How the conversion works

Multiply by 0.0630901964 to go from US gallon per minute to liter 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? liter per second to US gallon per minute — 1 L/s = 15.85032314 gpm.
