About Converting Quarts per Millisecond to Cubic yard per Seconds
Quart per Millisecond 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 = quarts per millisecond × 1.23778292181
This factor comes from each unit's defined relationship to the category's base unit: 1 quart per millisecond equals 0.946352946 base units, and 1 cubic yard per seconds equals 0.764554857984 base units, so dividing one by the other gives the direct quart per millisecond-to-cubic yard per seconds factor of 1.23778292181.
Simple example
1 qt/ms × 1.237782922 = 1.237782922 yd3/s
1 quart per millisecond = 1.237782922 cubic yard per seconds.
Real-world example
60 qt/ms × 1.237782922 = 74.26697531 yd3/s
60 quarts per millisecond = 74.26697531 cubic yard per seconds.

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