About Converting Cubic yards per Millisecond to Cubic foot per Seconds
Cubic yard 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 yards per millisecond × 27000
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic yard per millisecond equals 764.554857984 base units, and 1 cubic foot per seconds equals 0.028316846592 base units, so dividing one by the other gives the direct cubic yard per millisecond-to-cubic foot per seconds factor of 27000.
Simple example
1 yd3/ms × 27000 = 27,000 ft3/s
1 cubic yard per millisecond = 27,000 cubic foot per seconds.
Real-world example
60 yd3/ms × 27000 = 1,620,000 ft3/s
60 cubic yards per millisecond = 1,620,000 cubic foot per seconds.

Frequently asked questions
How many cubic foot per seconds are in 1 cubic yard per millisecond?
1 cubic yard per millisecond equals 27,000 cubic foot per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cubic yard per millisecond to cubic foot per seconds?
Multiply the cubic yard per millisecond value by 27000. The converter above does this instantly to whatever precision you set.
How do I convert cubic foot per seconds back to cubic yard per millisecond?
Use the reverse factor: 1 cubic foot per seconds equals 0.000037037 cubic yards per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic yard per millisecond?
Cubic yard per Millisecond (yd3/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 yard per millisecond to cubic foot per seconds conversion exact?
Yes. Both cubic yard per millisecond and cubic foot per seconds are defined by fixed standards rather than physical artifacts, so the factor of 27000 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.
