About Converting Cubic inch per Hours to Cubic Millimeter per Seconds
Cubic inch 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 = cubic inch per hours × 4.55196222222
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic inch per hours equals 4.551962e-9 base units, and 1 cubic millimeter per seconds equals 1e-9 base units, so dividing one by the other gives the direct cubic inch per hours-to-cubic millimeter per seconds factor of 4.55196222222.
Simple example
1 in3/h × 4.551962222 = 4.551962222 mm3/s
1 cubic inch per hours = 4.551962222 cubic millimeter per seconds.
Real-world example
60 in3/h × 4.551962222 = 273.1177333 mm3/s
60 cubic inch per hours = 273.1177333 cubic millimeter per seconds.

Frequently asked questions
How many cubic millimeter per seconds are in 1 cubic inch per hours?
1 cubic inch per hours equals 4.551962222 cubic millimeter per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cubic inch per hours to cubic millimeter per seconds?
Multiply the cubic inch per hours value by 4.551962222. The converter above does this instantly to whatever precision you set.
How do I convert cubic millimeter per seconds back to cubic inch per hours?
Use the reverse factor: 1 cubic millimeter per seconds equals 0.2196854787 cubic inch per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic inch per hours?
Cubic inch per Hours (in3/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 cubic inch per hours to cubic millimeter per seconds conversion exact?
Yes. Both cubic inch per hours and cubic millimeter per seconds are defined by fixed standards rather than physical artifacts, so the factor of 4.551962222 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.
