What is being measured?
Heat capacity relates heat transfer to a temperature change under specified conditions. It is distinct from specific heat capacity per mass.
Temperature denominator is an interval; do not apply absolute-temperature offset. Heat capacity differs from specific heat capacity.
Choose a unit definition
Symbols, prefixes and conventions matter. Each row links to a definition, a worked example and a comparison table. Units of different quantities are kept separate even when symbols or dimensions look similar.

Thermochemical calories per kelvin (cal th/K)
Definition, reference values and linked conversions.
Thermochemical kilocalories per kelvin (kcal th/K)

International-table BTU per Fahrenheit degree (BTU IT/°F)

Choose the conversion direction
Start with the unit attached to the original measurement. Select the unit needed by the receiving report, specification or formula. Conversion tools preserve the measured quantity; calculating another property can require additional measured inputs and assumptions.
Precision and common mistakes
- Keep the source and target quantity consistent. A matching symbol is not enough to establish a compatible definition.
- Record the original measurement precision. Showing twelve significant digits in a table does not make a rounded input more precise.
- Check symbol capitalization, prefixes and any regional convention in the source. Use the displayed unit definition rather than a similarly named unit.
- Factors involving repeating fractions or π use finite numerical precision. Round the final answer to the precision justified by your input.
