About Converting Liters per Millisecond to Cup per Seconds
Liter per Millisecond and Cup per Seconds 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
cup per seconds = liters per millisecond × 4226.75283773
This factor comes from each unit's defined relationship to the category's base unit: 1 liter per millisecond equals 1 base unit, and 1 cup per seconds equals 0.0002365882365 base units, so dividing one by the other gives the direct liter per millisecond-to-cup per seconds factor of 4226.75283773.
Simple example
1 L/ms × 4226.752838 = 4,226.752838 cup/s
1 liter per millisecond = 4,226.752838 cup per seconds.
Real-world example
60 L/ms × 4226.752838 = 253,605.1703 cup/s
60 liters per millisecond = 253,605.1703 cup per seconds.

Frequently asked questions
How many cup per seconds are in 1 liter per millisecond?
1 liter per millisecond equals 4,226.752838 cup per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert liter per millisecond to cup per seconds?
Multiply the liter per millisecond value by 4226.752838. The converter above does this instantly to whatever precision you set.
How do I convert cup per seconds back to liter per millisecond?
Use the reverse factor: 1 cup per seconds equals 0.0002365882 liters per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a liter per millisecond?
Liter per Millisecond (L/ms) is a unit of flow rate.
What is a cup per seconds?
Cup per Seconds (cup/s) is a unit of flow rate.
Is the liter per millisecond to cup per seconds conversion exact?
Yes. Both liter per millisecond and cup per seconds are defined by fixed standards rather than physical artifacts, so the factor of 4226.752838 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.
