About Converting Liter per Seconds to Liter per Hours
Liter per Seconds and Liter 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 most often used for municipal water supply and treatment plant flow rates.
Formula
liter per hours = liter per seconds × 3600
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 liter per hours equals 2.777778e-7 base units, so dividing one by the other gives the direct liter per seconds-to-liter per hours factor of 3600.
Simple example
1 L/s × 3600 = 3,600 L/h
1 liter per seconds = 3,600 liter per hours.
Real-world example
60 L/s × 3600 = 216,000 L/h
60 liter per seconds = 216,000 liter per hours.
Conversion table
| Liter per Seconds (L/s) | Liter per Hours (L/h) |
|---|---|
| 0.1 L/s | 360 L/h |
| 1 L/s | 3,600 L/h |
| 10 L/s | 36,000 L/h |
| 60 L/s | 216,000 L/h |
| 100 L/s | 360,000 L/h |
| 1,000 L/s | 3,600,000 L/h |
Reverse conversion: Liter per Hours to Liter per Seconds
1 L/h × 0.0002777777778 = 0.0002777778 L/s
1 liter per hours = 0.0002777778 liter per seconds.
liter per seconds = liter per hours × 0.000277777777778

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

Frequently asked questions
How many liter per hours are in 1 liter per seconds?
1 liter per seconds equals 3,600 liter per hours, using the exact defined conversion factor rather than an estimate.
How do I convert liter per seconds to liter per hours?
Multiply the liter per seconds value by 3600. The converter above does this instantly to whatever precision you set.
How do I convert liter per hours back to liter per seconds?
Use the reverse factor: 1 liter per hours equals 0.0002777778 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 liter per hours?
Liter per Hours (L/h) is a unit of flow rate.
Is the liter per seconds to liter per hours conversion exact?
Yes. Both liter per seconds and liter per hours are defined by fixed standards rather than physical artifacts, so the factor of 3600 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?
