About Converting Imperial gallons per Millisecond to Cubic Kilometer per Hours
Imperial gallon per Millisecond and Cubic Kilometer 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
cubic kilometer per hours = imperial gallons per millisecond × 0.000016365924
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial gallon per millisecond equals 4.54609 base units, and 1 cubic kilometer per hours equals 277777.777778 base units, so dividing one by the other gives the direct imperial gallon per millisecond-to-cubic kilometer per hours factor of 0.000016365924.
Simple example
1 imp gal/ms × 0.000016365924 = 0.0000163659 km3/h
1 imperial gallon per millisecond = 0.0000163659 cubic kilometer per hours.
Real-world example
60 imp gal/ms × 0.000016365924 = 0.0009819554 km3/h
60 imperial gallons per millisecond = 0.0009819554 cubic kilometer per hours.

Frequently asked questions
How many cubic kilometer per hours are in 1 imperial gallon per millisecond?
1 imperial gallon per millisecond equals 0.0000163659 cubic kilometer per hours, using the exact defined conversion factor rather than an estimate.
How do I convert imperial gallon per millisecond to cubic kilometer per hours?
Multiply the imperial gallon per millisecond value by 0.000016365924. The converter above does this instantly to whatever precision you set.
How do I convert cubic kilometer per hours back to imperial gallon per millisecond?
Use the reverse factor: 1 cubic kilometer per hours equals 61,102.56897 imperial gallons per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial gallon per millisecond?
Imperial gallon per Millisecond (imp gal/ms) is a unit of flow rate.
What is a cubic kilometer per hours?
Cubic Kilometer per Hours (km3/h) is a unit of flow rate.
Is the imperial gallon per millisecond to cubic kilometer per hours conversion exact?
Yes. Both imperial gallon per millisecond and cubic kilometer per hours are defined by fixed standards rather than physical artifacts, so the factor of 0.000016365924 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.
