About Converting Imperial gallons per Millisecond to Cubic inch per Minutes
Imperial gallon per Millisecond and Cubic inch per Minutes 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 inch per minutes = imperial gallons per millisecond × 16645165.9675
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 inch per minutes equals 2.731177e-7 base units, so dividing one by the other gives the direct imperial gallon per millisecond-to-cubic inch per minutes factor of 16645165.9675.
Simple example
1 imp gal/ms × 16645165.97 = 16,645,165.97 in3/min
1 imperial gallon per millisecond = 16,645,165.97 cubic inch per minutes.
Real-world example
60 imp gal/ms × 16645165.97 = 998,709,958 in3/min
60 imperial gallons per millisecond = 998,709,958 cubic inch per minutes.

Frequently asked questions
How many cubic inch per minutes are in 1 imperial gallon per millisecond?
1 imperial gallon per millisecond equals 16,645,165.97 cubic inch per minutes, using the exact defined conversion factor rather than an estimate.
How do I convert imperial gallon per millisecond to cubic inch per minutes?
Multiply the imperial gallon per millisecond value by 16645165.97. The converter above does this instantly to whatever precision you set.
How do I convert cubic inch per minutes back to imperial gallon per millisecond?
Use the reverse factor: 1 cubic inch per minutes equals 6.00775e-8 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 inch per minutes?
Cubic inch per Minutes (in3/min) is a unit of flow rate.
Is the imperial gallon per millisecond to cubic inch per minutes conversion exact?
Yes. Both imperial gallon per millisecond and cubic inch per minutes are defined by fixed standards rather than physical artifacts, so the factor of 16645165.97 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.
