About Converting Cubic yard per Seconds to Cubic Millimeter per Days
Cubic yard per Seconds and Cubic Millimeter 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 millimeter per days = cubic yard per seconds × 6.605754e+13
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 millimeter per days equals 1.157407e-14 base units, so dividing one by the other gives the direct cubic yard per seconds-to-cubic millimeter per days factor of 6.605754e+13.
Simple example
1 yd3/s × 6.605754e+13 = 6.605754e+13 mm3/d
1 cubic yard per seconds = 6.605754e+13 cubic millimeter per days.
Real-world example
60 yd3/s × 6.605754e+13 = 3.963452e+15 mm3/d
60 cubic yard per seconds = 3.963452e+15 cubic millimeter per days.

Frequently asked questions
How many cubic millimeter per days are in 1 cubic yard per seconds?
1 cubic yard per seconds equals 6.605754e+13 cubic millimeter per days, using the exact defined conversion factor rather than an estimate.
How do I convert cubic yard per seconds to cubic millimeter per days?
Multiply the cubic yard per seconds value by 6.605754e+13. The converter above does this instantly to whatever precision you set.
How do I convert cubic millimeter per days back to cubic yard per seconds?
Use the reverse factor: 1 cubic millimeter per days equals 1.513832e-14 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 millimeter per days?
Cubic Millimeter per Days (mm3/d) is a unit of flow rate.
Is the cubic yard per seconds to cubic millimeter per days conversion exact?
Yes. Both cubic yard per seconds and cubic millimeter per days are defined by fixed standards rather than physical artifacts, so the factor of 6.605754e+13 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.
