About Converting Quarts per Millisecond to Imperial gallon per Minutes
Quart per Millisecond and Imperial gallon 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
imperial gallon per minutes = quarts per millisecond × 12490.1127694
This factor comes from each unit's defined relationship to the category's base unit: 1 quart per millisecond equals 0.946352946 base units, and 1 imperial gallon per minutes equals 0.0000757681666667 base units, so dividing one by the other gives the direct quart per millisecond-to-imperial gallon per minutes factor of 12490.1127694.
Simple example
1 qt/ms × 12490.11277 = 12,490.11277 imp gal/min
1 quart per millisecond = 12,490.11277 imperial gallon per minutes.
Real-world example
60 qt/ms × 12490.11277 = 749,406.7662 imp gal/min
60 quarts per millisecond = 749,406.7662 imperial gallon per minutes.

Frequently asked questions
How many imperial gallon per minutes are in 1 quart per millisecond?
1 quart per millisecond equals 12,490.11277 imperial gallon per minutes, using the exact defined conversion factor rather than an estimate.
How do I convert quart per millisecond to imperial gallon per minutes?
Multiply the quart per millisecond value by 12490.11277. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per minutes back to quart per millisecond?
Use the reverse factor: 1 imperial gallon per minutes equals 0.0000800633 quarts per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a quart per millisecond?
Quart per Millisecond (qt/ms) is a unit of flow rate.
What is a imperial gallon per minutes?
Imperial gallon per Minutes (imp gal/min) is a unit of flow rate.
Is the quart per millisecond to imperial gallon per minutes conversion exact?
Yes. Both quart per millisecond and imperial gallon per minutes are defined by fixed standards rather than physical artifacts, so the factor of 12490.11277 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.
