About Converting Cubic feet per Millisecond to Imperial gallon per Minutes
Cubic foot per Millisecond and Imperial gallon 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
imperial gallon per minutes = cubic feet per millisecond × 373730.127543
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic foot per millisecond equals 28.316846592 base units, and 1 imperial gallon per minutes equals 0.0000757681666667 base units, so dividing one by the other gives the direct cubic foot per millisecond-to-imperial gallon per minutes factor of 373730.127543.
Simple example
1 ft3/ms × 373730.1275 = 373,730.1275 imp gal/min
1 cubic foot per millisecond = 373,730.1275 imperial gallon per minutes.
Real-world example
60 ft3/ms × 373730.1275 = 22,423,807.65 imp gal/min
60 cubic feet per millisecond = 22,423,807.65 imperial gallon per minutes.

Frequently asked questions
How many imperial gallon per minutes are in 1 cubic foot per millisecond?
1 cubic foot per millisecond equals 373,730.1275 imperial gallon per minutes, using the exact defined conversion factor rather than an estimate.
How do I convert cubic foot per millisecond to imperial gallon per minutes?
Multiply the cubic foot per millisecond value by 373730.1275. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per minutes back to cubic foot per millisecond?
Use the reverse factor: 1 imperial gallon per minutes equals 0.0000026757 cubic feet per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic foot per millisecond?
Cubic foot per Millisecond (ft3/ms) is a unit of flow rate.
What is a imperial gallon per minutes?
Imperial gallon per Minutes (imp gal/min) is a unit of flow rate.
Is the cubic foot per millisecond to imperial gallon per minutes conversion exact?
Yes. Both cubic foot per millisecond and imperial gallon per minutes are defined by fixed standards rather than physical artifacts, so the factor of 373730.1275 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.
