Liters per second to cubic meters per hour
Type a value in L/s to get it in m³/h instantly.
36m³/h
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.
Convert the other way: m³/h to L/s
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 m³/h
To convert liters per second to cubic meters per hour, multiply by 3.6.
Example: 10 L/s × 3.6 = 36 m³/h.
In the other direction, 1 m³/h = 0.277778 L/s.

About these units
Liters per second (L/s)
Liters per second is the SI-friendly flow unit, used for pumps, rivers and large supplies.
Cubic meters per hour (m³/h)
A cubic meter per hour is 1,000 liters per hour. Water meters and industrial pumps use it.
