FAQ

What is the conversion factor from GJ/kg to kcal/lb?
1 GJ/kg equals 108411.1 kcal/lb. To convert, multiply the value in gigajoules per kilogram by 108411.1.
How do I convert 1 GJ/kg to kcal/lb?
1 GJ/kg = 108411 kcal/lb. For any value, multiply by 108411.1.
How do I convert kcal/lb back to GJ/kg?
Divide by the same factor — or equivalently, multiply by 9.224144e-6. So 1 kcal/lb = 9.22414e-6 GJ/kg.
When would I need to convert gigajoule per kilogram to kilocalorie per pound?
Specific-energy conversions between GJ/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).
