About Converting Cubic foot per Minutes to Liter per Hours
Cubic foot per Minutes 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. Cubic foot per Minutes is most often used for the standard unit for rating hvac airflow, compressed-air equipment output, and fan/blower performance.
Formula
liter per hours = cubic foot per minutes × 1699.01079552
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic foot per minutes equals 0.0004719474432 base units, and 1 liter per hours equals 2.777778e-7 base units, so dividing one by the other gives the direct cubic foot per minutes-to-liter per hours factor of 1699.01079552.
Simple example
1 ft3/min × 1699.010796 = 1,699.010796 L/h
1 cubic foot per minutes = 1,699.010796 liter per hours.
Real-world example
60 ft3/min × 1699.010796 = 101,940.6477 L/h
60 cubic foot per minutes = 101,940.6477 liter per hours.
Conversion table
| Cubic foot per Minutes (ft3/min) | Liter per Hours (L/h) |

What is a cubic foot per minutes?
Cubic foot per Minutes (ft3/min) measures volumetric flow rate. One cubic foot of volume passing a point every minute. It is classified as a US customary flow-rate unit.
What is a liter per hours?
Liter per Hours (L/h) is a unit of flow rate.
Is the cubic foot per minutes to liter per hours conversion exact?
Yes. Both cubic foot per minutes and liter per hours are defined by fixed standards rather than physical artifacts, so the factor of 1699.010796 used above is exact to as many digits as you choose to display.

United States, and widely recognized internationally in HVAC and compressed-air equipment specifications
What's the difference between volumetric and mass flow rate?
Volumetric flow rate measures the volume of fluid passing a point per unit time (for example, liters per second). Mass flow rate measures the mass instead. For a fluid of constant density the two are directly proportional, but for compressible fluids like gases, mass flow is often the more meaningful quantity.
