Short background on the units used in this conversion.
The joule per kilogram (J/kg) is the SI unit of fuel efficiency on a mass basis — useful energy per unit fuel mass.
Joules per kilogram compare heating values and energy content of fuels, propellants, and biomass on a mass basis.
Calorie (IT) per gram equals 4186.8 J/kg — numerically the specific energy of water near room temperature.
Calories (IT) per gram express food and fuel energy content in metric mass-based tables.
1 joule per kilogram = 0.0002388459 calories (IT) per gram1 calorie (it) per gram = 4,186.8 joules per kilogram. IT and thermochemical variants are kept separate.Jump to any fuel efficiency-mass conversion starting from joule per kilogram — including the reverse direction and every other unit in our dataset.
