About Converting Cubic foot per Seconds to Cubic Meters per Millisecond
Cubic foot per Seconds and Cubic Meter per Millisecond 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 Seconds is most often used for the standard unit used by the us geological survey for reporting river and stream discharge at gauging stations.
Formula
cubic meters per millisecond = cubic foot per seconds × 0.000028316846592
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic foot per seconds equals 0.028316846592 base units, and 1 cubic meter per millisecond equals 1000 base units, so dividing one by the other gives the direct cubic foot per seconds-to-cubic meter per millisecond factor of 0.000028316846592.
Simple example
1 ft3/s × 0.00002831684659 = 0.0000283168 m3/ms
1 cubic foot per seconds = 0.0000283168 cubic meters per millisecond.
Real-world example
60 ft3/s × 0.00002831684659 = 0.0016990108 m3/ms
60 cubic foot per seconds = 0.0016990108 cubic meters per millisecond.

Frequently asked questions
How many cubic meters per millisecond are in 1 cubic foot per seconds?
1 cubic foot per seconds equals 0.0000283168 cubic meters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert cubic foot per seconds to cubic meter per millisecond?
Multiply the cubic foot per seconds value by 0.00002831684659. The converter above does this instantly to whatever precision you set.
How do I convert cubic meter per millisecond back to cubic foot per seconds?
Use the reverse factor: 1 cubic meter per millisecond equals 35,314.66672 cubic foot per seconds. You can also use the swap control in the converter above to flip the direction instantly.
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.
What is a cubic meter per millisecond?
Cubic Meter per Millisecond (m3/ms) is a unit of flow rate.
Is the cubic foot per seconds to cubic meter per millisecond conversion exact?
Yes. Both cubic foot per seconds and cubic meter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.00002831684659 used above is exact to as many digits as you choose to display.
Where is the cubic foot per seconds still used today?
United States
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.
