About Converting Quart per Days to Cubic yards per Millisecond
Quart per Days and Cubic yard 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
cubic yards per millisecond = quart per days × 1.432619e-11
This factor comes from each unit's defined relationship to the category's base unit: 1 quart per days equals 1.095316e-8 base units, and 1 cubic yard per millisecond equals 764.554857984 base units, so dividing one by the other gives the direct quart per days-to-cubic yard per millisecond factor of 1.432619e-11.
Simple example
1 qt/d × 1.432619e-11 = 1.432619e-11 yd3/ms
1 quart per days = 1.432619e-11 cubic yards per millisecond.
Real-world example
60 qt/d × 1.432619e-11 = 8.595715e-10 yd3/ms
60 quart per days = 8.595715e-10 cubic yards per millisecond.

Frequently asked questions
How many cubic yards per millisecond are in 1 quart per days?
1 quart per days equals 1.432619e-11 cubic yards per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert quart per days to cubic yard per millisecond?
Multiply the quart per days value by 1.432619e-11. The converter above does this instantly to whatever precision you set.
How do I convert cubic yard per millisecond back to quart per days?
Use the reverse factor: 1 cubic yard per millisecond equals 69,802,223,380 quart per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a quart per days?
Quart per Days (qt/d) is a unit of flow rate.
What is a cubic yard per millisecond?
Cubic yard per Millisecond (yd3/ms) is a unit of flow rate.
Is the quart per days to cubic yard per millisecond conversion exact?
Yes. Both quart per days and cubic yard per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 1.432619e-11 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.
