About Converting Imperial gallons per Millisecond to Cubic foot per Days
Imperial gallon per Millisecond and Cubic foot per Days 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 days = imperial gallons per millisecond × 13870971.6396
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 days equals 3.277413e-7 base units, so dividing one by the other gives the direct imperial gallon per millisecond-to-cubic foot per days factor of 13870971.6396.
Simple example
1 imp gal/ms × 13870971.64 = 13,870,971.64 ft3/d
1 imperial gallon per millisecond = 13,870,971.64 cubic foot per days.
Real-world example
60 imp gal/ms × 13870971.64 = 832,258,298.4 ft3/d
60 imperial gallons per millisecond = 832,258,298.4 cubic foot per days.

Frequently asked questions
How many cubic foot per days are in 1 imperial gallon per millisecond?
1 imperial gallon per millisecond equals 13,870,971.64 cubic foot per days, using the exact defined conversion factor rather than an estimate.
How do I convert imperial gallon per millisecond to cubic foot per days?
Multiply the imperial gallon per millisecond value by 13870971.64. The converter above does this instantly to whatever precision you set.
How do I convert cubic foot per days back to imperial gallon per millisecond?
Use the reverse factor: 1 cubic foot per days equals 7.2093e-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 foot per days?
Cubic foot per Days (ft3/d) is a unit of flow rate.
Is the imperial gallon per millisecond to cubic foot per days conversion exact?
Yes. Both imperial gallon per millisecond and cubic foot per days are defined by fixed standards rather than physical artifacts, so the factor of 13870971.64 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.
