About Converting Cubic feet per Millisecond to Cubic Kilometer per Hours
Cubic foot 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 = cubic feet per millisecond × 0.000101940647731
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic foot per millisecond equals 28.316846592 base units, and 1 cubic kilometer per hours equals 277777.777778 base units, so dividing one by the other gives the direct cubic foot per millisecond-to-cubic kilometer per hours factor of 0.000101940647731.
Simple example
1 ft3/ms × 0.0001019406477 = 0.0001019406 km3/h
1 cubic foot per millisecond = 0.0001019406 cubic kilometer per hours.
Real-world example
60 ft3/ms × 0.0001019406477 = 0.0061164389 km3/h
60 cubic feet per millisecond = 0.0061164389 cubic kilometer per hours.

Frequently asked questions
How many cubic kilometer per hours are in 1 cubic foot per millisecond?
1 cubic foot per millisecond equals 0.0001019406 cubic kilometer per hours, using the exact defined conversion factor rather than an estimate.
How do I convert cubic foot per millisecond to cubic kilometer per hours?
Multiply the cubic foot per millisecond value by 0.0001019406477. The converter above does this instantly to whatever precision you set.
How do I convert cubic kilometer per hours back to cubic foot per millisecond?
Use the reverse factor: 1 cubic kilometer per hours equals 9,809.629645 cubic feet per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic foot per millisecond?
Cubic foot per Millisecond (ft3/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 cubic foot per millisecond to cubic kilometer per hours conversion exact?
Yes. Both cubic foot per millisecond and cubic kilometer per hours are defined by fixed standards rather than physical artifacts, so the factor of 0.0001019406477 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.
