About Converting Cubic feet per Millisecond to Cubic foot per Seconds
Cubic foot 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 = cubic feet per millisecond × 1000
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic foot per millisecond equals 28.316846592 base units, and 1 cubic foot per seconds equals 0.028316846592 base units, so dividing one by the other gives the direct cubic foot per millisecond-to-cubic foot per seconds factor of 1000.
Simple example
1 ft3/ms × 1000 = 1,000 ft3/s
1 cubic foot per millisecond = 1,000 cubic foot per seconds.
Real-world example
60 ft3/ms × 1000 = 60,000 ft3/s
60 cubic feet per millisecond = 60,000 cubic foot per seconds.
Conversion table
| Cubic foot per Millisecond (ft3/ms) | Cubic foot per Seconds (ft3/s) |
|---|---|
| 0.1 ft3/ms | 100 ft3/s |
| 1 ft3/ms | 1,000 ft3/s |
| 10 ft3/ms | 10,000 ft3/s |
| 60 ft3/ms | 60,000 ft3/s |
| 100 ft3/ms | 100,000 ft3/s |
| 1,000 ft3/ms | 1,000,000 ft3/s |
Reverse conversion: Cubic foot per Seconds to Cubic foot per Millisecond
1 ft3/s × 0.001 = 0.001 ft3/ms
1 cubic foot per seconds = 0.001 cubic feet per millisecond.
cubic feet per millisecond = cubic foot per seconds × 0.001

Frequently asked questions
How many cubic foot per seconds are in 1 cubic foot per millisecond?
1 cubic foot per millisecond equals 1,000 cubic foot per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cubic foot per millisecond to cubic foot per seconds?
Multiply the cubic foot per millisecond value by 1000. The converter above does this instantly to whatever precision you set.
How do I convert cubic foot per seconds back to cubic foot per millisecond?
Use the reverse factor: 1 cubic foot per seconds equals 0.001 cubic feet per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic foot per millisecond?
Cubic foot per Millisecond (ft3/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 cubic foot per millisecond to cubic foot per seconds conversion exact?
Yes. Both cubic foot per millisecond and cubic foot per seconds are defined by fixed standards rather than physical artifacts, so the factor of 1000 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.
