About Converting Cubic Kilometer per Weeks to Gallon per Days
Cubic Kilometer per Weeks and Gallon per Days 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 days = cubic kilometer per weeks × 37738864622.6
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic kilometer per weeks equals 1653.43915344 base units, and 1 gallon per days equals 4.381264e-8 base units, so dividing one by the other gives the direct cubic kilometer per weeks-to-gallon per days factor of 37738864622.6.
Simple example
1 km3/wk × 37738864620 = 37,738,864,620 gal/d
1 cubic kilometer per weeks = 37,738,864,620 gallon per days.
Real-world example
60 km3/wk × 37738864620 = 2.264332e+12 gal/d
60 cubic kilometer per weeks = 2.264332e+12 gallon per days.

Frequently asked questions
How many gallon per days are in 1 cubic kilometer per weeks?
1 cubic kilometer per weeks equals 37,738,864,620 gallon per days, using the exact defined conversion factor rather than an estimate.
How do I convert cubic kilometer per weeks to gallon per days?
Multiply the cubic kilometer per weeks value by 37738864620. The converter above does this instantly to whatever precision you set.
How do I convert gallon per days back to cubic kilometer per weeks?
Use the reverse factor: 1 gallon per days equals 2.649788e-11 cubic kilometer per weeks. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic kilometer per weeks?
Cubic Kilometer per Weeks (km3/wk) is a unit of flow rate.
What is a gallon per days?
Gallon per Days (gal/d) is a unit of flow rate.
Is the cubic kilometer per weeks to gallon per days conversion exact?
Yes. Both cubic kilometer per weeks and gallon per days are defined by fixed standards rather than physical artifacts, so the factor of 37738864620 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.
