About Converting Cubic yard per Seconds to Imperial quarts per Millisecond
Cubic yard per Seconds and Imperial 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
imperial quarts per millisecond = cubic yard per seconds × 0.672714229577
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 imperial quart per millisecond equals 1.1365225 base units, so dividing one by the other gives the direct cubic yard per seconds-to-imperial quart per millisecond factor of 0.672714229577.
Simple example
1 yd3/s × 0.6727142296 = 0.6727142296 imp qt/ms
1 cubic yard per seconds = 0.6727142296 imperial quarts per millisecond.
Real-world example
60 yd3/s × 0.6727142296 = 40.36285377 imp qt/ms
60 cubic yard per seconds = 40.36285377 imperial quarts per millisecond.

Frequently asked questions
How many imperial quarts per millisecond are in 1 cubic yard per seconds?
1 cubic yard per seconds equals 0.6727142296 imperial quarts per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert cubic yard per seconds to imperial quart per millisecond?
Multiply the cubic yard per seconds value by 0.6727142296. The converter above does this instantly to whatever precision you set.
How do I convert imperial quart per millisecond back to cubic yard per seconds?
Use the reverse factor: 1 imperial quart per millisecond equals 1.486515308 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 imperial quart per millisecond?
Imperial quart per Millisecond (imp qt/ms) is a unit of flow rate.
Is the cubic yard per seconds to imperial quart per millisecond conversion exact?
Yes. Both cubic yard per seconds and imperial quart per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.6727142296 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.
