About Converting Liters per Millisecond to Cubic foot per Seconds
Liter per Millisecond and Cubic foot 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
cubic foot per seconds = liters per millisecond × 35.3146667215
This factor comes from each unit's defined relationship to the category's base unit: 1 liter per millisecond equals 1 base unit, and 1 cubic foot per seconds equals 0.028316846592 base units, so dividing one by the other gives the direct liter per millisecond-to-cubic foot per seconds factor of 35.3146667215.
Simple example
1 L/ms × 35.31466672 = 35.31466672 ft3/s
1 liter per millisecond = 35.31466672 cubic foot per seconds.
Real-world example
60 L/ms × 35.31466672 = 2,118.880003 ft3/s
60 liters per millisecond = 2,118.880003 cubic foot per seconds.

Frequently asked questions
How many cubic foot per seconds are in 1 liter per millisecond?
1 liter per millisecond equals 35.31466672 cubic foot per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert liter per millisecond to cubic foot per seconds?
Multiply the liter per millisecond value by 35.31466672. The converter above does this instantly to whatever precision you set.
How do I convert cubic foot per seconds back to liter per millisecond?
Use the reverse factor: 1 cubic foot per seconds equals 0.0283168466 liters per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a liter per millisecond?
Liter per Millisecond (L/ms) is a unit of flow rate.
What is a cubic foot per seconds?
Cubic foot per Seconds (ft3/s) measures volumetric flow rate. One cubic foot of volume passing a point every second. It is classified as a US customary flow-rate unit.
Is the liter per millisecond to cubic foot per seconds conversion exact?
Yes. Both liter per millisecond and cubic foot per seconds are defined by fixed standards rather than physical artifacts, so the factor of 35.31466672 used above is exact to as many digits as you choose to display.
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.
