About Converting Cubic Kilometer per Hours to Cubic yards per Millisecond
Cubic Kilometer per Hours and Cubic yard per Millisecond 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 yards per millisecond = cubic kilometer per hours × 363.319616476
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 cubic yard per millisecond equals 764.554857984 base units, so dividing one by the other gives the direct cubic kilometer per hours-to-cubic yard per millisecond factor of 363.319616476.
Simple example
1 km3/h × 363.3196165 = 363.3196165 yd3/ms
1 cubic kilometer per hours = 363.3196165 cubic yards per millisecond.
Real-world example
60 km3/h × 363.3196165 = 21,799.17699 yd3/ms
60 cubic kilometer per hours = 21,799.17699 cubic yards per millisecond.

Frequently asked questions
How many cubic yards per millisecond are in 1 cubic kilometer per hours?
1 cubic kilometer per hours equals 363.3196165 cubic yards per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert cubic kilometer per hours to cubic yard per millisecond?
Multiply the cubic kilometer per hours value by 363.3196165. The converter above does this instantly to whatever precision you set.
How do I convert cubic yard per millisecond back to cubic kilometer per hours?
Use the reverse factor: 1 cubic yard per millisecond equals 0.0027523975 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 cubic yard per millisecond?
Cubic yard per Millisecond (yd3/ms) is a unit of flow rate.
Is the cubic kilometer per hours to cubic yard per millisecond conversion exact?
Yes. Both cubic kilometer per hours and cubic yard per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 363.3196165 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.
