How many GPM is 1 liter per minute?

1 liter per minute equals 0.2641720524 US gallons per minute. For quick mental math, multiply L/min by roughly 0.264 to get GPM.

How do I convert L/min to GPM manually?

Multiply the L/min value by 0.2641720524. For example, 10 L/min × 0.2641720524 = 2.6417 GPM.

What is the difference between L/min and GPM?

L/min (liters per minute) is a metric flow rate unit used widely in engineering and science. GPM (gallons per minute) refers to US gallons per minute and is the standard flow rate unit in American plumbing, HVAC, and pump specifications.

Does this use US gallons or imperial gallons?

This converter uses US liquid gallons (1 US gal = 3.785411784 L). Imperial (UK) gallons are larger — 1 imperial gal ≈ 4.546 L. If you need imperial GPM, the factor is 1 L/min ≈ 0.2199692 imperial GPM.

What flow rates are typical for household fixtures?

A standard kitchen faucet flows at about 8–9 L/min (2.1–2.4 GPM). A showerhead typically runs 6–9 L/min (1.6–2.4 GPM). A toilet fill valve refills at roughly 6–8 L/min (1.6–2.1 GPM).
