About Converting Cubic yard per Seconds to Quart per Days
Cubic yard per Seconds and Quart 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
quart per days = cubic yard per seconds × 69802223.3766
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 quart per days equals 1.095316e-8 base units, so dividing one by the other gives the direct cubic yard per seconds-to-quart per days factor of 69802223.3766.
Simple example
1 yd3/s × 69802223.38 = 69,802,223.38 qt/d
1 cubic yard per seconds = 69,802,223.38 quart per days.
Real-world example
60 yd3/s × 69802223.38 = 4,188,133,403 qt/d
60 cubic yard per seconds = 4,188,133,403 quart per days.

Frequently asked questions
How many quart per days are in 1 cubic yard per seconds?
1 cubic yard per seconds equals 69,802,223.38 quart per days, using the exact defined conversion factor rather than an estimate.
How do I convert cubic yard per seconds to quart per days?
Multiply the cubic yard per seconds value by 69802223.38. The converter above does this instantly to whatever precision you set.
How do I convert quart per days back to cubic yard per seconds?
Use the reverse factor: 1 quart per days equals 1.432619e-8 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 quart per days?
Quart per Days (qt/d) is a unit of flow rate.
Is the cubic yard per seconds to quart per days conversion exact?
Yes. Both cubic yard per seconds and quart per days are defined by fixed standards rather than physical artifacts, so the factor of 69802223.38 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.
