How it is calculated
m³/h = L/s × 3.6
Multiply the value in liters per second by 3.6 to get cubic meters per hour.
Example
To convert 25 L/s to cubic meters per hour: 25 × 3.6 = 90 m³/h.

About the units
- Liter per second
- One liter passing each second, 0.001 m³/s, used in ventilation design and drainage networks.
- Cubic meter per hour
- One cubic meter passing each hour, 1/3600 m³/s, the usual unit for water pumps and ventilation.
Limits and caveats
- Results are rounded for display and computed with the browser's floating point precision (about 15 significant digits).
- Both unit factors are exact by their official definitions.
Questions about this tool
How many cubic meters per hour are in one liter per second?
1 L/s = 3.6 m³/h exactly.
How do I convert liters per second to cubic meters per hour?
Use m³/h = L/s × 3.6. For example, 25 L/s = 90 m³/h.
How many liters per second are in one cubic meter per hour?
1 m³/h = 0.277778 L/s.
How do I convert liters per minute to US gallons per minute?
One US gallon per minute is exactly 3.785411784 L/min, so divide the liters figure by 3.785411784. For example, 20 L/min is about 5.28 US gpm.
What does CFM mean on AC units and fans?
CFM stands for cubic feet per minute and describes how much air a unit moves. One CFM equals 1.69901079552 cubic meters per hour or 0.4719474432 liters per second.
