About Converting Cup per Hours to Cups per Millisecond
Cup 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 = cup per hours × 2.777778e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 cup per hours equals 6.571895e-8 base units, and 1 cup per millisecond equals 0.2365882365 base units, so dividing one by the other gives the direct cup per hours-to-cup per millisecond factor of 2.777778e-7.
Simple example
1 cup/h × 2.777778e-7 = 2.777778e-7 cup/ms
1 cup per hours = 2.777778e-7 cups per millisecond.
Real-world example
60 cup/h × 2.777778e-7 = 0.0000166667 cup/ms
60 cup per hours = 0.0000166667 cups per millisecond.
Conversion table

Frequently asked questions
How many cups per millisecond are in 1 cup per hours?
1 cup per hours equals 2.777778e-7 cups per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert cup per hours to cup per millisecond?
Multiply the cup per hours value by 2.777778e-7. The converter above does this instantly to whatever precision you set.
How do I convert cup per millisecond back to cup per hours?
Use the reverse factor: 1 cup per millisecond equals 3,600,000 cup per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a cup per hours?
Cup per Hours (cup/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 cup per hours to cup per millisecond conversion exact?
Yes. Both cup per hours and cup per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 2.777778e-7 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.
