FAQ

What is the conversion factor from kWh/kg to kcal/lb?
1 kWh/kg equals 390.2801 kcal/lb. To convert, multiply the value in kilowatt-hours per kilogram by 390.2801.
How do I convert 1 kWh/kg to kcal/lb?
1 kWh/kg = 390.28 kcal/lb. For any value, multiply by 390.2801.
How do I convert kcal/lb back to kWh/kg?
Divide by the same factor — or equivalently, multiply by 0.002562262. So 1 kcal/lb = 0.00256226 kWh/kg.
When would I need to convert kilowatt-hour per kilogram to kilocalorie per pound?
Specific-energy conversions between kWh/kg and kcal/lb are needed in fuel-property datasheets (HHV/LHV), thermodynamic state calculations, battery energy-density comparisons, and combustion analysis. kJ/kg is the SI standard; BTU/lb is common in US fuel specifications.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
