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.
