thermochemical kilocalorie per kelvin to joule per kelvin
Convert thermochemical kilocalorie per kelvin (kcal/K) to joule per kelvin (J/K). Use an editable heat capacity converter, conversion formula, and reference table.
1 kcal/K = 4,184 J/K
Conversion formula
One thermochemical kilocalorie per kelvin equals 4,184 joule per kelvin. Multiply your value in thermochemical kilocalorie per kelvin by this factor to get joule per kelvin. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 thermochemical kilocalorie per kelvin:5 × 4,184 = 20,920 J/K

About these measurements
Heat capacity is the energy needed per unit temperature change.
The base reference used here is the joule per kelvin. One thermochemical kilocalorie per kelvin is 4,184 base units; one joule per kelvin is 1 base units.
Important distinctions
Compound units must match the quantity and dimension. Temperature intervals use size factors rather than temperature offsets. Calorie and BTU entries use the explicit definitions shown.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
Common questions
