Convert
Accuracy and rounding
Convert thermochemical small-calorie energy values used in chemistry and physics, not food Calories. One thermochemical calorie is exactly 4.184 joules.
Energy units share a fixed joule reference. Food Calories are kilocalories; this calculator uses the thermochemical calorie at exactly 4.184 joules and the International Table BTU.
For billing, nutrition, or engineering, match the precision of the original joules data and keep the energy/power distinction explicit.
How to convert thermochemical calories to joules
- Enter the value in thermochemical calories.
- Select thermochemical calories as the source unit.
- Select joules as the target unit.
- Read or copy the result.

Common questions
How do I convert thermochemical calories to joules?
Enter the thermochemical calories value in the converter, or multiply by the factor shown in the formula. 1 cal = 4.184 J.
What should I watch out for?
Do not confuse energy with power: kWh is accumulated energy, while kW is a rate of energy transfer.
Where does this energy conversion come from?
Energy factors from NIST SI conversion tables, using the joule as the shared reference unit. ConverterBase uses stable definitions and fixed conversion factors, not live or rounded market data.
