How to convert liters per second to cubic meters per hour
m³/h = L/s × 3.6Multiply the value in liters per second by 3.6. To go the other way, multiply by 0.2777777778 (or divide by 3.6).
A liter per second is larger than a cubic meter per hour: one liter per second contains 3.6 cubic meters per hour.
Worked examples
- 1 liter per second1 L/s × 3.6 = 3.6 m³/h
- 5 liters per second5 L/s × 3.6 = 18 m³/h
- 10 liters per second10 L/s × 3.6 = 36 m³/h
- 20 liters per second20 L/s × 3.6 = 72 m³/h
- 100 liters per second100 L/s × 3.6 = 360 m³/h

About the units
Liter per second (L/s)
The liter per second (L/s) is a unit of volumetric flow rate in the metric system. One liter per second equals 0.001 cubic meters per second (m³/s).
Cubic meter per hour (m³/h)
Common rating unit for pumps and ventilation outside the US. One cubic meter per hour equals 0.0002777777778 cubic meters per second (m³/s).
Frequently asked questions
How many cubic meters per hour are in one liter per second?
There are 3.6 cubic meters per hour in one liter per second, and this value is exact by definition.
How do I convert liters per second to cubic meters per hour?
Multiply the number of liters per second by 3.6. For example, 10 L/s × 3.6 = 36 m³/h.
How many liters per second are in one cubic meter per hour?
One cubic meter per hour equals 0.2777777778 liters per second. That is the reverse factor, 1 ÷ 3.6.
What is 10 liters per second in cubic meters per hour?
10 L/s = 36 m³/h.
Is this L/s to m³/h converter accurate?
Yes. Both units are defined exactly in terms of SI units, so the conversion factor is exact; results are shown to 12 significant figures by default and you can change precision in the converter. Calculations run in your browser using the same tested engine that generated this page.
