Fuel Heating Value - Mass Converter
Convert fuel heating value by mass (the energy released per unit mass of fuel) between joules per kilogram, BTU per pound and related units.
Written by Rahman · Last reviewed
Quick answer
This converts specific energy: energy released per unit mass of fuel. The SI unit is joules per kilogram: one megajoule per kilogram is a million, one calorie per gram is 4,186.8 J/kg and one BTU per pound is 2,326 J/kg. Petrol carries roughly 46 MJ/kg, while a lithium-ion cell stores closer to 0.9 MJ/kg.

About the Fuel Heating Value - Mass Converter
Fuel heating value by mass measures how much energy is released per unit of fuel mass, for example joules per kilogram or BTU per pound. It describes the energy content, or calorific value, of a fuel.
This converter is used in combustion engineering and energy analysis when comparing fuels of different types.
Frequently Asked Questions
What does fuel heating value by mass measure?
⌄
It measures the energy released per unit of fuel mass, also known as the specific energy or calorific value of the fuel.
What is the SI unit?
⌄
The SI unit is the joule per kilogram (J/kg). Megajoules per kilogram is common for practical fuel comparisons.
How is this different from fuel heating value by volume?
⌄
This converter uses energy per unit mass, while the volume version uses energy per unit volume, useful when fuels have different densities.
