About Converting Imperial gallon per Minutes to Quarts per Millisecond
Imperial gallon per Minutes and Quart 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
quarts per millisecond = imperial gallon per minutes × 0.000080063328367
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial gallon per minutes equals 0.0000757681666667 base units, and 1 quart per millisecond equals 0.946352946 base units, so dividing one by the other gives the direct imperial gallon per minutes-to-quart per millisecond factor of 0.000080063328367.
Simple example
1 imp gal/min × 0.00008006332837 = 0.0000800633 qt/ms
1 imperial gallon per minutes = 0.0000800633 quarts per millisecond.
Real-world example
60 imp gal/min × 0.00008006332837 = 0.0048037997 qt/ms
60 imperial gallon per minutes = 0.0048037997 quarts per millisecond.

Frequently asked questions
How many quarts per millisecond are in 1 imperial gallon per minutes?
1 imperial gallon per minutes equals 0.0000800633 quarts per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert imperial gallon per minutes to quart per millisecond?
Multiply the imperial gallon per minutes value by 0.00008006332837. The converter above does this instantly to whatever precision you set.
How do I convert quart per millisecond back to imperial gallon per minutes?
Use the reverse factor: 1 quart per millisecond equals 12,490.11277 imperial gallon per minutes. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial gallon per minutes?
Imperial gallon per Minutes (imp gal/min) is a unit of flow rate.
What is a quart per millisecond?
Quart per Millisecond (qt/ms) is a unit of flow rate.
Is the imperial gallon per minutes to quart per millisecond conversion exact?
Yes. Both imperial gallon per minutes and quart per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.00008006332837 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.
