How the conversion works

Multiply by 0.0000630901964 to go from US gallon per minute to cubic meter per second, or divide by it to go back. Every conversion on this site routes through the SI value (m³/s) rather than a table of pairwise factors, so a round-trip returns exactly what you started with.

Going the other way? cubic meter per second to US gallon per minute — 1 m³/s = 15,850.32314 gpm.
