About Converting Microliters per Millisecond to Gallons per Millisecond
Microliter 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 = microliters per millisecond × 2.641721e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 microliter per millisecond equals 0.000001 base units, and 1 gallon per millisecond equals 3.785411784 base units, so dividing one by the other gives the direct microliter per millisecond-to-gallon per millisecond factor of 2.641721e-7.
Simple example
1 uL/ms × 2.641721e-7 = 2.641721e-7 gal/ms
1 microliter per millisecond = 2.641721e-7 gallons per millisecond.
Real-world example
60 uL/ms × 2.641721e-7 = 0.0000158503 gal/ms
60 microliters per millisecond = 0.0000158503 gallons per millisecond.

Frequently asked questions
How many gallons per millisecond are in 1 microliter per millisecond?
1 microliter per millisecond equals 2.641721e-7 gallons per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert microliter per millisecond to gallon per millisecond?
Multiply the microliter per millisecond value by 2.641721e-7. The converter above does this instantly to whatever precision you set.
How do I convert gallon per millisecond back to microliter per millisecond?
Use the reverse factor: 1 gallon per millisecond equals 3,785,411.784 microliters per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a microliter per millisecond?
Microliter per Millisecond (uL/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 microliter per millisecond to gallon per millisecond conversion exact?
Yes. Both microliter per millisecond and gallon per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 2.641721e-7 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.
