About Converting Gallon per Days to Microliter per Days
Gallon per Days and Microliter per Days 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 days = gallon per days × 3785411.784
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 days equals 1.157407e-14 base units, so dividing one by the other gives the direct gallon per days-to-microliter per days factor of 3785411.784.
Simple example
1 gal/d × 3785411.784 = 3,785,411.784 uL/d
1 gallon per days = 3,785,411.784 microliter per days.
Real-world example
60 gal/d × 3785411.784 = 227,124,707 uL/d
60 gallon per days = 227,124,707 microliter per days.

Frequently asked questions
How many microliter per days are in 1 gallon per days?
1 gallon per days equals 3,785,411.784 microliter per days, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per days to microliter per days?
Multiply the gallon per days value by 3785411.784. The converter above does this instantly to whatever precision you set.
How do I convert microliter per days back to gallon per days?
Use the reverse factor: 1 microliter per days equals 2.641721e-7 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 days?
Microliter per Days (uL/d) is a unit of flow rate.
Is the gallon per days to microliter per days conversion exact?
Yes. Both gallon per days and microliter per days are defined by fixed standards rather than physical artifacts, so the factor of 3785411.784 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.
