About Converting Imperial gallon per Minutes to Gallons per Millisecond
Imperial gallon per Minutes and 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
gallons per millisecond = imperial gallon per minutes × 0.0000200158320917
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial gallon per minutes equals 0.0000757681666667 base units, and 1 gallon per millisecond equals 3.785411784 base units, so dividing one by the other gives the direct imperial gallon per minutes-to-gallon per millisecond factor of 0.0000200158320917.
Simple example
1 imp gal/min × 0.00002001583209 = 0.0000200158 gal/ms
1 imperial gallon per minutes = 0.0000200158 gallons per millisecond.
Real-world example
60 imp gal/min × 0.00002001583209 = 0.0012009499 gal/ms
60 imperial gallon per minutes = 0.0012009499 gallons per millisecond.

Frequently asked questions
How many gallons per millisecond are in 1 imperial gallon per minutes?
1 imperial gallon per minutes equals 0.0000200158 gallons per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert imperial gallon per minutes to gallon per millisecond?
Multiply the imperial gallon per minutes value by 0.00002001583209. The converter above does this instantly to whatever precision you set.
How do I convert gallon per millisecond back to imperial gallon per minutes?
Use the reverse factor: 1 gallon per millisecond equals 49,960.45108 imperial gallon per minutes. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial gallon per minutes?
Imperial gallon per Minutes (imp gal/min) is a unit of flow rate.
What is a gallon per millisecond?
Gallon per Millisecond (gal/ms) is a unit of flow rate.
Is the imperial gallon per minutes to gallon per millisecond conversion exact?
Yes. Both imperial gallon per minutes and gallon per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.00002001583209 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.
