About Converting Cubic yards per Millisecond to Cubic Kilometer per Seconds
Cubic yard per Millisecond and Cubic Kilometer 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
cubic kilometer per seconds = cubic yards per millisecond × 7.645549e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic yard per millisecond equals 764.554857984 base units, and 1 cubic kilometer per seconds equals 1000000000 base units, so dividing one by the other gives the direct cubic yard per millisecond-to-cubic kilometer per seconds factor of 7.645549e-7.
Simple example
1 yd3/ms × 7.645549e-7 = 7.645549e-7 km3/s
1 cubic yard per millisecond = 7.645549e-7 cubic kilometer per seconds.
Real-world example
60 yd3/ms × 7.645549e-7 = 0.0000458733 km3/s
60 cubic yards per millisecond = 0.0000458733 cubic kilometer per seconds.

Frequently asked questions
How many cubic kilometer per seconds are in 1 cubic yard per millisecond?
1 cubic yard per millisecond equals 7.645549e-7 cubic kilometer per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cubic yard per millisecond to cubic kilometer per seconds?
Multiply the cubic yard per millisecond value by 7.645549e-7. The converter above does this instantly to whatever precision you set.
How do I convert cubic kilometer per seconds back to cubic yard per millisecond?
Use the reverse factor: 1 cubic kilometer per seconds equals 1,307,950.619 cubic yards per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic yard per millisecond?
Cubic yard per Millisecond (yd3/ms) is a unit of flow rate.
What is a cubic kilometer per seconds?
Cubic Kilometer per Seconds (km3/s) is a unit of flow rate.
Is the cubic yard per millisecond to cubic kilometer per seconds conversion exact?
Yes. Both cubic yard per millisecond and cubic kilometer per seconds are defined by fixed standards rather than physical artifacts, so the factor of 7.645549e-7 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.
