About Converting Cup per Hours to Cubic inches per Millisecond
Cup per Hours and Cubic inch 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
cubic inches per millisecond = cup per hours × 0.00000401041666667
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 inch per millisecond equals 0.016387064 base units, so dividing one by the other gives the direct cup per hours-to-cubic inch per millisecond factor of 0.00000401041666667.
Simple example
1 cup/h × 0.000004010416667 = 0.0000040104 in3/ms
1 cup per hours = 0.0000040104 cubic inches per millisecond.
Real-world example
60 cup/h × 0.000004010416667 = 0.000240625 in3/ms
60 cup per hours = 0.000240625 cubic inches per millisecond.

Frequently asked questions
How many cubic inches per millisecond are in 1 cup per hours?
1 cup per hours equals 0.0000040104 cubic inches per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert cup per hours to cubic inch per millisecond?
Multiply the cup per hours value by 0.000004010416667. The converter above does this instantly to whatever precision you set.
How do I convert cubic inch per millisecond back to cup per hours?
Use the reverse factor: 1 cubic inch per millisecond equals 249,350.6494 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 inch per millisecond?
Cubic inch per Millisecond (in3/ms) is a unit of flow rate.
Is the cup per hours to cubic inch per millisecond conversion exact?
Yes. Both cup per hours and cubic inch per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.000004010416667 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.
