Frequently Asked Questions
How do I convert liters per minute to US gallons per minute?
Multiply the L/min value by 0.2641720524. For example, 15 L/min × 0.2641720524 = 3.963 gpm.
Is this the US gallon or the UK imperial gallon?
This page uses the US gallon (3.785411784 L). The UK imperial gallon is larger, so a UK-sourced gpm figure would need a different conversion factor.
Where does this conversion come up?
Pump specifications, faucet and showerhead flow-rate ratings, and irrigation equipment often list flow in one system, and comparing US and metric equipment specs requires converting between them.

A good measuring tool marked in both L/min and gpm removes the guesswork at the point of use.
