About Converting Cubic inch per Hours to Cubic Millimeter per Years
Cubic inch per Hours and Cubic Millimeter per Years 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 years = cubic inch per hours × 143646053.352
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 years equals 3.168874e-17 base units, so dividing one by the other gives the direct cubic inch per hours-to-cubic millimeter per years factor of 143646053.352.
Simple example
1 in3/h × 143646053.4 = 143,646,053.4 mm3/yr
1 cubic inch per hours = 143,646,053.4 cubic millimeter per years.
Real-world example
60 in3/h × 143646053.4 = 8,618,763,201 mm3/yr
60 cubic inch per hours = 8,618,763,201 cubic millimeter per years.

Frequently asked questions
How many cubic millimeter per years are in 1 cubic inch per hours?
1 cubic inch per hours equals 143,646,053.4 cubic millimeter per years, using the exact defined conversion factor rather than an estimate.
How do I convert cubic inch per hours to cubic millimeter per years?
Multiply the cubic inch per hours value by 143646053.4. The converter above does this instantly to whatever precision you set.
How do I convert cubic millimeter per years back to cubic inch per hours?
Use the reverse factor: 1 cubic millimeter per years equals 6.961556e-9 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 years?
Cubic Millimeter per Years (mm3/yr) is a unit of flow rate.
Is the cubic inch per hours to cubic millimeter per years conversion exact?
Yes. Both cubic inch per hours and cubic millimeter per years are defined by fixed standards rather than physical artifacts, so the factor of 143646053.4 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.
