About Liters per Minute and Gallons per Minute (US)

Liters per minute (LPM) and gallons per minute (GPM) are the two most common flow rate units worldwide. LPM is used in metric countries for pumps, irrigation, and industrial equipment; GPM is the US standard. 1 LPM = 0.2642 GPM.

Common Uses for This Conversion

Pump sizing and selection, irrigation system design, pool and spa circulation, fire suppression system calculations, and comparing imported equipment specs.

💡Did You Know?

A typical household washing machine uses about 50–60 LPM (13–16 GPM) of water during a wash cycle.

Frequently Asked Questions

100 LPM = 26.42 GPM. Multiply any LPM value by 0.2642 to get GPM. This conversion factor comes from the US liquid gallon being exactly 3.785411784 liters.
10 GPM = 37.85 LPM. Multiply any GPM value by 3.7854 to get LPM. A 10 GPM pump is a common size for residential well systems in the US.
Yes. 1 US gallon per minute = 3.785411784 liters per minute exactly. The UK gallon is larger (4.54609 L), so 1 UK GPM = 4.546 LPM — always confirm which gallon standard is used on pump datasheets.
Typical drip irrigation emitters deliver 0.5–2 GPM (1.9–7.6 LPM) per zone. A full field system may need 20–50 GPM (76–189 LPM) depending on emitter count. Use our LPM to GPM converter to match your metric pump to US drip emitter specs.
