FAQ

What is the conversion factor from kcal/kg to kcal/lb?
1 kcal/kg equals 0.4535922 kcal/lb. To convert, multiply the value in kilocalories per kilogram by 0.4535922.
How do I convert 1 kcal/kg to kcal/lb?
1 kcal/kg = 0.453592 kcal/lb. For any value, multiply by 0.4535922.
How do I convert kcal/lb back to kcal/kg?
Divide by the same factor — or equivalently, multiply by 2.204623. So 1 kcal/lb = 2.20462 kcal/kg.
When would I need to convert kilocalorie per kilogram to kilocalorie per pound?
Specific-energy conversions between kcal/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).
