About Converting Imperial quart per Hours to Cups per Millisecond
Imperial quart per Hours and Cup 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
cups per millisecond = imperial quart per hours × 0.00000133438880612
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial quart per hours equals 3.157007e-7 base units, and 1 cup per millisecond equals 0.2365882365 base units, so dividing one by the other gives the direct imperial quart per hours-to-cup per millisecond factor of 0.00000133438880612.
Simple example
1 imp qt/h × 0.000001334388806 = 0.0000013344 cup/ms
1 imperial quart per hours = 0.0000013344 cups per millisecond.
Real-world example
60 imp qt/h × 0.000001334388806 = 0.0000800633 cup/ms
60 imperial quart per hours = 0.0000800633 cups per millisecond.

Frequently asked questions
How many cups per millisecond are in 1 imperial quart per hours?
1 imperial quart per hours equals 0.0000013344 cups per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert imperial quart per hours to cup per millisecond?
Multiply the imperial quart per hours value by 0.000001334388806. The converter above does this instantly to whatever precision you set.
How do I convert cup per millisecond back to imperial quart per hours?
Use the reverse factor: 1 cup per millisecond equals 749,406.7662 imperial quart per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial quart per hours?
Imperial quart per Hours (imp qt/h) is a unit of flow rate.
What is a cup per millisecond?
Cup per Millisecond (cup/ms) is a unit of flow rate.
Is the imperial quart per hours to cup per millisecond conversion exact?
Yes. Both imperial quart per hours and cup per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.000001334388806 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.
