Conversion Formula

gpm = yd³/s × 12118.44156

About Cubic yards per second

The cubic yard per second (yd³/s) equals 0.764554857984 m³/s, a large unit used in US civil engineering for river flood-stage measurements and reservoir emergency-spillway capacity. A major dam spillway releasing water at 1 000 yd³/s could drain an Olympic pool in about 3 seconds. 1 yd³/s = 0.764554857984 m³/s ≈ 764.555 L/s ≈ 27 ft³/s.

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.
