BTU per degree Fahrenheit to kilojoules per kelvin
Type a value in BTU/°F to get it in kJ/K instantly.
18.99kJ/K
That's 2.7× as much heat capacity as a full kettle, while a person is 13× more. Warming it by 10 °C takes about 0.05275 kWh.
Convert the other way: kJ/K to BTU/°F
What it means
How much heat does it hold?
Examples are water-filled unless stated: water takes 4,184 J to warm a kilogram by one degree. A person is taken as 70 kg.
The math
How to convert BTU/°F to kJ/K
To convert BTU per degree Fahrenheit to kilojoules per kelvin, multiply by 1.8991.
Example: 10 BTU/°F × 1.8991 = 18.991 kJ/K.
In the other direction, 1 kJ/K = 0.526565 BTU/°F.
