About Converting Gallon per Days to Megaliter per Days
Gallon per Days and Megaliter 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
megaliter per days = gallon per days × 0.000003785411784
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 megaliter per days equals 0.0115740740741 base units, so dividing one by the other gives the direct gallon per days-to-megaliter per days factor of 0.000003785411784.
Simple example
1 gal/d × 0.000003785411784 = 0.0000037854 ML/d
1 gallon per days = 0.0000037854 megaliter per days.
Real-world example
60 gal/d × 0.000003785411784 = 0.0002271247 ML/d
60 gallon per days = 0.0002271247 megaliter per days.

How do I convert megaliter per days back to gallon per days?
Use the reverse factor: 1 megaliter per days equals 264,172.0524 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 megaliter per days?
Megaliter per Days (ML/d) is a unit of flow rate.
Is the gallon per days to megaliter per days conversion exact?
Yes. Both gallon per days and megaliter per days are defined by fixed standards rather than physical artifacts, so the factor of 0.000003785411784 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.
