About Converting Imperial gallons per Millisecond to Cubic foot per Seconds
Imperial gallon per Millisecond and Cubic foot per Seconds 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 seconds = imperial gallons per millisecond × 160.543653236
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 seconds equals 0.028316846592 base units, so dividing one by the other gives the direct imperial gallon per millisecond-to-cubic foot per seconds factor of 160.543653236.
Simple example
1 imp gal/ms × 160.5436532 = 160.5436532 ft3/s
1 imperial gallon per millisecond = 160.5436532 cubic foot per seconds.
Real-world example
60 imp gal/ms × 160.5436532 = 9,632.619194 ft3/s
60 imperial gallons per millisecond = 9,632.619194 cubic foot per seconds.

Frequently asked questions
How many cubic foot per seconds are in 1 imperial gallon per millisecond?
1 imperial gallon per millisecond equals 160.5436532 cubic foot per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert imperial gallon per millisecond to cubic foot per seconds?
Multiply the imperial gallon per millisecond value by 160.5436532. The converter above does this instantly to whatever precision you set.
How do I convert cubic foot per seconds back to imperial gallon per millisecond?
Use the reverse factor: 1 cubic foot per seconds equals 0.0062288355 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 seconds?
Cubic foot per Seconds (ft3/s) measures volumetric flow rate. One cubic foot of volume passing a point every second. It is classified as a US customary flow-rate unit.
Is the imperial gallon per millisecond to cubic foot per seconds conversion exact?
Yes. Both imperial gallon per millisecond and cubic foot per seconds are defined by fixed standards rather than physical artifacts, so the factor of 160.5436532 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.
