About Converting Cup per Hours to Cubic Millimeter per Seconds
Cup per Hours and Cubic Millimeter 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
cubic millimeter per seconds = cup per hours × 65.7189545833
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 cubic millimeter per seconds equals 1e-9 base units, so dividing one by the other gives the direct cup per hours-to-cubic millimeter per seconds factor of 65.7189545833.
Simple example
1 cup/h × 65.71895458 = 65.71895458 mm3/s
1 cup per hours = 65.71895458 cubic millimeter per seconds.
Real-world example
60 cup/h × 65.71895458 = 3,943.137275 mm3/s
60 cup per hours = 3,943.137275 cubic millimeter per seconds.

Frequently asked questions
How many cubic millimeter per seconds are in 1 cup per hours?
1 cup per hours equals 65.71895458 cubic millimeter per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cup per hours to cubic millimeter per seconds?
Multiply the cup per hours value by 65.71895458. The converter above does this instantly to whatever precision you set.
How do I convert cubic millimeter per seconds back to cup per hours?
Use the reverse factor: 1 cubic millimeter per seconds equals 0.0152163102 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 cubic millimeter per seconds?
Cubic Millimeter per Seconds (mm3/s) is a unit of flow rate.
Is the cup per hours to cubic millimeter per seconds conversion exact?
Yes. Both cup per hours and cubic millimeter per seconds are defined by fixed standards rather than physical artifacts, so the factor of 65.71895458 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.
