1 cal (IT)/g = 4186.8 J/kg
1 J/kg = 0.0002388459 cal (IT)/g
To convert calorie (it) per gram to joule per kilogram, multiply by 4186.8.
To convert joule per kilogram to calorie (it) per gram, multiply by 0.0002388459.
Example: convert 10 cal (IT)/g to J/kg
10 × 4186.8 = 41868 J/kg
About these units
Short background on the units used in this conversion.
Joule per Kilogram (J/kg)
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.
Frequently asked questions
How do I convert calorie (it) per gram to joule per kilogram?
Fuel efficiency uses inverse math when crossing energy-per-mass (or volume) and mass-per-energy (or volume-per-energy) units. One calorie (it) per gram equals 4,186.8 joules per kilogram. Enter your value above — reciprocal units are handled correctly in both directions.
