About Converting Cubic foot per Hours to Cubic Millimeter per Seconds
Cubic foot 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 foot per hours × 7865.79072
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic foot per hours equals 0.00000786579072 base units, and 1 cubic millimeter per seconds equals 1e-9 base units, so dividing one by the other gives the direct cubic foot per hours-to-cubic millimeter per seconds factor of 7865.79072.
Simple example
1 ft3/h × 7865.79072 = 7,865.79072 mm3/s
1 cubic foot per hours = 7,865.79072 cubic millimeter per seconds.
Real-world example
60 ft3/h × 7865.79072 = 471,947.4432 mm3/s
60 cubic foot per hours = 471,947.4432 cubic millimeter per seconds.

Frequently asked questions
How many cubic millimeter per seconds are in 1 cubic foot per hours?
1 cubic foot per hours equals 7,865.79072 cubic millimeter per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cubic foot per hours to cubic millimeter per seconds?
Multiply the cubic foot per hours value by 7865.79072. The converter above does this instantly to whatever precision you set.
How do I convert cubic millimeter per seconds back to cubic foot per hours?
Use the reverse factor: 1 cubic millimeter per seconds equals 0.0001271328 cubic foot per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic foot per hours?
Cubic foot per Hours (ft3/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 foot per hours to cubic millimeter per seconds conversion exact?
Yes. Both cubic foot per hours and cubic millimeter per seconds are defined by fixed standards rather than physical artifacts, so the factor of 7865.79072 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.
