FAQ

What is the conversion factor from kWh/kg to BTU/lb?
1 kWh/kg equals 1547.721 BTU/lb. To convert, multiply the value in kilowatt-hours per kilogram by 1547.721.
How do I convert 1 kWh/kg to BTU/lb?
1 kWh/kg = 1547.72 BTU/lb. For any value, multiply by 1547.721.
How do I convert BTU/lb back to kWh/kg?
Divide by the same factor — or equivalently, multiply by 0.0006461112. So 1 BTU/lb = 0.000646111 kWh/kg.
When would I need to convert kilowatt-hour per kilogram to British thermal unit per pound?
Specific-energy conversions between kWh/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).
