About Converting Imperial quart per Days to Cubic yard per Seconds
Imperial quart per Days and Cubic yard 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 yard per seconds = imperial quart per days × 1.720504e-8
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial quart per days equals 1.31542e-8 base units, and 1 cubic yard per seconds equals 0.764554857984 base units, so dividing one by the other gives the direct imperial quart per days-to-cubic yard per seconds factor of 1.720504e-8.
Simple example
1 imp qt/d × 1.720504e-8 = 1.720504e-8 yd3/s
1 imperial quart per days = 1.720504e-8 cubic yard per seconds.
Real-world example
60 imp qt/d × 1.720504e-8 = 0.0000010323 yd3/s
60 imperial quart per days = 0.0000010323 cubic yard per seconds.

Frequently asked questions
How many cubic yard per seconds are in 1 imperial quart per days?
1 imperial quart per days equals 1.720504e-8 cubic yard per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert imperial quart per days to cubic yard per seconds?
Multiply the imperial quart per days value by 1.720504e-8. The converter above does this instantly to whatever precision you set.
How do I convert cubic yard per seconds back to imperial quart per days?
Use the reverse factor: 1 cubic yard per seconds equals 58,122,509.44 imperial quart per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial quart per days?
Imperial quart per Days (imp qt/d) is a unit of flow rate.
What is a cubic yard per seconds?
Cubic yard per Seconds (yd3/s) is a unit of flow rate.
Is the imperial quart per days to cubic yard per seconds conversion exact?
Yes. Both imperial quart per days and cubic yard per seconds are defined by fixed standards rather than physical artifacts, so the factor of 1.720504e-8 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.
