About Converting Imperial fluid ounce per Seconds to Imperial quarts per Millisecond
Imperial fluid ounce 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 = imperial fluid ounce per seconds × 0.000025
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial fluid ounce per seconds equals 0.0000284130625 base units, and 1 imperial quart per millisecond equals 1.1365225 base units, so dividing one by the other gives the direct imperial fluid ounce per seconds-to-imperial quart per millisecond factor of 0.000025.
Simple example
1 imp fl oz/s × 0.000025 = 0.000025 imp qt/ms
1 imperial fluid ounce per seconds = 0.000025 imperial quarts per millisecond.
Real-world example
60 imp fl oz/s × 0.000025 = 0.0015 imp qt/ms
60 imperial fluid ounce per seconds = 0.0015 imperial quarts per millisecond.

Frequently asked questions
How many imperial quarts per millisecond are in 1 imperial fluid ounce per seconds?
1 imperial fluid ounce per seconds equals 0.000025 imperial quarts per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert imperial fluid ounce per seconds to imperial quart per millisecond?
Multiply the imperial fluid ounce per seconds value by 0.000025. The converter above does this instantly to whatever precision you set.
How do I convert imperial quart per millisecond back to imperial fluid ounce per seconds?
Use the reverse factor: 1 imperial quart per millisecond equals 40,000 imperial fluid ounce per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial fluid ounce per seconds?
Imperial fluid ounce per Seconds (imp fl oz/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 imperial fluid ounce per seconds to imperial quart per millisecond conversion exact?
Yes. Both imperial fluid ounce per seconds and imperial quart per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.000025 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.
