FAQ

What is the conversion factor from Wh/kg to cal/kg?
1 Wh/kg equals 860.4207 cal/kg. To convert, multiply the value in watt-hours per kilogram by 860.4207.
How do I convert 1 Wh/kg to cal/kg?
1 Wh/kg = 860.421 cal/kg. For any value, multiply by 860.4207.
How do I convert cal/kg back to Wh/kg?
Divide by the same factor — or equivalently, multiply by 0.001162222. So 1 cal/kg = 0.00116222 Wh/kg.
When would I need to convert watt-hour per kilogram to calorie per kilogram?
Specific-energy conversions between Wh/kg and cal/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).
