About Converting Cubic yard per Seconds to Quarts per Millisecond
Cubic yard per Seconds and Quart per Millisecond 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
quarts per millisecond = cubic yard per seconds × 0.807896103896
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 millisecond equals 0.946352946 base units, so dividing one by the other gives the direct cubic yard per seconds-to-quart per millisecond factor of 0.807896103896.
Simple example
1 yd3/s × 0.8078961039 = 0.8078961039 qt/ms
1 cubic yard per seconds = 0.8078961039 quarts per millisecond.
Real-world example
60 yd3/s × 0.8078961039 = 48.47376623 qt/ms
60 cubic yard per seconds = 48.47376623 quarts per millisecond.

Frequently asked questions
How many quarts per millisecond are in 1 cubic yard per seconds?
1 cubic yard per seconds equals 0.8078961039 quarts per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert cubic yard per seconds to quart per millisecond?
Multiply the cubic yard per seconds value by 0.8078961039. The converter above does this instantly to whatever precision you set.
How do I convert quart per millisecond back to cubic yard per seconds?
Use the reverse factor: 1 quart per millisecond equals 1.237782922 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 millisecond?
Quart per Millisecond (qt/ms) is a unit of flow rate.
Is the cubic yard per seconds to quart per millisecond conversion exact?
Yes. Both cubic yard per seconds and quart per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.8078961039 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.
