About Converting Cubic yards per Millisecond to Imperial gallon per Seconds
Cubic yard per Millisecond and Imperial gallon 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
imperial gallon per seconds = cubic yards per millisecond × 168178.557394
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 imperial gallon per seconds equals 0.00454609 base units, so dividing one by the other gives the direct cubic yard per millisecond-to-imperial gallon per seconds factor of 168178.557394.
Simple example
1 yd3/ms × 168178.5574 = 168,178.5574 imp gal/s
1 cubic yard per millisecond = 168,178.5574 imperial gallon per seconds.
Real-world example
60 yd3/ms × 168178.5574 = 10,090,713.44 imp gal/s
60 cubic yards per millisecond = 10,090,713.44 imperial gallon per seconds.

Frequently asked questions
How many imperial gallon per seconds are in 1 cubic yard per millisecond?
1 cubic yard per millisecond equals 168,178.5574 imperial gallon per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cubic yard per millisecond to imperial gallon per seconds?
Multiply the cubic yard per millisecond value by 168178.5574. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per seconds back to cubic yard per millisecond?
Use the reverse factor: 1 imperial gallon per seconds equals 0.0000059461 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 imperial gallon per seconds?
Imperial gallon per Seconds (imp gal/s) is a unit of flow rate.
Is the cubic yard per millisecond to imperial gallon per seconds conversion exact?
Yes. Both cubic yard per millisecond and imperial gallon per seconds are defined by fixed standards rather than physical artifacts, so the factor of 168178.5574 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.
