How to convert International Table Btu to kilowatt-hours
Calories use the thermochemical definition. Btu use the International Table definition. Food Calories are kilocalories, not single calories.
Use x for the value in Btu IT, b for the intermediate value in J, and y for the result in kWh.
kWh = Btu IT × 1055.05585262 ÷ 3600000
Worked examples
10 Btu IT ≈ 0.00293071070172 kWh
Step 1: (10 × 1055.05585262) ≈ 10550.5585262 J.
Step 2: 10550.5585262 ÷ 3600000 ≈ 0.00293071070172 kWh.20 Btu IT ≈ 0.00586142140344 kWh
Step 1: (20 × 1055.05585262) ≈ 21101.1170524 J.
Step 2: 21101.1170524 ÷ 3600000 ≈ 0.00586142140344 kWh.
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.
