About Converting Imperial gallons per Millisecond to Cubic inches per Millisecond
Imperial gallon per Millisecond and Cubic inch 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 inches per millisecond = imperial gallons per millisecond × 277.419432792
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 inch per millisecond equals 0.016387064 base units, so dividing one by the other gives the direct imperial gallon per millisecond-to-cubic inch per millisecond factor of 277.419432792.
Simple example
1 imp gal/ms × 277.4194328 = 277.4194328 in3/ms
1 imperial gallon per millisecond = 277.4194328 cubic inches per millisecond.
Real-world example
60 imp gal/ms × 277.4194328 = 16,645.16597 in3/ms
60 imperial gallons per millisecond = 16,645.16597 cubic inches per millisecond.

Frequently asked questions
How many cubic inches per millisecond are in 1 imperial gallon per millisecond?
1 imperial gallon per millisecond equals 277.4194328 cubic inches per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert imperial gallon per millisecond to cubic inch per millisecond?
Multiply the imperial gallon per millisecond value by 277.4194328. The converter above does this instantly to whatever precision you set.
How do I convert cubic inch per millisecond back to imperial gallon per millisecond?
Use the reverse factor: 1 cubic inch per millisecond equals 0.0036046502 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 inch per millisecond?
Cubic inch per Millisecond (in3/ms) is a unit of flow rate.
Is the imperial gallon per millisecond to cubic inch per millisecond conversion exact?
Yes. Both imperial gallon per millisecond and cubic inch per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 277.4194328 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.
