About Converting Cubic Meter per Years to Gallon per Years
Cubic Meter per Years and Gallon 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
gallon per years = cubic meter per years × 264.172052358
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic meter per years equals 3.168874e-8 base units, and 1 gallon per years equals 1.199549e-10 base units, so dividing one by the other gives the direct cubic meter per years-to-gallon per years factor of 264.172052358.
Simple example
1 m3/yr × 264.1720524 = 264.1720524 gal/yr
1 cubic meter per years = 264.1720524 gallon per years.
Real-world example
60 m3/yr × 264.1720524 = 15,850.32314 gal/yr
60 cubic meter per years = 15,850.32314 gallon per years.

Frequently asked questions
How many gallon per years are in 1 cubic meter per years?
1 cubic meter per years equals 264.1720524 gallon per years, using the exact defined conversion factor rather than an estimate.
How do I convert cubic meter per years to gallon per years?
Multiply the cubic meter per years value by 264.1720524. The converter above does this instantly to whatever precision you set.
How do I convert gallon per years back to cubic meter per years?
Use the reverse factor: 1 gallon per years equals 0.0037854118 cubic meter per years. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic meter per years?
Cubic Meter per Years (m3/yr) is a unit of flow rate.
What is a gallon per years?
Gallon per Years (gal/yr) is a unit of flow rate.
Is the cubic meter per years to gallon per years conversion exact?
Yes. Both cubic meter per years and gallon per years are defined by fixed standards rather than physical artifacts, so the factor of 264.1720524 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.
