About Converting Cubic Millimeter per Hours to Cubic foot per Hours
Cubic Millimeter per Hours and Cubic foot per Hours 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 foot per hours = cubic millimeter per hours × 3.531467e-8
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic millimeter per hours equals 2.777778e-13 base units, and 1 cubic foot per hours equals 0.00000786579072 base units, so dividing one by the other gives the direct cubic millimeter per hours-to-cubic foot per hours factor of 3.531467e-8.
Simple example
1 mm3/h × 3.531467e-8 = 3.531467e-8 ft3/h
1 cubic millimeter per hours = 3.531467e-8 cubic foot per hours.
Real-world example
60 mm3/h × 3.531467e-8 = 0.0000021189 ft3/h
60 cubic millimeter per hours = 0.0000021189 cubic foot per hours.

Frequently asked questions
How many cubic foot per hours are in 1 cubic millimeter per hours?
1 cubic millimeter per hours equals 3.531467e-8 cubic foot per hours, using the exact defined conversion factor rather than an estimate.
How do I convert cubic millimeter per hours to cubic foot per hours?
Multiply the cubic millimeter per hours value by 3.531467e-8. The converter above does this instantly to whatever precision you set.
How do I convert cubic foot per hours back to cubic millimeter per hours?
Use the reverse factor: 1 cubic foot per hours equals 28,316,846.59 cubic millimeter per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic millimeter per hours?
Cubic Millimeter per Hours (mm3/h) is a unit of flow rate.
What is a cubic foot per hours?
Cubic foot per Hours (ft3/h) is a unit of flow rate.
Is the cubic millimeter per hours to cubic foot per hours conversion exact?
Yes. Both cubic millimeter per hours and cubic foot per hours are defined by fixed standards rather than physical artifacts, so the factor of 3.531467e-8 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.
