FAQ

What is the conversion factor from ft³/lb to m³/kg?
1 ft³/lb equals 0.06242796 m³/kg. To convert, multiply the value in cubic feet per pound by 0.06242796.
How do I convert 1 ft³/lb to m³/kg?
1 ft³/lb = 0.062428 m³/kg. For any value, multiply by 0.06242796.
How do I convert m³/kg back to ft³/lb?
Divide by the same factor — or equivalently, multiply by 16.01846. So 1 m³/kg = 16.0185 ft³/lb.
When would I need to convert cubic foot per pound to cubic metre per kilogram?
Specific-volume conversions between ft³/lb and m³/kg arise in steam-table lookups, compressible-flow analysis, and thermodynamic state-point work. Specific volume is the reciprocal of density and must not be confused with it — m³/kg and ft³/lb appear directly in property tables and equation-of-state solvers.
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).
