About Converting Imperial gallons per Millisecond to Cubic yard per Seconds
Imperial gallon per Millisecond and Cubic yard 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
cubic yard per seconds = imperial gallons per millisecond × 5.94606123096
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial gallon per millisecond equals 4.54609 base units, and 1 cubic yard per seconds equals 0.764554857984 base units, so dividing one by the other gives the direct imperial gallon per millisecond-to-cubic yard per seconds factor of 5.94606123096.
Simple example
1 imp gal/ms × 5.946061231 = 5.946061231 yd3/s
1 imperial gallon per millisecond = 5.946061231 cubic yard per seconds.
Real-world example
60 imp gal/ms × 5.946061231 = 356.7636739 yd3/s
60 imperial gallons per millisecond = 356.7636739 cubic yard per seconds.

How do I convert cubic yard per seconds back to imperial gallon per millisecond?
Use the reverse factor: 1 cubic yard per seconds equals 0.1681785574 imperial gallons per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial gallon per millisecond?
Imperial gallon per Millisecond (imp gal/ms) is a unit of flow rate.
What is a cubic yard per seconds?
Cubic yard per Seconds (yd3/s) is a unit of flow rate.
Is the imperial gallon per millisecond to cubic yard per seconds conversion exact?
Yes. Both imperial gallon per millisecond and cubic yard per seconds are defined by fixed standards rather than physical artifacts, so the factor of 5.946061231 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.
