megajoule to thermochemical kilocalorie
Convert megajoule (MJ) to thermochemical kilocalorie (kcal). Use an editable energy converter, conversion formula, and reference table.
1 MJ = 239.0057361 kcal
Conversion formula
One megajoule equals 239.0057361 thermochemical kilocalorie. Multiply your value in megajoule by this factor to get thermochemical kilocalorie. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 megajoule:5 × 239.0057361 = 1,195.028681 kcal

About these measurements
Energy can be transferred through work, heating, or electrical processes.
The base reference used here is the joule. One megajoule is 1,000,000 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.
