About Converting Cubic Meters per Millisecond to Gallons per Millisecond
Cubic Meter per Millisecond and Gallon 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
gallons per millisecond = cubic meters per millisecond × 264.172052358
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 millisecond equals 3.785411784 base units, so dividing one by the other gives the direct cubic meter per millisecond-to-gallon per millisecond factor of 264.172052358.
Simple example
1 m3/ms × 264.1720524 = 264.1720524 gal/ms
1 cubic meter per millisecond = 264.1720524 gallons per millisecond.
Real-world example
60 m3/ms × 264.1720524 = 15,850.32314 gal/ms
60 cubic meters per millisecond = 15,850.32314 gallons per millisecond.

Frequently asked questions
How many gallons per millisecond are in 1 cubic meter per millisecond?
1 cubic meter per millisecond equals 264.1720524 gallons per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert cubic meter per millisecond to gallon per millisecond?
Multiply the cubic meter per millisecond value by 264.1720524. The converter above does this instantly to whatever precision you set.
How do I convert gallon per millisecond back to cubic meter per millisecond?
Use the reverse factor: 1 gallon per millisecond equals 0.0037854118 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 millisecond?
Gallon per Millisecond (gal/ms) is a unit of flow rate.
Is the cubic meter per millisecond to gallon per millisecond conversion exact?
Yes. Both cubic meter per millisecond and gallon per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 264.1720524 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.
