About Converting Gallon per Days to Microliters per Millisecond
Gallon per Days and Microliter 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
microliters per millisecond = gallon per days × 0.0438126363889
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per days equals 4.381264e-8 base units, and 1 microliter per millisecond equals 0.000001 base units, so dividing one by the other gives the direct gallon per days-to-microliter per millisecond factor of 0.0438126363889.
Simple example
1 gal/d × 0.04381263639 = 0.0438126364 uL/ms
1 gallon per days = 0.0438126364 microliters per millisecond.
Real-world example
60 gal/d × 0.04381263639 = 2.628758183 uL/ms
60 gallon per days = 2.628758183 microliters per millisecond.

Frequently asked questions
How many microliters per millisecond are in 1 gallon per days?
1 gallon per days equals 0.0438126364 microliters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per days to microliter per millisecond?
Multiply the gallon per days value by 0.04381263639. The converter above does this instantly to whatever precision you set.
How do I convert microliter per millisecond back to gallon per days?
Use the reverse factor: 1 microliter per millisecond equals 22.82446532 gallon per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per days?
Gallon per Days (gal/d) is a unit of flow rate.
What is a microliter per millisecond?
Microliter per Millisecond (uL/ms) is a unit of flow rate.
Is the gallon per days to microliter per millisecond conversion exact?
Yes. Both gallon per days and microliter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.04381263639 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.
