About Converting Cubic feet per Millisecond to Quart per Days
Cubic foot per Millisecond and Quart per Days 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
quart per days = cubic feet per millisecond × 2585267532.47
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic foot per millisecond equals 28.316846592 base units, and 1 quart per days equals 1.095316e-8 base units, so dividing one by the other gives the direct cubic foot per millisecond-to-quart per days factor of 2585267532.47.
Simple example
1 ft3/ms × 2585267532 = 2,585,267,532 qt/d
1 cubic foot per millisecond = 2,585,267,532 quart per days.
Real-world example
60 ft3/ms × 2585267532 = 155,116,051,900 qt/d
60 cubic feet per millisecond = 155,116,051,900 quart per days.

Frequently asked questions
How many quart per days are in 1 cubic foot per millisecond?
1 cubic foot per millisecond equals 2,585,267,532 quart per days, using the exact defined conversion factor rather than an estimate.
How do I convert cubic foot per millisecond to quart per days?
Multiply the cubic foot per millisecond value by 2585267532. The converter above does this instantly to whatever precision you set.
How do I convert quart per days back to cubic foot per millisecond?
Use the reverse factor: 1 quart per days equals 3.868072e-10 cubic feet per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic foot per millisecond?
Cubic foot per Millisecond (ft3/ms) is a unit of flow rate.
What is a quart per days?
Quart per Days (qt/d) is a unit of flow rate.
Is the cubic foot per millisecond to quart per days conversion exact?
Yes. Both cubic foot per millisecond and quart per days are defined by fixed standards rather than physical artifacts, so the factor of 2585267532 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.
