About Converting Microliters per Millisecond to Gallon per Seconds
Microliter per Millisecond and Gallon per Seconds 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 seconds = microliters per millisecond × 0.000264172052358
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 seconds equals 0.003785411784 base units, so dividing one by the other gives the direct microliter per millisecond-to-gallon per seconds factor of 0.000264172052358.
Simple example
1 uL/ms × 0.0002641720524 = 0.0002641721 gal/s
1 microliter per millisecond = 0.0002641721 gallon per seconds.
Real-world example
60 uL/ms × 0.0002641720524 = 0.0158503231 gal/s
60 microliters per millisecond = 0.0158503231 gallon per seconds.

Frequently asked questions
How many gallon per seconds are in 1 microliter per millisecond?
1 microliter per millisecond equals 0.0002641721 gallon per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert microliter per millisecond to gallon per seconds?
Multiply the microliter per millisecond value by 0.0002641720524. The converter above does this instantly to whatever precision you set.
How do I convert gallon per seconds back to microliter per millisecond?
Use the reverse factor: 1 gallon per seconds equals 3,785.411784 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 seconds?
Gallon per Seconds (gal/s) is a unit of flow rate.
Is the microliter per millisecond to gallon per seconds conversion exact?
Yes. Both microliter per millisecond and gallon per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.0002641720524 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.
