About Converting Gallon per Days to Megaliter per Years
Gallon per Days and Megaliter per Years 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 years = gallon per days × 0.00138259326352
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 years equals 0.0000316887385068 base units, so dividing one by the other gives the direct gallon per days-to-megaliter per years factor of 0.00138259326352.
Simple example
1 gal/d × 0.001382593264 = 0.0013825933 ML/yr
1 gallon per days = 0.0013825933 megaliter per years.
Real-world example
60 gal/d × 0.001382593264 = 0.0829555958 ML/yr
60 gallon per days = 0.0829555958 megaliter per years.

Frequently asked questions
How many megaliter per years are in 1 gallon per days?
1 gallon per days equals 0.0013825933 megaliter per years, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per days to megaliter per years?
Multiply the gallon per days value by 0.001382593264. The converter above does this instantly to whatever precision you set.
How do I convert megaliter per years back to gallon per days?
Use the reverse factor: 1 megaliter per years equals 723.2785132 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 years?
Megaliter per Years (ML/yr) is a unit of flow rate.
Is the gallon per days to megaliter per years conversion exact?
Yes. Both gallon per days and megaliter per years are defined by fixed standards rather than physical artifacts, so the factor of 0.001382593264 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.
