About Converting Imperial gallon per Seconds to Cubic feet per Millisecond
Imperial gallon per Seconds and Cubic foot per Millisecond 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 feet per millisecond = imperial gallon per seconds × 0.000160543653236
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial gallon per seconds equals 0.00454609 base units, and 1 cubic foot per millisecond equals 28.316846592 base units, so dividing one by the other gives the direct imperial gallon per seconds-to-cubic foot per millisecond factor of 0.000160543653236.
Simple example
1 imp gal/s × 0.0001605436532 = 0.0001605437 ft3/ms
1 imperial gallon per seconds = 0.0001605437 cubic feet per millisecond.
Real-world example
60 imp gal/s × 0.0001605436532 = 0.0096326192 ft3/ms
60 imperial gallon per seconds = 0.0096326192 cubic feet per millisecond.

Frequently asked questions
How many cubic feet per millisecond are in 1 imperial gallon per seconds?
1 imperial gallon per seconds equals 0.0001605437 cubic feet per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert imperial gallon per seconds to cubic foot per millisecond?
Multiply the imperial gallon per seconds value by 0.0001605436532. The converter above does this instantly to whatever precision you set.
How do I convert cubic foot per millisecond back to imperial gallon per seconds?
Use the reverse factor: 1 cubic foot per millisecond equals 6,228.835459 imperial gallon per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial gallon per seconds?
Imperial gallon per Seconds (imp gal/s) is a unit of flow rate.
What is a cubic foot per millisecond?
Cubic foot per Millisecond (ft3/ms) is a unit of flow rate.
Is the imperial gallon per seconds to cubic foot per millisecond conversion exact?
Yes. Both imperial gallon per seconds and cubic foot per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.0001605436532 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.
