Cubic meters per hour to liters per second
Type a value in m³/h to get it in L/s instantly.
2.778L/s
That's 9.3× as much flow as a garden hose, while a pool pump is 1.8× faster. At that rate a 150-liter bathtub fills in about 0.9 minutes.
Convert the other way: L/s to m³/h
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 m³/h to L/s
To convert cubic meters per hour to liters per second, multiply by 0.277778.
Example: 10 m³/h × 0.277778 = 2.77778 L/s.
In the other direction, 1 L/s = 3.6 m³/h.
