About Converting Cubic Meters per Millisecond to Gallon per Minutes
Cubic Meter per Millisecond and Gallon 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
gallon per minutes = cubic meters per millisecond × 15850323.1415
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic meter per millisecond equals 1000 base units, and 1 gallon per minutes equals 0.0000630901964 base units, so dividing one by the other gives the direct cubic meter per millisecond-to-gallon per minutes factor of 15850323.1415.
Simple example
1 m3/ms × 15850323.14 = 15,850,323.14 gal/min
1 cubic meter per millisecond = 15,850,323.14 gallon per minutes.
Real-world example
60 m3/ms × 15850323.14 = 951,019,388.5 gal/min
60 cubic meters per millisecond = 951,019,388.5 gallon per minutes.

Frequently asked questions
How many gallon per minutes are in 1 cubic meter per millisecond?
1 cubic meter per millisecond equals 15,850,323.14 gallon per minutes, using the exact defined conversion factor rather than an estimate.
How do I convert cubic meter per millisecond to gallon per minutes?
Multiply the cubic meter per millisecond value by 15850323.14. The converter above does this instantly to whatever precision you set.
How do I convert gallon per minutes back to cubic meter per millisecond?
Use the reverse factor: 1 gallon per minutes equals 6.30902e-8 cubic meters per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic meter per millisecond?
Cubic Meter per Millisecond (m3/ms) is a unit of flow rate.
What is a gallon per minutes?
Gallon per Minutes (gal/min) measures volumetric flow rate. The standard US unit for pump, plumbing, and irrigation flow-rate specifications. It is classified as a US customary flow-rate unit.
Is the cubic meter per millisecond to gallon per minutes conversion exact?
Yes. Both cubic meter per millisecond and gallon per minutes are defined by fixed standards rather than physical artifacts, so the factor of 15850323.14 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.
