Flow Rate Converter (GPM / LPM / m³/h)
Formula
LPM = GPM x 3.78541 | m³/h = GPM x 0.227125 | CFS = GPM x 0.002228 | GPH = GPM x 60
Frequently Asked Questions
How many liters per minute is 1 GPM?
One US gallon per minute equals approximately 3.785 liters per minute (LPM). This conversion is critical in plumbing, irrigation, and water treatment applications.
What is a typical household water flow rate?
A typical US household faucet flows at 1.5-2.2 GPM (5.7-8.3 LPM), a shower at 2.0-2.5 GPM (7.6-9.5 LPM), and a garden hose at 5-10 GPM (19-38 LPM).
What is CFS and when is it used?
CFS (cubic feet per second) is used to measure large-scale water flow such as rivers, streams, and stormwater systems. One CFS equals approximately 448.8 GPM or 28.3 liters per second.
