About Converting Gallons per Millisecond to Microliter per Seconds
Gallon per Millisecond and Microliter 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
microliter per seconds = gallons per millisecond × 3785411784
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per millisecond equals 3.785411784 base units, and 1 microliter per seconds equals 1e-9 base units, so dividing one by the other gives the direct gallon per millisecond-to-microliter per seconds factor of 3785411784.
Simple example
1 gal/ms × 3785411784 = 3,785,411,784 uL/s
1 gallon per millisecond = 3,785,411,784 microliter per seconds.
Real-world example
60 gal/ms × 3785411784 = 227,124,707,000 uL/s
60 gallons per millisecond = 227,124,707,000 microliter per seconds.

Reverse conversion: Microliter per Seconds to Gallon per Millisecond
1 uL/s × 2.641721e-10 = 2.641721e-10 gal/ms
1 microliter per seconds = 2.641721e-10 gallons per millisecond.
gallons per millisecond = microliter per seconds × 2.641721e-10

Frequently asked questions
How many microliter per seconds are in 1 gallon per millisecond?
1 gallon per millisecond equals 3,785,411,784 microliter per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per millisecond to microliter per seconds?
Multiply the gallon per millisecond value by 3785411784. The converter above does this instantly to whatever precision you set.
How do I convert microliter per seconds back to gallon per millisecond?
Use the reverse factor: 1 microliter per seconds equals 2.641721e-10 gallons per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per millisecond?
Gallon per Millisecond (gal/ms) is a unit of flow rate.
What is a microliter per seconds?
Microliter per Seconds (uL/s) is a unit of flow rate.
Is the gallon per millisecond to microliter per seconds conversion exact?
Yes. Both gallon per millisecond and microliter per seconds are defined by fixed standards rather than physical artifacts, so the factor of 3785411784 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.
