About Gram per Kilowatt-Hour (g/kWh)
The international standard SI-metric brake-specific fuel consumption (BSFC) unit, representing grams of fuel consumed per kilowatt-hour of shaft work (toBase = 3.6ร10โน / value).
History: Adopted worldwide by ISO and SAE as the definitive engine efficiency metric.
Common Uses: Automotive and industrial engine efficiency maps, generator fuel economy specs, marine propulsion.
About Joule per Kilogram (J/kg)
The SI unit of specific energy and fuel heating value, representing 1 joule of energy liberated or consumed per kilogram of mass.
History: Adopted in SI physical chemistry as the fundamental quotient of energy divided by mass.
Common Uses: Calorific value of solid fuels, battery gravimetric energy density, specific kinetic energy.
โ Frequently Asked Questions
What is the formula to convert Gram per Kilowatt-Hour to Joule per Kilogram?
The formula is: J/kg = C / (g/kWh). Gram per Kilowatt-Hour represents reciprocal fuel consumption (fuel per energy). Converting to Joule per Kilogram inverts the ratio through canonical base units.
How do I convert 1 g/kWh to J/kg manually?
To convert 1 g/kWh to J/kg: apply the formula J/kg = C / (g/kWh). Substituting gives: Converted via inverse base energy relation = 3600000000 J/kg.
