About Converting Cubic yard per Seconds to Cubic Kilometer per Days
Cubic yard per Seconds and Cubic Kilometer per Days 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 days = cubic yard per seconds × 0.0000660575397298
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic yard per seconds equals 0.764554857984 base units, and 1 cubic kilometer per days equals 11574.0740741 base units, so dividing one by the other gives the direct cubic yard per seconds-to-cubic kilometer per days factor of 0.0000660575397298.
Simple example
1 yd3/s × 0.00006605753973 = 0.0000660575 km3/d
1 cubic yard per seconds = 0.0000660575 cubic kilometer per days.
Real-world example
60 yd3/s × 0.00006605753973 = 0.0039634524 km3/d
60 cubic yard per seconds = 0.0039634524 cubic kilometer per days.

Frequently asked questions
How many cubic kilometer per days are in 1 cubic yard per seconds?
1 cubic yard per seconds equals 0.0000660575 cubic kilometer per days, using the exact defined conversion factor rather than an estimate.
How do I convert cubic yard per seconds to cubic kilometer per days?
Multiply the cubic yard per seconds value by 0.00006605753973. The converter above does this instantly to whatever precision you set.
How do I convert cubic kilometer per days back to cubic yard per seconds?
Use the reverse factor: 1 cubic kilometer per days equals 15,138.31735 cubic yard per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic yard per seconds?
Cubic yard per Seconds (yd3/s) is a unit of flow rate.
What is a cubic kilometer per days?
Cubic Kilometer per Days (km3/d) is a unit of flow rate.
Is the cubic yard per seconds to cubic kilometer per days conversion exact?
Yes. Both cubic yard per seconds and cubic kilometer per days are defined by fixed standards rather than physical artifacts, so the factor of 0.00006605753973 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.
