About Converting Cubic foot per Hours to Cubic feet per Millisecond
Cubic foot per Hours and Cubic foot per Millisecond 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 feet per millisecond = cubic foot per hours × 2.777778e-7
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 foot per millisecond equals 28.316846592 base units, so dividing one by the other gives the direct cubic foot per hours-to-cubic foot per millisecond factor of 2.777778e-7.
Simple example
1 ft3/h × 2.777778e-7 = 2.777778e-7 ft3/ms
1 cubic foot per hours = 2.777778e-7 cubic feet per millisecond.
Real-world example
60 ft3/h × 2.777778e-7 = 0.0000166667 ft3/ms
60 cubic foot per hours = 0.0000166667 cubic feet per millisecond.

Frequently asked questions
How many cubic feet per millisecond are in 1 cubic foot per hours?
1 cubic foot per hours equals 2.777778e-7 cubic feet per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert cubic foot per hours to cubic foot per millisecond?
Multiply the cubic foot per hours value by 2.777778e-7. The converter above does this instantly to whatever precision you set.
How do I convert cubic foot per millisecond back to cubic foot per hours?
Use the reverse factor: 1 cubic foot per millisecond equals 3,600,000 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 foot per millisecond?
Cubic foot per Millisecond (ft3/ms) is a unit of flow rate.
Is the cubic foot per hours to cubic foot per millisecond conversion exact?
Yes. Both cubic foot per hours and cubic foot per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 2.777778e-7 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.
