About Converting Cubic Kilometer per Seconds to Gallon per Hours
Cubic Kilometer per Seconds and Gallon per Hours 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 hours = cubic kilometer per seconds × 9.510194e+14
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic kilometer per seconds equals 1000000000 base units, and 1 gallon per hours equals 0.00000105150327333 base units, so dividing one by the other gives the direct cubic kilometer per seconds-to-gallon per hours factor of 9.510194e+14.
Simple example
1 km3/s × 9.510194e+14 = 9.510194e+14 gal/h
1 cubic kilometer per seconds = 9.510194e+14 gallon per hours.
Real-world example
60 km3/s × 9.510194e+14 = 5.706116e+16 gal/h
60 cubic kilometer per seconds = 5.706116e+16 gallon per hours.

Frequently asked questions
How many gallon per hours are in 1 cubic kilometer per seconds?
1 cubic kilometer per seconds equals 9.510194e+14 gallon per hours, using the exact defined conversion factor rather than an estimate.
How do I convert cubic kilometer per seconds to gallon per hours?
Multiply the cubic kilometer per seconds value by 9.510194e+14. The converter above does this instantly to whatever precision you set.
How do I convert gallon per hours back to cubic kilometer per seconds?
Use the reverse factor: 1 gallon per hours equals 1.051503e-15 cubic kilometer per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic kilometer per seconds?
Cubic Kilometer per Seconds (km3/s) is a unit of flow rate.
What is a gallon per hours?
Gallon per Hours (gal/h) is a unit of flow rate.
Is the cubic kilometer per seconds to gallon per hours conversion exact?
Yes. Both cubic kilometer per seconds and gallon per hours are defined by fixed standards rather than physical artifacts, so the factor of 9.510194e+14 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.
