About Converting Gallon per Seconds to Imperial quarts per Millisecond
Gallon per Seconds and Imperial quart 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
imperial quarts per millisecond = gallon per seconds × 0.00333069673852
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per seconds equals 0.003785411784 base units, and 1 imperial quart per millisecond equals 1.1365225 base units, so dividing one by the other gives the direct gallon per seconds-to-imperial quart per millisecond factor of 0.00333069673852.
Simple example
1 gal/s × 0.003330696739 = 0.0033306967 imp qt/ms
1 gallon per seconds = 0.0033306967 imperial quarts per millisecond.
Real-world example
60 gal/s × 0.003330696739 = 0.1998418043 imp qt/ms
60 gallon per seconds = 0.1998418043 imperial quarts per millisecond.

Frequently asked questions
How many imperial quarts per millisecond are in 1 gallon per seconds?
1 gallon per seconds equals 0.0033306967 imperial quarts per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per seconds to imperial quart per millisecond?
Multiply the gallon per seconds value by 0.003330696739. The converter above does this instantly to whatever precision you set.
How do I convert imperial quart per millisecond back to gallon per seconds?
Use the reverse factor: 1 imperial quart per millisecond equals 300.2374814 gallon per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per seconds?
Gallon per Seconds (gal/s) is a unit of flow rate.
What is a imperial quart per millisecond?
Imperial quart per Millisecond (imp qt/ms) is a unit of flow rate.
Is the gallon per seconds to imperial quart per millisecond conversion exact?
Yes. Both gallon per seconds and imperial quart per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.003330696739 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.
