About Converting Gallons per Millisecond to Cubic feet per Millisecond
Gallon per Millisecond 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 = gallons per millisecond × 0.133680555556
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 millisecond equals 28.316846592 base units, so dividing one by the other gives the direct gallon per millisecond-to-cubic foot per millisecond factor of 0.133680555556.
Simple example
1 gal/ms × 0.1336805556 = 0.1336805556 ft3/ms
1 gallon per millisecond = 0.1336805556 cubic feet per millisecond.
Real-world example
60 gal/ms × 0.1336805556 = 8.020833333 ft3/ms
60 gallons per millisecond = 8.020833333 cubic feet per millisecond.

Frequently asked questions
How many cubic feet per millisecond are in 1 gallon per millisecond?
1 gallon per millisecond equals 0.1336805556 cubic feet per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per millisecond to cubic foot per millisecond?
Multiply the gallon per millisecond value by 0.1336805556. The converter above does this instantly to whatever precision you set.
How do I convert cubic foot per millisecond back to gallon per millisecond?
Use the reverse factor: 1 cubic foot per millisecond equals 7.480519481 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 millisecond?
Cubic foot per Millisecond (ft3/ms) is a unit of flow rate.
Is the gallon per millisecond to cubic foot per millisecond conversion exact?
Yes. Both gallon per millisecond and cubic foot per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.1336805556 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.
