Convert Liters/second to Cubic meters/hour (L/s to m³/h)
1 L/s = 3.6 m³/h. Convert liters/second to cubic meters/hour with the exact factor, a common-values table and a free converter.
Conversion factor
m³/h = L/s × 3.6
1 L/s = 3.6 m³/h
Multiply by 3.6 m³/h to go from liters/second to cubic meters/hour, or divide by it to come back. The factor and every value below are computed by the same converter that runs at /convert, so this page and the tool cannot disagree.
L/s to m³/h table
| Liters/second (L/s) | Cubic meters/hour (m³/h) |
|---|---|
| 1 L/s | 3.6 m³/h |
| 2 L/s | 7.2 m³/h |
| 5 L/s | 18 m³/h |
| 10 L/s | 36 m³/h |
| 20 L/s | 72 m³/h |
| 50 L/s | 180 m³/h |
| 100 L/s | 360 m³/h |
Every figure is computed at build time by the site’s own converter from the flow rate unit registry. For a value that is not listed, put it into the interactive converter.
Frequently asked questions
How many cubic meters/hour are in one liter/second?
One liter/second is 3.6 m³/h, so 100 L/s is 360 m³/h.
What is the formula to convert liters/second to cubic meters/hour?
m³/h = L/s × 3.6. Multiply the value in liters/second by 3.6 to get cubic meters/hour.
How do I convert cubic meters/hour back to liters/second?
L/s = m³/h × 0.277777778, so 1 m³/h is 0.277777778 L/s. The m³/h to L/s page carries the same table in that direction.
