Cubic metres per hour to US gallons per minute
1 cubic metre per hour = 4.4029 US gallons per minute · 1 gpm (US) = 0.22712 m³/h
1 cubic metre per hour = 4.4029 US gallons per minute
How it’s calculated
gpm (US) = m³/h × 4.402867539
- Multiply the value in cubic metres per hour by 4.402867539.
- To go back, divide by 4.402867539 (or multiply by 0.227124707).
- 1 m³/h = 4.402867539 gpm (US) · 1 gpm (US) = 0.227124707 m³/h

Find the conversion factor
By definition 1 m³/h = 0.000277777777777778 m³/s and 1 gpm (US) = 0.0000630901964 m³/s, so 1 gpm (US) = 0.22712470704 m³/h. Source: BIPM SI Brochure (9th ed.) (SI prefixes and accepted units); NIST SP 811 / Handbook 44.
Multiply by the factor written as a fraction
Put m³/h in the denominator so it cancels, leaving gpm (US).
