How to Convert BTU per Pound to Kilowatt-hour per Kilogram
- 1 BTU/lb = 0.0006461111111 kWh/kg
- 1 kWh/kg = 1547.72141 BTU/lb
- Example: convert 15 BTU/lb to kWh/kg: 15 BTU/lb = 15 × 0.0006461111111 kWh/kg = 0.009691666667 kWh/kg
Formula
kWh/kg = BTU/lb × 0.0006461111111111
or kWh/kg = BTU/lb ÷ 1547.721410146
Derivation from SI units:
- 1 BTU_IT/lb = 1055.05585262 J ÷ 0.45359237 kg = 2326 J/kg exactly.
- 1 kWh/kg = 3.6 × 10⁶ J/kg.
- 1 BTU/lb = 2326 J/kg ÷ 3600000 J/kg per kWh/kg = 0.0006461111111111 kWh/kg
Both units are defined exactly, so the factor is exact. BTU per Pound definition: BTU per pound; Kilowatt-hour per Kilogram definition: kilowatt-hour per kilogram.
Worked examples
- A reading of 144 BTU/lb converts to 0.09304 kWh/kg.
144 BTU/lb × 0.0006461111111 = 0.09304 kWh/kg - A value of 1000 BTU/lb is 0.6461111111 kWh/kg.
1000 BTU/lb × 0.0006461111111 = 0.6461111111 kWh/kg
