How to convert kilojoules to International Table Btu
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 Btu IT.
Btu IT = kJ × 1000 ÷ 1055.05585262
Worked examples
10 kJ ≈ 9.47817120313 Btu IT
Step 1: (10 × 1000) ≈ 10000 J.
Step 2: 10000 ÷ 1055.05585262 ≈ 9.47817120313 Btu IT.20 kJ ≈ 18.9563424063 Btu IT
Step 1: (20 × 1000) ≈ 20000 J.
Step 2: 20000 ÷ 1055.05585262 ≈ 18.9563424063 Btu IT.
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.
