About Converting Gallon per Days to Cubic Meter per Years
Gallon per Days and Cubic Meter 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
cubic meter per years = gallon per days × 1.38259326352
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 cubic meter per years equals 3.168874e-8 base units, so dividing one by the other gives the direct gallon per days-to-cubic meter per years factor of 1.38259326352.
Simple example
1 gal/d × 1.382593264 = 1.382593264 m3/yr
1 gallon per days = 1.382593264 cubic meter per years.
Real-world example
60 gal/d × 1.382593264 = 82.95559581 m3/yr
60 gallon per days = 82.95559581 cubic meter per years.

Frequently asked questions
How many cubic meter per years are in 1 gallon per days?
1 gallon per days equals 1.382593264 cubic meter per years, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per days to cubic meter per years?
Multiply the gallon per days value by 1.382593264. The converter above does this instantly to whatever precision you set.
How do I convert cubic meter per years back to gallon per days?
Use the reverse factor: 1 cubic meter per years equals 0.7232785132 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 cubic meter per years?
Cubic Meter per Years (m3/yr) is a unit of flow rate.
Is the gallon per days to cubic meter per years conversion exact?
Yes. Both gallon per days and cubic meter per years are defined by fixed standards rather than physical artifacts, so the factor of 1.382593264 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.
