About Converting Cubic yard per Days to Imperial gallons per Millisecond
Cubic yard per Days and Imperial gallon 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
imperial gallons per millisecond = cubic yard per days × 0.00000194651108095
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic yard per days equals 0.00000884901456 base units, and 1 imperial gallon per millisecond equals 4.54609 base units, so dividing one by the other gives the direct cubic yard per days-to-imperial gallon per millisecond factor of 0.00000194651108095.
Simple example
1 yd3/d × 0.000001946511081 = 0.0000019465 imp gal/ms
1 cubic yard per days = 0.0000019465 imperial gallons per millisecond.
Real-world example
60 yd3/d × 0.000001946511081 = 0.0001167907 imp gal/ms
60 cubic yard per days = 0.0001167907 imperial gallons per millisecond.

Frequently asked questions
How many imperial gallons per millisecond are in 1 cubic yard per days?
1 cubic yard per days equals 0.0000019465 imperial gallons per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert cubic yard per days to imperial gallon per millisecond?
Multiply the cubic yard per days value by 0.000001946511081. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per millisecond back to cubic yard per days?
Use the reverse factor: 1 imperial gallon per millisecond equals 513,739.6904 cubic yard per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic yard per days?
Cubic yard per Days (yd3/d) is a unit of flow rate.
What is a imperial gallon per millisecond?
Imperial gallon per Millisecond (imp gal/ms) is a unit of flow rate.
Is the cubic yard per days to imperial gallon per millisecond conversion exact?
Yes. Both cubic yard per days and imperial gallon per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.000001946511081 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.
