About Converting Imperial fluid ounce per Hours to Quarts per Millisecond
Imperial fluid ounce per Hours 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 = imperial fluid ounce per hours × 8.33993e-9
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial fluid ounce per hours equals 7.892517e-9 base units, and 1 quart per millisecond equals 0.946352946 base units, so dividing one by the other gives the direct imperial fluid ounce per hours-to-quart per millisecond factor of 8.33993e-9.
Simple example
1 imp fl oz/h × 8.33993e-9 = 8.33993e-9 qt/ms
1 imperial fluid ounce per hours = 8.33993e-9 quarts per millisecond.
Real-world example
60 imp fl oz/h × 8.33993e-9 = 5.003958e-7 qt/ms
60 imperial fluid ounce per hours = 5.003958e-7 quarts per millisecond.

How do I convert quart per millisecond back to imperial fluid ounce per hours?
Use the reverse factor: 1 quart per millisecond equals 119,905,082.6 imperial fluid ounce per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial fluid ounce per hours?
Imperial fluid ounce per Hours (imp fl oz/h) 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 imperial fluid ounce per hours to quart per millisecond conversion exact?
Yes. Both imperial fluid ounce per hours and quart per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 8.33993e-9 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.
