FAQ

What is the conversion factor from kJ/kg to kcal/lb?
1 kJ/kg equals 0.1084111 kcal/lb. To convert, multiply the value in kilojoules per kilogram by 0.1084111.
How do I convert 1 kJ/kg to kcal/lb?
1 kJ/kg = 0.108411 kcal/lb. For any value, multiply by 0.1084111.
How do I convert kcal/lb back to kJ/kg?
Divide by the same factor — or equivalently, multiply by 9.224144. So 1 kcal/lb = 9.22414 kJ/kg.
When would I need to convert kilojoule per kilogram to kilocalorie per pound?
Specific-energy conversions between kJ/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).
