About Converting Liter per Seconds to Cubic Meter per Hours
Liter per Seconds and Cubic Meter per Hours both measure volumetric flow rate — how much volume passes a point over time — used to size pipes and pumps, monitor river or stream discharge, control industrial processes, and set medical infusion rates. Liter per Seconds is typically associated with common in municipal water-utility and industrial flow specifications internationally, while Cubic Meter per Hours is typically associated with standard flow-rate unit for HVAC and industrial equipment ratings internationally, outside the US.
Formula
cubic meter per hours = liter per seconds × 3.6
This factor comes from each unit's defined relationship to the category's base unit: 1 liter per seconds equals 0.001 base units, and 1 cubic meter per hours equals 0.000277777777778 base units, so dividing one by the other gives the direct liter per seconds-to-cubic meter per hours factor of 3.6.
Simple example
1 L/s × 3.6 = 3.6 m3/h
1 liter per seconds = 3.6 cubic meter per hours.
Real-world example
60 L/s × 3.6 = 216 m3/h
60 liter per seconds = 216 cubic meter per hours.
Conversion table
| Liter per Seconds (L/s) | Cubic Meter per Hours (m3/h) |
|---|---|
| 0.1 L/s | 0.36 m3/h |
| 1 L/s | 3.6 m3/h |
| 10 L/s | 36 m3/h |
| 60 L/s | 216 m3/h |
| 100 L/s | 360 m3/h |
| 1,000 L/s | 3,600 m3/h |
Reverse conversion: Cubic Meter per Hours to Liter per Seconds
3.6 m3/h × 0.2777777778 = 1 L/s
3.6 cubic meter per hours = 1 liter per seconds.
liter per seconds = cubic meter per hours × 0.277777777778

Understanding the Liter per Seconds
Liter per Seconds (L/s) measures volumetric flow rate. One liter of volume passing a point every second — used for larger flows than liter-per-minute conveniently describes. It is classified as a metric derived flow-rate unit.
Where it's used: Common in municipal water-utility and industrial flow specifications internationally
L/s vs. L/min. Both measure the same quantity at different time scales; 1 L/s equals 60 L/min. L/s is typically used for larger, continuous industrial or utility flows, while L/min suits smaller household-scale flows.
Uses of the Liter per Seconds today
- Municipal water supply and treatment plant flow rates
- Industrial process flow specifications
- Stream and river discharge measurement at moderate scales
Understanding the Cubic Meter per Hours
Cubic Meter per Hours (m3/h) measures volumetric flow rate. One cubic meter of volume passing a point every hour — a common scale for equipment and system flow ratings. It is classified as a metric derived flow-rate unit.
Where it's used: Standard flow-rate unit for HVAC and industrial equipment ratings internationally, outside the US
Uses of the Cubic Meter per Hours today
- HVAC equipment airflow and liquid-flow ratings
- Industrial pump and system flow specifications
- Building ventilation system design

Frequently asked questions
How many cubic meter per hours are in 1 liter per seconds?
1 liter per seconds equals 3.6 cubic meter per hours, using the exact defined conversion factor rather than an estimate.
How do I convert liter per seconds to cubic meter per hours?
Multiply the liter per seconds value by 3.6. The converter above does this instantly to whatever precision you set.
How do I convert cubic meter per hours back to liter per seconds?
Use the reverse factor: 1 cubic meter per hours equals 0.2777777778 liter per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a liter per seconds?
Liter per Seconds (L/s) measures volumetric flow rate. One liter of volume passing a point every second — used for larger flows than liter-per-minute conveniently describes. It is classified as a metric derived flow-rate unit.
What is a cubic meter per hours?
Cubic Meter per Hours (m3/h) measures volumetric flow rate. One cubic meter of volume passing a point every hour — a common scale for equipment and system flow ratings. It is classified as a metric derived flow-rate unit.
Is the liter per seconds to cubic meter per hours conversion exact?
Yes. Both liter per seconds and cubic meter per hours are defined by fixed standards rather than physical artifacts, so the factor of 3.6 used above is exact to as many digits as you choose to display.
What is the difference between l/s vs. l/min?
Both measure the same quantity at different time scales; 1 L/s equals 60 L/min. L/s is typically used for larger, continuous industrial or utility flows, while L/min suits smaller household-scale flows.
Where is the liter per seconds still used today?
