About Converting Imperial gallons per Millisecond to Quart per Seconds
Imperial gallon per Millisecond and 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
quart per seconds = imperial gallons per millisecond × 4803.79970202
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 seconds equals 0.000946352946 base units, so dividing one by the other gives the direct imperial gallon per millisecond-to-quart per seconds factor of 4803.79970202.
Simple example
1 imp gal/ms × 4803.799702 = 4,803.799702 qt/s
1 imperial gallon per millisecond = 4,803.799702 quart per seconds.
Real-world example
60 imp gal/ms × 4803.799702 = 288,227.9821 qt/s
60 imperial gallons per millisecond = 288,227.9821 quart per seconds.

Frequently asked questions
How many quart per seconds are in 1 imperial gallon per millisecond?
1 imperial gallon per millisecond equals 4,803.799702 quart per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert imperial gallon per millisecond to quart per seconds?
Multiply the imperial gallon per millisecond value by 4803.799702. The converter above does this instantly to whatever precision you set.
How do I convert quart per seconds back to imperial gallon per millisecond?
Use the reverse factor: 1 quart per seconds equals 0.0002081685 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 seconds?
Quart per Seconds (qt/s) is a unit of flow rate.
Is the imperial gallon per millisecond to quart per seconds conversion exact?
Yes. Both imperial gallon per millisecond and quart per seconds are defined by fixed standards rather than physical artifacts, so the factor of 4803.799702 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.
