How to convert US gallons per minute to cubic meters per hour
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 m³/h.
m³/h = US gal/min × 0.0000630901964 ÷ 0.0002777777777777778
Worked examples
10 US gal/min ≈ 2.2712470704 m³/h
Step 1: (10 × 0.0000630901964) ≈ 0.000630901964 m³/s.
Step 2: 0.000630901964 ÷ 0.000277777777778 ≈ 2.2712470704 m³/h.20 US gal/min ≈ 4.5424941408 m³/h
Step 1: (20 × 0.0000630901964) ≈ 0.001261803928 m³/s.
Step 2: 0.001261803928 ÷ 0.000277777777778 ≈ 4.5424941408 m³/h.
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 meters per hour
Cubic meters per hour (m³/h) measures flow under the conventions above. The base value in m³/s is (x × 0.000277777777778), where x is the numerical value in m³/h. Factors shown here are rounded for display; calculations use the stored factor.
