About Converting Cubic Millimeter per Years to Gallon per Weeks
Cubic Millimeter per Years and Gallon per Weeks 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 weeks = cubic millimeter per years × 5.06295e-9
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic millimeter per years equals 3.168874e-17 base units, and 1 gallon per weeks equals 6.258948e-9 base units, so dividing one by the other gives the direct cubic millimeter per years-to-gallon per weeks factor of 5.06295e-9.
Simple example
1 mm3/yr × 5.06295e-9 = 5.06295e-9 gal/wk
1 cubic millimeter per years = 5.06295e-9 gallon per weeks.
Real-world example
60 mm3/yr × 5.06295e-9 = 3.03777e-7 gal/wk
60 cubic millimeter per years = 3.03777e-7 gallon per weeks.

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