How to convert kilojoules to thermochemical calories
Calories use the thermochemical definition. Btu use the International Table definition. Food Calories are kilocalories, not single calories.
Use x for the value in kJ, b for the intermediate value in J, and y for the result in cal.
cal = kJ × 1000 ÷ 4.184
Worked examples
10 kJ ≈ 2390.05736138 cal
Step 1: (10 × 1000) ≈ 10000 J.
Step 2: 10000 ÷ 4.184 ≈ 2390.05736138 cal.20 kJ ≈ 4780.11472275 cal
Step 1: (20 × 1000) ≈ 20000 J.
Step 2: 20000 ÷ 4.184 ≈ 4780.11472275 cal.
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
About Kilojoules
Kilojoules (kJ) measures energy under the conventions above. The base value in J is (x × 1000), where x is the numerical value in kJ. Factors shown here are rounded for display; calculations use the stored factor.
About Thermochemical calories
Thermochemical calories (cal) measures energy under the conventions above. The base value in J is (x × 4.184), where x is the numerical value in cal. Factors shown here are rounded for display; calculations use the stored factor.
