Convert US gallons per minute (gpm) to Cubic metres per minute (m³/min) instantly and accurately.
Conversion Formula
m³/min = gpm × 0.003785411784
About US gallons per minute
The US gallon per minute (gpm) equals 3.785411784×10⁻³/60 ≈ 6.309×10⁻⁵ m³/s, the dominant volumetric flow unit in US plumbing, HVAC, and water-treatment industries. EPA showerhead standards are set at 2.5 gpm; residential water meters size at 3/4"-1" for 5-20 gpm; municipal water-distribution design uses hundreds to thousands of gpm. 1 gpm ≈ 6.309×10⁻⁵ m³/s = 3.785 L/min.
About Cubic metres per minute
The cubic metre per minute (m³/min) equals 1/60 m³/s ≈ 1.667×10⁻² m³/s, used in large compressor and blower specifications, tunnel ventilation design, and industrial air-handling. A mine-ventilation fan may move 1 000-5 000 m³/min; an industrial rotary-screw compressor delivers 5-50 m³/min of free air. 1 m³/min = 1 000 L/min ≈ 35.31 ft³/min ≈ 264.2 US gal/min.
