About Converting Cubic foot per Hours to Liter per Seconds
Cubic foot per Hours and Liter per Seconds 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. Both are volumetric flow rate units.
Formula
liter per seconds = cubic foot per hours × 0.00786579072
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic foot per hours equals 0.00000786579072 base units, and 1 liter per seconds equals 0.001 base units, so dividing one by the other gives the direct cubic foot per hours-to-liter per seconds factor of 0.00786579072.
Simple example
1 ft3/h × 0.00786579072 = 0.0078657907 L/s
1 cubic foot per hours = 0.0078657907 liter per seconds.
Real-world example
60 ft3/h × 0.00786579072 = 0.4719474432 L/s
60 cubic foot per hours = 0.4719474432 liter per seconds.

Understanding the Cubic foot per Hours (ft3/h)
Volumetric flow rate.
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
Liter per Seconds — sources
- BIPM SI Brochure — Litre and second as accepted units used together to express flow rate.

Frequently asked questions
How many liter per seconds are in 1 cubic foot per hours?
1 cubic foot per hours equals 0.0078657907 liter per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cubic foot per hours to liter per seconds?
Multiply the cubic foot per hours value by 0.00786579072. The converter above does this instantly to whatever precision you set.
How do I convert liter per seconds back to cubic foot per hours?
Use the reverse factor: 1 liter per seconds equals 127.1328002 cubic foot per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic foot per hours?
Cubic foot per Hours (ft3/h) is a unit of flow rate.
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.
Is the cubic foot per hours to liter per seconds conversion exact?
Yes. Both cubic foot per hours and liter per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.00786579072 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.
