About Converting Cubic inch per Hours to Cubic Millimeter per Minutes
Cubic inch per Hours and Cubic Millimeter per Minutes 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 minutes = cubic inch per hours × 273.117733333
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 minutes equals 1.666667e-11 base units, so dividing one by the other gives the direct cubic inch per hours-to-cubic millimeter per minutes factor of 273.117733333.
Simple example
1 in3/h × 273.1177333 = 273.1177333 mm3/min
1 cubic inch per hours = 273.1177333 cubic millimeter per minutes.
Real-world example
60 in3/h × 273.1177333 = 16,387.064 mm3/min
60 cubic inch per hours = 16,387.064 cubic millimeter per minutes.

Frequently asked questions
How many cubic millimeter per minutes are in 1 cubic inch per hours?
1 cubic inch per hours equals 273.1177333 cubic millimeter per minutes, using the exact defined conversion factor rather than an estimate.
How do I convert cubic inch per hours to cubic millimeter per minutes?
Multiply the cubic inch per hours value by 273.1177333. The converter above does this instantly to whatever precision you set.
How do I convert cubic millimeter per minutes back to cubic inch per hours?
Use the reverse factor: 1 cubic millimeter per minutes equals 0.0036614246 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 minutes?
Cubic Millimeter per Minutes (mm3/min) is a unit of flow rate.
Is the cubic inch per hours to cubic millimeter per minutes conversion exact?
Yes. Both cubic inch per hours and cubic millimeter per minutes are defined by fixed standards rather than physical artifacts, so the factor of 273.1177333 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.
