About Converting Imperial gallon per Seconds to Cubic yards per Millisecond
Imperial 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 = imperial gallon per seconds × 0.00000594606123096
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial gallon per seconds equals 0.00454609 base units, and 1 cubic yard per millisecond equals 764.554857984 base units, so dividing one by the other gives the direct imperial gallon per seconds-to-cubic yard per millisecond factor of 0.00000594606123096.
Simple example
1 imp gal/s × 0.000005946061231 = 0.0000059461 yd3/ms
1 imperial gallon per seconds = 0.0000059461 cubic yards per millisecond.
Real-world example
60 imp gal/s × 0.000005946061231 = 0.0003567637 yd3/ms
60 imperial gallon per seconds = 0.0003567637 cubic yards per millisecond.

Frequently asked questions
How many cubic yards per millisecond are in 1 imperial gallon per seconds?
1 imperial gallon per seconds equals 0.0000059461 cubic yards per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert imperial gallon per seconds to cubic yard per millisecond?
Multiply the imperial gallon per seconds value by 0.000005946061231. The converter above does this instantly to whatever precision you set.
How do I convert cubic yard per millisecond back to imperial gallon per seconds?
Use the reverse factor: 1 cubic yard per millisecond equals 168,178.5574 imperial gallon per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial gallon per seconds?
Imperial gallon per Seconds (imp 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 imperial gallon per seconds to cubic yard per millisecond conversion exact?
Yes. Both imperial gallon per seconds and cubic yard per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.000005946061231 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.
