FAQ

What is the conversion factor from kcal/lb to BTU/lb?
1 kcal/lb equals 3.965668 BTU/lb. To convert, multiply the value in kilocalories per pound by 3.965668.
How do I convert 1 kcal/lb to BTU/lb?
1 kcal/lb = 3.96567 BTU/lb. For any value, multiply by 3.965668.
How do I convert BTU/lb back to kcal/lb?
Divide by the same factor — or equivalently, multiply by 0.2521643. So 1 BTU/lb = 0.252164 kcal/lb.
When would I need to convert kilocalorie per pound to British thermal unit per pound?
Specific-energy conversions between kcal/lb 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).
