tool.fuel-conversion Calculator
Converts fuel quantities between litres, gallons, kilograms (for LPG and jet fuel), and energy content in MJ and kWh. Jet fuel and LPG are typically priced by weight rather than volume — this bridges the two systems.
Inputs
Liters
Reference formula or conversion factor shown for context.
Energy Mj L
Mass per unit volume (kg/m³). Water: 1,000. Air: 1.225. Steel: 7,850. Affects buoyancy, flow, and structural loads.
Efficiency
Useful output divided by total input, as a percentage. 100% is impossible due to losses (heat, friction, resistance).
Price L
Reference formula or conversion factor shown for context.
Results
total energy (MJ)
The combined total across all inputs and components.
useful energy (MJ)
Sample size or count used in the calculation.
total energy (kWh)
The combined total across all inputs and components.
useful energy (kWh)
Sample size or count used in the calculation.
fuel cost
The total monetary cost computed for the given inputs.
energy cost per kWh
The total monetary cost computed for the given inputs.
