About Converting Gallons per Millisecond to Cubic Millimeters per Millisecond
Gallon per Millisecond and Cubic Millimeter 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 millimeters per millisecond = gallons per millisecond × 3785411.784
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 millimeter per millisecond equals 0.000001 base units, so dividing one by the other gives the direct gallon per millisecond-to-cubic millimeter per millisecond factor of 3785411.784.
Simple example
1 gal/ms × 3785411.784 = 3,785,411.784 mm3/ms
1 gallon per millisecond = 3,785,411.784 cubic millimeters per millisecond.
Real-world example
60 gal/ms × 3785411.784 = 227,124,707 mm3/ms
60 gallons per millisecond = 227,124,707 cubic millimeters per millisecond.

Frequently asked questions
How many cubic millimeters per millisecond are in 1 gallon per millisecond?
1 gallon per millisecond equals 3,785,411.784 cubic millimeters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per millisecond to cubic millimeter per millisecond?
Multiply the gallon per millisecond value by 3785411.784. The converter above does this instantly to whatever precision you set.
How do I convert cubic millimeter per millisecond back to gallon per millisecond?
Use the reverse factor: 1 cubic millimeter per millisecond equals 2.641721e-7 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 millimeter per millisecond?
Cubic Millimeter per Millisecond (mm3/ms) is a unit of flow rate.
Is the gallon per millisecond to cubic millimeter per millisecond conversion exact?
Yes. Both gallon per millisecond and cubic millimeter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 3785411.784 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.
