About Converting Gallon per Seconds to Cubic Kilometer per Days
Gallon per Seconds and Cubic Kilometer 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
cubic kilometer per days = gallon per seconds × 3.270596e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per seconds equals 0.003785411784 base units, and 1 cubic kilometer per days equals 11574.0740741 base units, so dividing one by the other gives the direct gallon per seconds-to-cubic kilometer per days factor of 3.270596e-7.
Simple example
1 gal/s × 3.270596e-7 = 3.270596e-7 km3/d
1 gallon per seconds = 3.270596e-7 cubic kilometer per days.
Real-world example
60 gal/s × 3.270596e-7 = 0.0000196236 km3/d
60 gallon per seconds = 0.0000196236 cubic kilometer per days.

Frequently asked questions
How many cubic kilometer per days are in 1 gallon per seconds?
1 gallon per seconds equals 3.270596e-7 cubic kilometer per days, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per seconds to cubic kilometer per days?
Multiply the gallon per seconds value by 3.270596e-7. The converter above does this instantly to whatever precision you set.
How do I convert cubic kilometer per days back to gallon per seconds?
Use the reverse factor: 1 cubic kilometer per days equals 3,057,546.902 gallon per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per seconds?
Gallon per Seconds (gal/s) is a unit of flow rate.
What is a cubic kilometer per days?
Cubic Kilometer per Days (km3/d) is a unit of flow rate.
Is the gallon per seconds to cubic kilometer per days conversion exact?
Yes. Both gallon per seconds and cubic kilometer per days are defined by fixed standards rather than physical artifacts, so the factor of 3.270596e-7 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.
