Heat Capacity Converter
Convert heat capacity among J/K, kJ/K, and BTU/°F using J/K as the reference.
How to use
- Enter whole-object heat capacity and select its source and target among J/K, kJ/K, and BTU/°F.
Capabilities and scope
Heat capacity is the energy needed to change the temperature of an entire object by one degree; it is distinct from specific heat per unit mass.
How it works
J/K is the reference with kJ/K=1000 J/K and 1 BTU/°F≈1899.1005 J/K.
Example
1 kJ/K is 1000 J/K, or about 0.526565 BTU/°F.
Useful for
- Convert equipment heat capacity to SI
- Compare BTU/°F literature with J/K
- Align thermal-model input units
Before you use it
- Specific heat capacity such as J/(kg·K) is a different mass-normalized quantity and is not included.

Frequently asked questions
Are heat capacity and specific heat the same?
No. Heat capacity is for the whole object (J/K); specific heat is usually per unit mass (J/(kg·K)).
