How do I convert International-table BTU per Fahrenheit degree to Joules per kelvin?
Enter the known measurement and select its source and target units. The converter expresses the same heat capacity quantity in the target unit, using the stated definitions.
Common uses
- Compare measurements stated in different units.
- Translate a known value before using it in a formula or specification.
How it works
Convert through the shared base quantity using the two defined factors. Temperature denominator is an interval; do not apply absolute-temperature offset. Heat capacity differs from specific heat capacity. Conversion changes the unit of a known measurement; it does not calculate another physical quantity or imply a material model. Factors with π or repeating rational values use finite precision; results display up to 12 significant digits.
Worked example
10 BTU IT/°F equals approximately 18991.0053472 J/K. Reverse the units to convert in the other direction.
