About Converting Imperial gallons per Millisecond to Imperial quart per Seconds
Imperial gallon per Millisecond and Imperial quart per Seconds 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 quart per seconds = imperial gallons per millisecond × 4000
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 imperial quart per seconds equals 0.0011365225 base units, so dividing one by the other gives the direct imperial gallon per millisecond-to-imperial quart per seconds factor of 4000.
Simple example
1 imp gal/ms × 4000 = 4,000 imp qt/s
1 imperial gallon per millisecond = 4,000 imperial quart per seconds.
Real-world example
60 imp gal/ms × 4000 = 240,000 imp qt/s
60 imperial gallons per millisecond = 240,000 imperial quart per seconds.

Frequently asked questions
How many imperial quart per seconds are in 1 imperial gallon per millisecond?
1 imperial gallon per millisecond equals 4,000 imperial quart per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert imperial gallon per millisecond to imperial quart per seconds?
Multiply the imperial gallon per millisecond value by 4000. The converter above does this instantly to whatever precision you set.
How do I convert imperial quart per seconds back to imperial gallon per millisecond?
Use the reverse factor: 1 imperial quart per seconds equals 0.00025 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 imperial quart per seconds?
Imperial quart per Seconds (imp qt/s) is a unit of flow rate.
Is the imperial gallon per millisecond to imperial quart per seconds conversion exact?
Yes. Both imperial gallon per millisecond and imperial quart per seconds are defined by fixed standards rather than physical artifacts, so the factor of 4000 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.
