How to Convert Specific Heat Capacity Units
Specific heat capacity is the energy needed to raise one unit of mass by one degree. The SI unit is joule per kilogram kelvin (J/(kg·K)); water is about 4186 J/(kg·K), which is 1 kcal/(kg·°C) or 1 BTU/(lb·°F).
Every unit on this page is stored as a fixed factor relative to one reference unit, the joule per kilogram kelvin (J/(kg·K)). Converting is a two step multiply and divide:
- Multiply your value by the factor of the source unit to get the value in J/(kg·K).
- Divide that result by the factor of the target unit.
