joule to thermochemical kilocalorie
Convert joule (J) to thermochemical kilocalorie (kcal). Use an editable energy converter, conversion formula, and reference table.
1 J = 0.0002390057361 kcal
Conversion formula
One joule equals 0.0002390057361 thermochemical kilocalorie. Multiply your value in joule by this factor to get thermochemical kilocalorie. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 joule:5 × 0.0002390057361 = 0.001195028681 kcal

About these measurements
Energy can be transferred through work, heating, or electrical processes.
The base reference used here is the joule. One joule is 1 base units; one thermochemical kilocalorie is 4,184 base units.
Important distinctions
Calorie and BTU definitions vary. These pages label thermochemical calories and International Table BTUs explicitly.
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
How do I convert J to kcal?
Multiply the quantity in J by 0.0002390057361. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the thermochemical kilocalorie to joule converter.
