About Converting Cubic yard per Years to Imperial gallons per Millisecond
Cubic yard per Years 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 years × 5.329366e-9
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic yard per years equals 2.422778e-8 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 years-to-imperial gallon per millisecond factor of 5.329366e-9.
Simple example
1 yd3/yr × 5.329366e-9 = 5.329366e-9 imp gal/ms
1 cubic yard per years = 5.329366e-9 imperial gallons per millisecond.
Real-world example
60 yd3/yr × 5.329366e-9 = 3.19762e-7 imp gal/ms
60 cubic yard per years = 3.19762e-7 imperial gallons per millisecond.

Frequently asked questions
How many imperial gallons per millisecond are in 1 cubic yard per years?
1 cubic yard per years equals 5.329366e-9 imperial gallons per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert cubic yard per years to imperial gallon per millisecond?
Multiply the cubic yard per years value by 5.329366e-9. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per millisecond back to cubic yard per years?
Use the reverse factor: 1 imperial gallon per millisecond equals 187,639,568.9 cubic yard per years. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic yard per years?
Cubic yard per Years (yd3/yr) 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 years to imperial gallon per millisecond conversion exact?
Yes. Both cubic yard per years and imperial gallon per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 5.329366e-9 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.
