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 btu (it) per pound 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 btu (it) per pound equals 2,326 joules per kilogram. Enter your value above — reciprocal units are handled correctly in both directions.
