Flow (Volume) Converter
Volumetric flow rate is the volume of fluid passing a point per unit of time. The SI unit is the cubic metre per second (m³/s); litres per minute and gallons per minute are more common for pumps and plumbing.
1 Cubic Meter/Second = 15,850.32314 Gallon (US)/Minute
How to convert Cubic Meter/Second to Gallon (US)/Minute
One Cubic Meter/Second equals 15,850.32314 Gallon (US)/Minute, so multiply any value in m³/s by 15,850.32314 to get GPM. To convert back, divide by 15,850.32314 — or multiply by 0.0000630901964.
GPM = m³/s × 15,850.32314
Example: 25 m³/s × 15,850.32314 = 396,258.0785 GPM.
