About Converting Liter per Hours to Cups per Millisecond
Liter 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 = liter per hours × 0.00000117409801048
This factor comes from each unit's defined relationship to the category's base unit: 1 liter per hours equals 2.777778e-7 base units, and 1 cup per millisecond equals 0.2365882365 base units, so dividing one by the other gives the direct liter per hours-to-cup per millisecond factor of 0.00000117409801048.
Simple example
1 L/h × 0.00000117409801 = 0.0000011741 cup/ms
1 liter per hours = 0.0000011741 cups per millisecond.
Real-world example
60 L/h × 0.00000117409801 = 0.0000704459 cup/ms
60 liter per hours = 0.0000704459 cups per millisecond.

Frequently asked questions
How many cups per millisecond are in 1 liter per hours?
1 liter per hours equals 0.0000011741 cups per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert liter per hours to cup per millisecond?
Multiply the liter per hours value by 0.00000117409801. The converter above does this instantly to whatever precision you set.
How do I convert cup per millisecond back to liter per hours?
Use the reverse factor: 1 cup per millisecond equals 851,717.6514 liter per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a liter per hours?
Liter per Hours (L/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 liter per hours to cup per millisecond conversion exact?
Yes. Both liter per hours and cup per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.00000117409801 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.
