About Converting Gallon per Weeks to Cubic Kilometer per Years
Gallon per Weeks and Cubic Kilometer 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 kilometer per years = gallon per weeks × 1.975133e-10
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 kilometer per years equals 31.6887385068 base units, so dividing one by the other gives the direct gallon per weeks-to-cubic kilometer per years factor of 1.975133e-10.
Simple example
1 gal/wk × 1.975133e-10 = 1.975133e-10 km3/yr
1 gallon per weeks = 1.975133e-10 cubic kilometer per years.
Real-world example
60 gal/wk × 1.975133e-10 = 1.18508e-8 km3/yr
60 gallon per weeks = 1.18508e-8 cubic kilometer per years.

Frequently asked questions
How many cubic kilometer per years are in 1 gallon per weeks?
1 gallon per weeks equals 1.975133e-10 cubic kilometer per years, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per weeks to cubic kilometer per years?
Multiply the gallon per weeks value by 1.975133e-10. The converter above does this instantly to whatever precision you set.
How do I convert cubic kilometer per years back to gallon per weeks?
Use the reverse factor: 1 cubic kilometer per years equals 5,062,949,592 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 kilometer per years?
Cubic Kilometer per Years (km3/yr) is a unit of flow rate.
Is the gallon per weeks to cubic kilometer per years conversion exact?
Yes. Both gallon per weeks and cubic kilometer per years are defined by fixed standards rather than physical artifacts, so the factor of 1.975133e-10 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.
