About Converting Quart per Hours to Cubic yard per Seconds
Quart per Hours 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 = quart per hours × 3.438286e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 quart per hours equals 2.628758e-7 base units, and 1 cubic yard per seconds equals 0.764554857984 base units, so dividing one by the other gives the direct quart per hours-to-cubic yard per seconds factor of 3.438286e-7.
Simple example
1 qt/h × 3.438286e-7 = 3.438286e-7 yd3/s
1 quart per hours = 3.438286e-7 cubic yard per seconds.
Real-world example
60 qt/h × 3.438286e-7 = 0.0000206297 yd3/s
60 quart per hours = 0.0000206297 cubic yard per seconds.

Frequently asked questions
How many cubic yard per seconds are in 1 quart per hours?
1 quart per hours equals 3.438286e-7 cubic yard per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert quart per hours to cubic yard per seconds?
Multiply the quart per hours value by 3.438286e-7. The converter above does this instantly to whatever precision you set.
How do I convert cubic yard per seconds back to quart per hours?
Use the reverse factor: 1 cubic yard per seconds equals 2,908,425.974 quart per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a quart per hours?
Quart per Hours (qt/h) 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 quart per hours to cubic yard per seconds conversion exact?
Yes. Both quart per hours and cubic yard per seconds are defined by fixed standards rather than physical artifacts, so the factor of 3.438286e-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.
