Kilocalorie (IT) per kilogram quick reference
| Kilocalorie (IT) per kilogram | Megajoule per kilogram | BTU per pound | Joule per kilogram |
|---|---|---|---|
| 1 kcal/kg | = 0.0041868 MJ/kg | = 1.8 BTU/lb | = 4186.8 J/kg |
| 10 kcal/kg | = 0.041868 MJ/kg | = 18 BTU/lb | = 41868 J/kg |
| 100 kcal/kg | = 0.41868 MJ/kg | = 180 BTU/lb | = 418680 J/kg |
| 1000 kcal/kg | = 4.1868 MJ/kg | = 1800 BTU/lb | = 4186800 J/kg |
Where the kilocalorie (IT) per kilogram fits
The next smaller fuel energy per mass unit is the watt-hour per kilogram (Wh/kg). 1 kcal/kg = 1.163 Wh/kg, and 1 Wh/kg ≈ 0.8598452279 kcal/kg.
The next larger fuel energy per mass unit is the megajoule per kilogram (MJ/kg). 1 kcal/kg = 0.0041868 MJ/kg, and 1 MJ/kg ≈ 238.8458966 kcal/kg.
