About Converting Gallons per Millisecond to Imperial quart per Seconds
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 = gallons per millisecond × 3330.69673852
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per millisecond equals 3.785411784 base units, and 1 imperial quart per seconds equals 0.0011365225 base units, so dividing one by the other gives the direct gallon per millisecond-to-imperial quart per seconds factor of 3330.69673852.
Simple example
1 gal/ms × 3330.696739 = 3,330.696739 imp qt/s
1 gallon per millisecond = 3,330.696739 imperial quart per seconds.
Real-world example
60 gal/ms × 3330.696739 = 199,841.8043 imp qt/s
60 gallons per millisecond = 199,841.8043 imperial quart per seconds.

Frequently asked questions
How many imperial quart per seconds are in 1 gallon per millisecond?
1 gallon per millisecond equals 3,330.696739 imperial quart per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per millisecond to imperial quart per seconds?
Multiply the gallon per millisecond value by 3330.696739. The converter above does this instantly to whatever precision you set.
How do I convert imperial quart per seconds back to gallon per millisecond?
Use the reverse factor: 1 imperial quart per seconds equals 0.0003002375 gallons per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per millisecond?
Gallon per Millisecond (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 gallon per millisecond to imperial quart per seconds conversion exact?
Yes. Both gallon per millisecond and imperial quart per seconds are defined by fixed standards rather than physical artifacts, so the factor of 3330.696739 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.
