About Converting Imperial quarts per Millisecond to Gallon per Hours
Imperial quart per Millisecond and Gallon 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
gallon per hours = imperial quarts per millisecond × 1080854.93295
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial quart per millisecond equals 1.1365225 base units, and 1 gallon per hours equals 0.00000105150327333 base units, so dividing one by the other gives the direct imperial quart per millisecond-to-gallon per hours factor of 1080854.93295.
Simple example
1 imp qt/ms × 1080854.933 = 1,080,854.933 gal/h
1 imperial quart per millisecond = 1,080,854.933 gallon per hours.
Real-world example
60 imp qt/ms × 1080854.933 = 64,851,295.98 gal/h
60 imperial quarts per millisecond = 64,851,295.98 gallon per hours.

Frequently asked questions
How many gallon per hours are in 1 imperial quart per millisecond?
1 imperial quart per millisecond equals 1,080,854.933 gallon per hours, using the exact defined conversion factor rather than an estimate.
How do I convert imperial quart per millisecond to gallon per hours?
Multiply the imperial quart per millisecond value by 1080854.933. The converter above does this instantly to whatever precision you set.
How do I convert gallon per hours back to imperial quart per millisecond?
Use the reverse factor: 1 gallon per hours equals 9.251935e-7 imperial quarts per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial quart per millisecond?
Imperial quart per Millisecond (imp qt/ms) is a unit of flow rate.
What is a gallon per hours?
Gallon per Hours (gal/h) is a unit of flow rate.
Is the imperial quart per millisecond to gallon per hours conversion exact?
Yes. Both imperial quart per millisecond and gallon per hours are defined by fixed standards rather than physical artifacts, so the factor of 1080854.933 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.
