GPM to L/min: Convert gallons per minute to liters per minute

Answer
3.78541 L/min = 1 GPM

1 GPM = 3.78541 L/min. To convert gallons per minute to liters per minute, multiply by 3.785411784. To go back, multiply by 0.2641720524 (or divide by 3.785411784). GPM (US gallons per minute) rates pumps, wells, faucets and showerheads.
