About Converting Gallons per Millisecond to Cubic Kilometer per Hours
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 = gallons per millisecond × 0.0000136274824224
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per millisecond equals 3.785411784 base units, and 1 cubic kilometer per hours equals 277777.777778 base units, so dividing one by the other gives the direct gallon per millisecond-to-cubic kilometer per hours factor of 0.0000136274824224.
Simple example
1 gal/ms × 0.00001362748242 = 0.0000136275 km3/h
1 gallon per millisecond = 0.0000136275 cubic kilometer per hours.
Real-world example
60 gal/ms × 0.00001362748242 = 0.0008176489 km3/h
60 gallons per millisecond = 0.0008176489 cubic kilometer per hours.

Frequently asked questions
How many cubic kilometer per hours are in 1 gallon per millisecond?
1 gallon per millisecond equals 0.0000136275 cubic kilometer per hours, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per millisecond to cubic kilometer per hours?
Multiply the gallon per millisecond value by 0.00001362748242. The converter above does this instantly to whatever precision you set.
How do I convert cubic kilometer per hours back to gallon per millisecond?
Use the reverse factor: 1 cubic kilometer per hours equals 73,381.12566 gallons per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per millisecond?
Gallon per Millisecond (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 gallon per millisecond to cubic kilometer per hours conversion exact?
Yes. Both gallon per millisecond and cubic kilometer per hours are defined by fixed standards rather than physical artifacts, so the factor of 0.00001362748242 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.
