FAQ

What is the conversion factor from kcal/kg to Wh/kg?
1 kcal/kg equals 1.162222 Wh/kg. To convert, multiply the value in kilocalories per kilogram by 1.162222.
How do I convert 1 kcal/kg to Wh/kg?
1 kcal/kg = 1.16222 Wh/kg. For any value, multiply by 1.162222.
How do I convert Wh/kg back to kcal/kg?
Divide by the same factor — or equivalently, multiply by 0.8604207. So 1 Wh/kg = 0.860421 kcal/kg.
When would I need to convert kilocalorie per kilogram to watt-hour per kilogram?
Specific-energy conversions between kcal/kg and Wh/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).
