About Converting Microliter per Days to Gallon per Days
Microliter per Days and Gallon 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
gallon per days = microliter per days × 2.641721e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 microliter per days equals 1.157407e-14 base units, and 1 gallon per days equals 4.381264e-8 base units, so dividing one by the other gives the direct microliter per days-to-gallon per days factor of 2.641721e-7.
Simple example
1 uL/d × 2.641721e-7 = 2.641721e-7 gal/d
1 microliter per days = 2.641721e-7 gallon per days.
Real-world example
60 uL/d × 2.641721e-7 = 0.0000158503 gal/d
60 microliter per days = 0.0000158503 gallon per days.

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