About Converting Fluid ounce per Seconds to Quarts per Millisecond
Fluid ounce per Seconds and 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
quarts per millisecond = fluid ounce per seconds × 0.00003125
This factor comes from each unit's defined relationship to the category's base unit: 1 fluid ounce per seconds equals 0.0000295735295625 base units, and 1 quart per millisecond equals 0.946352946 base units, so dividing one by the other gives the direct fluid ounce per seconds-to-quart per millisecond factor of 0.00003125.
Simple example
1 fl oz/s × 0.00003125 = 0.00003125 qt/ms
1 fluid ounce per seconds = 0.00003125 quarts per millisecond.
Real-world example
60 fl oz/s × 0.00003125 = 0.001875 qt/ms
60 fluid ounce per seconds = 0.001875 quarts per millisecond.

Frequently asked questions
How many quarts per millisecond are in 1 fluid ounce per seconds?
1 fluid ounce per seconds equals 0.00003125 quarts per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert fluid ounce per seconds to quart per millisecond?
Multiply the fluid ounce per seconds value by 0.00003125. The converter above does this instantly to whatever precision you set.
How do I convert quart per millisecond back to fluid ounce per seconds?
Use the reverse factor: 1 quart per millisecond equals 32,000 fluid ounce per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a fluid ounce per seconds?
Fluid ounce per Seconds (fl oz/s) is a unit of flow rate.
What is a quart per millisecond?
Quart per Millisecond (qt/ms) is a unit of flow rate.
Is the fluid ounce per seconds to quart per millisecond conversion exact?
Yes. Both fluid ounce per seconds and quart per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.00003125 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.
