About Converting Gallon per Weeks to Cubic Millimeter per Years
Gallon per Weeks and Cubic Millimeter 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 millimeter per years = gallon per weeks × 197513323.36
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 millimeter per years equals 3.168874e-17 base units, so dividing one by the other gives the direct gallon per weeks-to-cubic millimeter per years factor of 197513323.36.
Simple example
1 gal/wk × 197513323.4 = 197,513,323.4 mm3/yr
1 gallon per weeks = 197,513,323.4 cubic millimeter per years.
Real-world example
60 gal/wk × 197513323.4 = 11,850,799,400 mm3/yr
60 gallon per weeks = 11,850,799,400 cubic millimeter per years.

Frequently asked questions
How many cubic millimeter per years are in 1 gallon per weeks?
1 gallon per weeks equals 197,513,323.4 cubic millimeter per years, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per weeks to cubic millimeter per years?
Multiply the gallon per weeks value by 197513323.4. The converter above does this instantly to whatever precision you set.
How do I convert cubic millimeter per years back to gallon per weeks?
Use the reverse factor: 1 cubic millimeter per years equals 5.06295e-9 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 millimeter per years?
Cubic Millimeter per Years (mm3/yr) is a unit of flow rate.
Is the gallon per weeks to cubic millimeter per years conversion exact?
Yes. Both gallon per weeks and cubic millimeter per years are defined by fixed standards rather than physical artifacts, so the factor of 197513323.4 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.
