How to convert US gallons per minute to cubic feet per minute
Gas volumes must refer to the same temperature and pressure. Standard and actual cubic flow rates cannot be equated without state information; US gallons here are liquid gallons.
Use x for the value in US gal/min, b for the intermediate value in m³/s, and y for the result in ft³/min.
ft³/min = US gal/min × 0.0000630901964 ÷ 0.0004719474432000001
Worked examples
10 US gal/min ≈ 1.33680555556 ft³/min
Step 1: (10 × 0.0000630901964) ≈ 0.000630901964 m³/s.
Step 2: 0.000630901964 ÷ 0.0004719474432 ≈ 1.33680555556 ft³/min.20 US gal/min ≈ 2.67361111111 ft³/min
Step 1: (20 × 0.0000630901964) ≈ 0.001261803928 m³/s.
Step 2: 0.001261803928 ÷ 0.0004719474432 ≈ 2.67361111111 ft³/min.
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 US gallons per minute
US gallons per minute (US gal/min) measures flow under the conventions above. The base value in m³/s is (x × 0.0000630901964), where x is the numerical value in US gal/min. Factors shown here are rounded for display; calculations use the stored factor.
About Cubic feet per minute
Cubic feet per minute (ft³/min) measures flow under the conventions above. The base value in m³/s is (x × 0.0004719474432), where x is the numerical value in ft³/min. Factors shown here are rounded for display; calculations use the stored factor.
