About Converting Cubic Kilometer per Hours to Imperial gallon per Seconds
Cubic Kilometer per Hours and Imperial gallon per Seconds 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
imperial gallon per seconds = cubic kilometer per hours × 61102568.972
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic kilometer per hours equals 277777.777778 base units, and 1 imperial gallon per seconds equals 0.00454609 base units, so dividing one by the other gives the direct cubic kilometer per hours-to-imperial gallon per seconds factor of 61102568.972.
Simple example
1 km3/h × 61102568.97 = 61,102,568.97 imp gal/s
1 cubic kilometer per hours = 61,102,568.97 imperial gallon per seconds.
Real-world example
60 km3/h × 61102568.97 = 3,666,154,138 imp gal/s
60 cubic kilometer per hours = 3,666,154,138 imperial gallon per seconds.

Frequently asked questions
How many imperial gallon per seconds are in 1 cubic kilometer per hours?
1 cubic kilometer per hours equals 61,102,568.97 imperial gallon per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cubic kilometer per hours to imperial gallon per seconds?
Multiply the cubic kilometer per hours value by 61102568.97. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per seconds back to cubic kilometer per hours?
Use the reverse factor: 1 imperial gallon per seconds equals 1.636592e-8 cubic kilometer per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic kilometer per hours?
Cubic Kilometer per Hours (km3/h) is a unit of flow rate.
What is a imperial gallon per seconds?
Imperial gallon per Seconds (imp gal/s) is a unit of flow rate.
Is the cubic kilometer per hours to imperial gallon per seconds conversion exact?
Yes. Both cubic kilometer per hours and imperial gallon per seconds are defined by fixed standards rather than physical artifacts, so the factor of 61102568.97 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.
