FAQ

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