FAQ

What is the conversion factor from cal/kg to kWh/kg?
1 cal/kg equals 1.162222e-6 kWh/kg. To convert, multiply the value in calories per kilogram by 1.162222e-6.
How do I convert 1 cal/kg to kWh/kg?
1 cal/kg = 1.16222e-6 kWh/kg. For any value, multiply by 1.162222e-6.
How do I convert kWh/kg back to cal/kg?
Divide by the same factor — or equivalently, multiply by 860420.7. So 1 kWh/kg = 860421 cal/kg.
When would I need to convert calorie per kilogram to kilowatt-hour per kilogram?
Specific-energy conversions between cal/kg and kWh/kg 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).
