About Converting Gallon per Weeks to Cubic Meter per Years
Gallon per Weeks 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 weeks × 0.19751332336
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per weeks equals 6.258948e-9 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 weeks-to-cubic meter per years factor of 0.19751332336.
Simple example
1 gal/wk × 0.1975133234 = 0.1975133234 m3/yr
1 gallon per weeks = 0.1975133234 cubic meter per years.
Real-world example
60 gal/wk × 0.1975133234 = 11.8507994 m3/yr
60 gallon per weeks = 11.8507994 cubic meter per years.

Frequently asked questions
How many cubic meter per years are in 1 gallon per weeks?
1 gallon per weeks equals 0.1975133234 cubic meter per years, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per weeks to cubic meter per years?
Multiply the gallon per weeks value by 0.1975133234. The converter above does this instantly to whatever precision you set.
How do I convert cubic meter per years back to gallon per weeks?
Use the reverse factor: 1 cubic meter per years equals 5.062949592 gallon per weeks. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per weeks?
Gallon per Weeks (gal/wk) 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 weeks to cubic meter per years conversion exact?
Yes. Both gallon per weeks and cubic meter per years are defined by fixed standards rather than physical artifacts, so the factor of 0.1975133234 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.
