BTU per pound quick reference
| BTU per pound | Kilojoule per kilogram | Megajoule per kilogram | Joule per kilogram |
|---|---|---|---|
| 1 BTU/lb | = 2.326 kJ/kg | = 0.002326 MJ/kg | = 2326 J/kg |
| 10 BTU/lb | = 23.26 kJ/kg | = 0.02326 MJ/kg | = 23260 J/kg |
| 100 BTU/lb | = 232.6 kJ/kg | = 0.2326 MJ/kg | = 232600 J/kg |
| 1000 BTU/lb | = 2326 kJ/kg | = 2.326 MJ/kg | = 2326000 J/kg |
Where the BTU per pound fits
The next smaller fuel energy per mass unit is the kilojoule per kilogram (kJ/kg). 1 BTU/lb = 2.326 kJ/kg, and 1 kJ/kg ≈ 0.4299226139 BTU/lb.
The next larger fuel energy per mass unit is the watt-hour per kilogram (Wh/kg). 1 BTU/lb ≈ 0.6461111111 Wh/kg, and 1 Wh/kg ≈ 1.54772141 BTU/lb.
