin
Type a value in BTU/(lb·°F) to get it in J/(kg·K) instantly.
4,186,800J/(kg·K)
That's 1,001× as much heat as water — nothing on our list beats it. Warming one kilogram by 10 °C takes about 41,870,000 J.
Convert the other way: J/(kg·K) to BTU/(lb·°F)
What it means
How much heat does it hold?
Values are at room temperature and constant pressure. Gases differ between constant pressure and constant volume.
The math
How to convert BTU/(lb·°F) to J/(kg·K)
To convert BTU per pound-°F to joules per kilogram-kelvin, multiply by 4,186.8.
Example: 1,000 BTU/(lb·°F) × 4,186.8 = 4,186,800 J/(kg·K).
In the other direction, 1 J/(kg·K) = 0.000238846 BTU/(lb·°F).
