About Converting Gallon per Minutes to Cubic yards per Millisecond
Gallon per Minutes 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. Gallon per Minutes is most often used for us residential and commercial plumbing fixture flow ratings.
Formula
cubic yards per millisecond = gallon per minutes × 8.251886e-8
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per minutes equals 0.0000630901964 base units, and 1 cubic yard per millisecond equals 764.554857984 base units, so dividing one by the other gives the direct gallon per minutes-to-cubic yard per millisecond factor of 8.251886e-8.
Simple example
1 gal/min × 8.251886e-8 = 8.251886e-8 yd3/ms
1 gallon per minutes = 8.251886e-8 cubic yards per millisecond.
Real-world example
60 gal/min × 8.251886e-8 = 0.0000049511 yd3/ms
60 gallon per minutes = 0.0000049511 cubic yards per millisecond.

What is a gallon per minutes?
Gallon per Minutes (gal/min) measures volumetric flow rate. The standard US unit for pump, plumbing, and irrigation flow-rate specifications. It is classified as a US customary flow-rate unit.
What is a cubic yard per millisecond?
Cubic yard per Millisecond (yd3/ms) is a unit of flow rate.
Is the gallon per minutes to cubic yard per millisecond conversion exact?
Yes. Both gallon per minutes and cubic yard per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 8.251886e-8 used above is exact to as many digits as you choose to display.
Where is the gallon per minutes still used today?
United States (plumbing, pump, and irrigation industry standard)
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.
