FAQ

What is the conversion factor from kcal/kg to BTU/lb?
1 kcal/kg equals 1.798796 BTU/lb. To convert, multiply the value in kilocalories per kilogram by 1.798796.
How do I convert 1 kcal/kg to BTU/lb?
1 kcal/kg = 1.7988 BTU/lb. For any value, multiply by 1.798796.
How do I convert BTU/lb back to kcal/kg?
Divide by the same factor — or equivalently, multiply by 0.5559274. So 1 BTU/lb = 0.555927 kcal/kg.
When would I need to convert kilocalorie per kilogram to British thermal unit per pound?
Specific-energy conversions between kcal/kg and BTU/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).
