About Converting Imperial gallons per Millisecond to Quart per Minutes
Imperial gallon per Millisecond and Quart per Minutes 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
quart per minutes = imperial gallons per millisecond × 288227.982121
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 quart per minutes equals 0.0000157725491 base units, so dividing one by the other gives the direct imperial gallon per millisecond-to-quart per minutes factor of 288227.982121.
Simple example
1 imp gal/ms × 288227.9821 = 288,227.9821 qt/min
1 imperial gallon per millisecond = 288,227.9821 quart per minutes.
Real-world example
60 imp gal/ms × 288227.9821 = 17,293,678.93 qt/min
60 imperial gallons per millisecond = 17,293,678.93 quart per minutes.

Frequently asked questions
How many quart per minutes are in 1 imperial gallon per millisecond?
1 imperial gallon per millisecond equals 288,227.9821 quart per minutes, using the exact defined conversion factor rather than an estimate.
How do I convert imperial gallon per millisecond to quart per minutes?
Multiply the imperial gallon per millisecond value by 288227.9821. The converter above does this instantly to whatever precision you set.
How do I convert quart per minutes back to imperial gallon per millisecond?
Use the reverse factor: 1 quart per minutes equals 0.0000034695 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 quart per minutes?
Quart per Minutes (qt/min) is a unit of flow rate.
Is the imperial gallon per millisecond to quart per minutes conversion exact?
Yes. Both imperial gallon per millisecond and quart per minutes are defined by fixed standards rather than physical artifacts, so the factor of 288227.9821 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.
