Type a value in kWh/K to get it in MJ/K instantly.
36MJ/K
That's 43× as much heat capacity as a hot-water cylinder, while an Olympic swimming pool is 291× more. Warming it by 10 °C takes about 100 kWh.
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 kWh/K to MJ/K
To convert kilowatt-hours per kelvin to megajoules per kelvin, multiply by 3.6.
Example: 10 kWh/K × 3.6 = 36 MJ/K.
In the other direction, 1 MJ/K = 0.277778 kWh/K.
