About Converting Imperial gallons per Millisecond to Cubic foot per Hours
Imperial gallon per Millisecond and Cubic foot 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
cubic foot per hours = imperial gallons per millisecond × 577957.151649
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 foot per hours equals 0.00000786579072 base units, so dividing one by the other gives the direct imperial gallon per millisecond-to-cubic foot per hours factor of 577957.151649.
Simple example
1 imp gal/ms × 577957.1516 = 577,957.1516 ft3/h
1 imperial gallon per millisecond = 577,957.1516 cubic foot per hours.
Real-world example
60 imp gal/ms × 577957.1516 = 34,677,429.1 ft3/h
60 imperial gallons per millisecond = 34,677,429.1 cubic foot per hours.

Frequently asked questions
How many cubic foot per hours are in 1 imperial gallon per millisecond?
1 imperial gallon per millisecond equals 577,957.1516 cubic foot per hours, using the exact defined conversion factor rather than an estimate.
How do I convert imperial gallon per millisecond to cubic foot per hours?
Multiply the imperial gallon per millisecond value by 577957.1516. The converter above does this instantly to whatever precision you set.
How do I convert cubic foot per hours back to imperial gallon per millisecond?
Use the reverse factor: 1 cubic foot per hours equals 0.0000017302 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 foot per hours?
Cubic foot per Hours (ft3/h) is a unit of flow rate.
Is the imperial gallon per millisecond to cubic foot per hours conversion exact?
Yes. Both imperial gallon per millisecond and cubic foot per hours are defined by fixed standards rather than physical artifacts, so the factor of 577957.1516 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.
