About Converting Imperial gallons per Millisecond to Cubic yard per Days
Imperial gallon per Millisecond and Cubic yard per Days 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 days = imperial gallons per millisecond × 513739.690355
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 days equals 0.00000884901456 base units, so dividing one by the other gives the direct imperial gallon per millisecond-to-cubic yard per days factor of 513739.690355.
Simple example
1 imp gal/ms × 513739.6904 = 513,739.6904 yd3/d
1 imperial gallon per millisecond = 513,739.6904 cubic yard per days.
Real-world example
60 imp gal/ms × 513739.6904 = 30,824,381.42 yd3/d
60 imperial gallons per millisecond = 30,824,381.42 cubic yard per days.

Frequently asked questions
How many cubic yard per days are in 1 imperial gallon per millisecond?
1 imperial gallon per millisecond equals 513,739.6904 cubic yard per days, using the exact defined conversion factor rather than an estimate.
How do I convert imperial gallon per millisecond to cubic yard per days?
Multiply the imperial gallon per millisecond value by 513739.6904. The converter above does this instantly to whatever precision you set.
How do I convert cubic yard per days back to imperial gallon per millisecond?
Use the reverse factor: 1 cubic yard per days equals 0.0000019465 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 days?
Cubic yard per Days (yd3/d) is a unit of flow rate.
Is the imperial gallon per millisecond to cubic yard per days conversion exact?
Yes. Both imperial gallon per millisecond and cubic yard per days are defined by fixed standards rather than physical artifacts, so the factor of 513739.6904 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.
