About Converting Imperial quarts per Millisecond to Gallons per Millisecond
Imperial quart per Millisecond and Gallon per Millisecond 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
gallons per millisecond = imperial quarts per millisecond × 0.300237481376
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 millisecond equals 3.785411784 base units, so dividing one by the other gives the direct imperial quart per millisecond-to-gallon per millisecond factor of 0.300237481376.
Simple example
1 imp qt/ms × 0.3002374814 = 0.3002374814 gal/ms
1 imperial quart per millisecond = 0.3002374814 gallons per millisecond.
Real-world example
60 imp qt/ms × 0.3002374814 = 18.01424888 gal/ms
60 imperial quarts per millisecond = 18.01424888 gallons per millisecond.

Frequently asked questions
How many gallons per millisecond are in 1 imperial quart per millisecond?
1 imperial quart per millisecond equals 0.3002374814 gallons per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert imperial quart per millisecond to gallon per millisecond?
Multiply the imperial quart per millisecond value by 0.3002374814. The converter above does this instantly to whatever precision you set.
How do I convert gallon per millisecond back to imperial quart per millisecond?
Use the reverse factor: 1 gallon per millisecond equals 3.330696739 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 millisecond?
Gallon per Millisecond (gal/ms) is a unit of flow rate.
Is the imperial quart per millisecond to gallon per millisecond conversion exact?
Yes. Both imperial quart per millisecond and gallon per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.3002374814 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.
