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.

Recommended

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