About Converting Imperial gallons per Millisecond to Quart per Hours
Imperial gallon per Millisecond and Quart per Hours 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 hours = imperial gallons per millisecond × 17293678.9273
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 hours equals 2.628758e-7 base units, so dividing one by the other gives the direct imperial gallon per millisecond-to-quart per hours factor of 17293678.9273.
Simple example
1 imp gal/ms × 17293678.93 = 17,293,678.93 qt/h
1 imperial gallon per millisecond = 17,293,678.93 quart per hours.
Real-world example
60 imp gal/ms × 17293678.93 = 1,037,620,736 qt/h
60 imperial gallons per millisecond = 1,037,620,736 quart per hours.

Frequently asked questions
How many quart per hours are in 1 imperial gallon per millisecond?
1 imperial gallon per millisecond equals 17,293,678.93 quart per hours, using the exact defined conversion factor rather than an estimate.
How do I convert imperial gallon per millisecond to quart per hours?
Multiply the imperial gallon per millisecond value by 17293678.93. The converter above does this instantly to whatever precision you set.
How do I convert quart per hours back to imperial gallon per millisecond?
Use the reverse factor: 1 quart per hours equals 5.78246e-8 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 hours?
Quart per Hours (qt/h) is a unit of flow rate.
Is the imperial gallon per millisecond to quart per hours conversion exact?
Yes. Both imperial gallon per millisecond and quart per hours are defined by fixed standards rather than physical artifacts, so the factor of 17293678.93 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.
