About Converting Cubic yards per Millisecond to Gallons per Millisecond
Cubic yard per Millisecond and Gallon 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. Both are volumetric flow rate units.
Formula
gallons per millisecond = cubic yards per millisecond × 201.974025974
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 millisecond equals 3.785411784 base units, so dividing one by the other gives the direct cubic yard per millisecond-to-gallon per millisecond factor of 201.974025974.
Simple example
1 yd3/ms × 201.974026 = 201.974026 gal/ms
1 cubic yard per millisecond = 201.974026 gallons per millisecond.
Real-world example
60 yd3/ms × 201.974026 = 12,118.44156 gal/ms
60 cubic yards per millisecond = 12,118.44156 gallons per millisecond.

Frequently asked questions
How many gallons per millisecond are in 1 cubic yard per millisecond?
1 cubic yard per millisecond equals 201.974026 gallons per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert cubic yard per millisecond to gallon per millisecond?
Multiply the cubic yard per millisecond value by 201.974026. The converter above does this instantly to whatever precision you set.
How do I convert gallon per millisecond back to cubic yard per millisecond?
Use the reverse factor: 1 gallon per millisecond equals 0.0049511317 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 millisecond?
Gallon per Millisecond (gal/ms) is a unit of flow rate.
Is the cubic yard per millisecond to gallon per millisecond conversion exact?
Yes. Both cubic yard per millisecond and gallon per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 201.974026 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.
