About Converting Cubic Kilometer per Years to Gallon per Years
Cubic Kilometer 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 kilometer per years × 264172052358
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic kilometer per years equals 31.6887385068 base units, and 1 gallon per years equals 1.199549e-10 base units, so dividing one by the other gives the direct cubic kilometer per years-to-gallon per years factor of 264172052358.
Simple example
1 km3/yr × 264172052400 = 264,172,052,400 gal/yr
1 cubic kilometer per years = 264,172,052,400 gallon per years.
Real-world example
60 km3/yr × 264172052400 = 1.585032e+13 gal/yr
60 cubic kilometer per years = 1.585032e+13 gallon per years.

Frequently asked questions
How many gallon per years are in 1 cubic kilometer per years?
1 cubic kilometer per years equals 264,172,052,400 gallon per years, using the exact defined conversion factor rather than an estimate.
How do I convert cubic kilometer per years to gallon per years?
Multiply the cubic kilometer per years value by 264172052400. The converter above does this instantly to whatever precision you set.
How do I convert gallon per years back to cubic kilometer per years?
Use the reverse factor: 1 gallon per years equals 3.785412e-12 cubic kilometer per years. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic kilometer per years?
Cubic Kilometer per Years (km3/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 kilometer per years to gallon per years conversion exact?
Yes. Both cubic kilometer per years and gallon per years are defined by fixed standards rather than physical artifacts, so the factor of 264172052400 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.
