Short background on the units used in this conversion.
The cubic meter per second (m³/s) is the SI unit of volumetric flow rate — volume passing a cross-section per unit time.
Cubic meters per second rate large pipelines, hydrology, and industrial process flows in metric engineering.
Gallon (US) per minute (GPM) equals 6.30902×10⁻⁵ m³/s using the US liquid gallon of 3.785411784 L.
GPM is the standard US plumbing and pump rating — distinct from the larger UK imperial gallon.
GPM = m³/s × 15,850.3231414889m³/s = GPM × 0.0000630902, using the same exact factors as this converter.Jump to any flow conversion starting from cubic meter per second — including the reverse direction and every other unit in our dataset.
