About Converting Gallons per Millisecond to Cubic foot per Minutes
Gallon per Millisecond and Cubic foot 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 foot per minutes = gallons per millisecond × 8020.83333333
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per millisecond equals 3.785411784 base units, and 1 cubic foot per minutes equals 0.0004719474432 base units, so dividing one by the other gives the direct gallon per millisecond-to-cubic foot per minutes factor of 8020.83333333.
Simple example
1 gal/ms × 8020.833333 = 8,020.833333 ft3/min
1 gallon per millisecond = 8,020.833333 cubic foot per minutes.
Real-world example
60 gal/ms × 8020.833333 = 481,250 ft3/min
60 gallons per millisecond = 481,250 cubic foot per minutes.

Frequently asked questions
How many cubic foot per minutes are in 1 gallon per millisecond?
1 gallon per millisecond equals 8,020.833333 cubic foot per minutes, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per millisecond to cubic foot per minutes?
Multiply the gallon per millisecond value by 8020.833333. The converter above does this instantly to whatever precision you set.
How do I convert cubic foot per minutes back to gallon per millisecond?
Use the reverse factor: 1 cubic foot per minutes equals 0.0001246753 gallons per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per millisecond?
Gallon per Millisecond (gal/ms) is a unit of flow rate.
What is a cubic foot per minutes?
Cubic foot per Minutes (ft3/min) measures volumetric flow rate. One cubic foot of volume passing a point every minute. It is classified as a US customary flow-rate unit.
Is the gallon per millisecond to cubic foot per minutes conversion exact?
Yes. Both gallon per millisecond and cubic foot per minutes are defined by fixed standards rather than physical artifacts, so the factor of 8020.833333 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.
