How to convert cubic meter per second to gallon per minute
Enter your flow rate in cubic meter per second and get the equivalent in gallon per minute instantly. Key reference points: a typical shower head flows at about 9.5 liters per minute (2.5 GPM), a garden hose at about 37.8 L/min (10 GPM), and residential water supply pipes deliver 7-12 GPM.
Cubic meters per second (m3/s, m³/s or meters cubed per second) is the metric standard for large flow measurements; gallons per minute (GPM, gal/min) is the US standard for pump ratings, pool filtration and plumbing specifications. To convert m3/s to GPM, multiply by approximately 15850. The reverse (GPM to m3/s, gpm to cubic meters per second, or gpm to cubic meter per second) divides GPM by 15850.

Frequently asked questions
1 cubic meter per second equals 15850.3 gallon per minute.
Multiply by 15850.3. For example, 5 m³/s = 79251.6 GPM.
Multiply m3/s by 15850 to get US GPM. For example, 0.001 m3/s × 15850 = 15.85 GPM and 1 m3/s = 15,850 GPM. Going the other way, divide GPM by 15850 to get m3/s - so 1000 GPM ÷ 15850 = 0.0631 m3/s.
1 gallon per minute equals 0.0000630902 cubic meter per second.
100 cubic meter per second equals 1585032 gallon per minute.
