How to convert cubic feet per pound to cubic meters per kilogram
Specific volume is the reciprocal of density, but this tool converts specific-volume units only. A gas value still depends on temperature and pressure.
Use x for the value in ft³/lb, b for the intermediate value in m³/kg, and y for the result in m³/kg.
m³/kg = ft³/lb × 0.062427960576144616
Worked examples
10 ft³/lb ≈ 0.624279605761 m³/kg
Step 1: (10 × 0.0624279605761) ≈ 0.624279605761 m³/kg.
Step 2: 0.624279605761 ÷ 1 ≈ 0.624279605761 m³/kg.20 ft³/lb ≈ 1.24855921152 m³/kg
Step 1: (20 × 0.0624279605761) ≈ 1.24855921152 m³/kg.
Step 2: 1.24855921152 ÷ 1 ≈ 1.24855921152 m³/kg.
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
About Cubic feet per pound
