About Converting Cubic yards per Millisecond to Gallon per Seconds
Cubic yard per Millisecond and Gallon 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
gallon per seconds = cubic yards per millisecond × 201974.025974
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 gallon per seconds equals 0.003785411784 base units, so dividing one by the other gives the direct cubic yard per millisecond-to-gallon per seconds factor of 201974.025974.
Simple example
1 yd3/ms × 201974.026 = 201,974.026 gal/s
1 cubic yard per millisecond = 201,974.026 gallon per seconds.
Real-world example
60 yd3/ms × 201974.026 = 12,118,441.56 gal/s
60 cubic yards per millisecond = 12,118,441.56 gallon per seconds.

Frequently asked questions
How many gallon per seconds are in 1 cubic yard per millisecond?
1 cubic yard per millisecond equals 201,974.026 gallon per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cubic yard per millisecond to gallon per seconds?
Multiply the cubic yard per millisecond value by 201974.026. The converter above does this instantly to whatever precision you set.
How do I convert gallon per seconds back to cubic yard per millisecond?
Use the reverse factor: 1 gallon per seconds equals 0.0000049511 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 gallon per seconds?
Gallon per Seconds (gal/s) is a unit of flow rate.
Is the cubic yard per millisecond to gallon per seconds conversion exact?
Yes. Both cubic yard per millisecond and gallon per seconds are defined by fixed standards rather than physical artifacts, so the factor of 201974.026 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.
