About Converting Imperial quart per Minutes to Imperial gallons per Millisecond
Imperial quart per Minutes and Imperial gallon 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
imperial gallons per millisecond = imperial quart per minutes × 0.00000416666666667
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial quart per minutes equals 0.0000189420416667 base units, and 1 imperial gallon per millisecond equals 4.54609 base units, so dividing one by the other gives the direct imperial quart per minutes-to-imperial gallon per millisecond factor of 0.00000416666666667.
Simple example
1 imp qt/min × 0.000004166666667 = 0.0000041667 imp gal/ms
1 imperial quart per minutes = 0.0000041667 imperial gallons per millisecond.
Real-world example
60 imp qt/min × 0.000004166666667 = 0.00025 imp gal/ms
60 imperial quart per minutes = 0.00025 imperial gallons per millisecond.

Frequently asked questions
How many imperial gallons per millisecond are in 1 imperial quart per minutes?
1 imperial quart per minutes equals 0.0000041667 imperial gallons per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert imperial quart per minutes to imperial gallon per millisecond?
Multiply the imperial quart per minutes value by 0.000004166666667. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per millisecond back to imperial quart per minutes?
Use the reverse factor: 1 imperial gallon per millisecond equals 240,000 imperial quart per minutes. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial quart per minutes?
Imperial quart per Minutes (imp qt/min) is a unit of flow rate.
What is a imperial gallon per millisecond?
Imperial gallon per Millisecond (imp gal/ms) is a unit of flow rate.
Is the imperial quart per minutes to imperial gallon per millisecond conversion exact?
Yes. Both imperial quart per minutes and imperial gallon per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.000004166666667 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.
