Type a value in L/s to get it in GPM instantly.
158.5GPM
That's 2× as much flow as a pool pump, while a fire hose is 1.6× faster. At that rate a 150-liter bathtub fills in about 0.25 minutes.
What it means
How much flow is that?
Reference flows are typical values. A mains tap varies a lot with pressure and plumbing.
The math
How to convert L/s to GPM
