About Converting Gallon per Seconds to Cubic yards per Millisecond
Gallon per Seconds and Cubic yard 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
cubic yards per millisecond = gallon per seconds × 0.00000495113168724
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per seconds equals 0.003785411784 base units, and 1 cubic yard per millisecond equals 764.554857984 base units, so dividing one by the other gives the direct gallon per seconds-to-cubic yard per millisecond factor of 0.00000495113168724.
Simple example
1 gal/s × 0.000004951131687 = 0.0000049511 yd3/ms
1 gallon per seconds = 0.0000049511 cubic yards per millisecond.
Real-world example
60 gal/s × 0.000004951131687 = 0.0002970679 yd3/ms
60 gallon per seconds = 0.0002970679 cubic yards per millisecond.

Frequently asked questions
How many cubic yards per millisecond are in 1 gallon per seconds?
1 gallon per seconds equals 0.0000049511 cubic yards per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per seconds to cubic yard per millisecond?
Multiply the gallon per seconds value by 0.000004951131687. The converter above does this instantly to whatever precision you set.
How do I convert cubic yard per millisecond back to gallon per seconds?
Use the reverse factor: 1 cubic yard per millisecond equals 201,974.026 gallon per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per seconds?
Gallon per Seconds (gal/s) is a unit of flow rate.
What is a cubic yard per millisecond?
Cubic yard per Millisecond (yd3/ms) is a unit of flow rate.
Is the gallon per seconds to cubic yard per millisecond conversion exact?
Yes. Both gallon per seconds and cubic yard per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.000004951131687 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.
