How to convert Btu IT per pound to kilowatt-hours per kilogram
This family describes energy content or energy-normalized fuel use, not kilometers per kilogram. Heating values depend on the fuel and on higher versus lower heating-value conventions. Grams per kWh is the reciprocal of energy per mass.
Use x for the value in Btu IT/lb, b for the intermediate value in J/kg, and y for the result in kWh/kg.
kWh/kg = Btu IT/lb × 2326 ÷ 3600000
Worked examples
10 Btu IT/lb ≈ 0.00646111111111 kWh/kg
Step 1: (10 × 2326) ≈ 23260 J/kg.
Step 2: 23260 ÷ 3600000 ≈ 0.00646111111111 kWh/kg.20 Btu IT/lb ≈ 0.0129222222222 kWh/kg
Step 1: (20 × 2326) ≈ 46520 J/kg.
Step 2: 46520 ÷ 3600000 ≈ 0.0129222222222 kWh/kg.
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 Btu IT per pound
