About Converting Cubic feet per Millisecond to Imperial gallon per Hours
Cubic foot per Millisecond and Imperial gallon per Hours 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 hours = cubic feet per millisecond × 22423807.6526
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 hours equals 0.00000126280277778 base units, so dividing one by the other gives the direct cubic foot per millisecond-to-imperial gallon per hours factor of 22423807.6526.
Simple example
1 ft3/ms × 22423807.65 = 22,423,807.65 imp gal/h
1 cubic foot per millisecond = 22,423,807.65 imperial gallon per hours.
Real-world example
60 ft3/ms × 22423807.65 = 1,345,428,459 imp gal/h
60 cubic feet per millisecond = 1,345,428,459 imperial gallon per hours.

Frequently asked questions
How many imperial gallon per hours are in 1 cubic foot per millisecond?
1 cubic foot per millisecond equals 22,423,807.65 imperial gallon per hours, using the exact defined conversion factor rather than an estimate.
How do I convert cubic foot per millisecond to imperial gallon per hours?
Multiply the cubic foot per millisecond value by 22423807.65. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per hours back to cubic foot per millisecond?
Use the reverse factor: 1 imperial gallon per hours equals 4.459546e-8 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 hours?
Imperial gallon per Hours (imp gal/h) is a unit of flow rate.
Is the cubic foot per millisecond to imperial gallon per hours conversion exact?
Yes. Both cubic foot per millisecond and imperial gallon per hours are defined by fixed standards rather than physical artifacts, so the factor of 22423807.65 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.
