About Converting Gallon per Seconds to Cubic Millimeters per Millisecond
Gallon per Seconds 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 = gallon per seconds × 3785.411784
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per seconds equals 0.003785411784 base units, and 1 cubic millimeter per millisecond equals 0.000001 base units, so dividing one by the other gives the direct gallon per seconds-to-cubic millimeter per millisecond factor of 3785.411784.
Simple example
1 gal/s × 3785.411784 = 3,785.411784 mm3/ms
1 gallon per seconds = 3,785.411784 cubic millimeters per millisecond.
Real-world example
60 gal/s × 3785.411784 = 227,124.707 mm3/ms
60 gallon per seconds = 227,124.707 cubic millimeters per millisecond.

Frequently asked questions
How many cubic millimeters per millisecond are in 1 gallon per seconds?
1 gallon per seconds equals 3,785.411784 cubic millimeters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per seconds to cubic millimeter per millisecond?
Multiply the gallon per seconds value by 3785.411784. The converter above does this instantly to whatever precision you set.
How do I convert cubic millimeter per millisecond back to gallon per seconds?
Use the reverse factor: 1 cubic millimeter per millisecond equals 0.0002641721 gallon per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per seconds?
Gallon per Seconds (gal/s) 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 seconds to cubic millimeter per millisecond conversion exact?
Yes. Both gallon per seconds and cubic millimeter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 3785.411784 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.
