About Converting Cup per Days to Quart per Days
Cup per Days 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 = cup per days × 0.25
This factor comes from each unit's defined relationship to the category's base unit: 1 cup per days equals 2.73829e-9 base units, and 1 quart per days equals 1.095316e-8 base units, so dividing one by the other gives the direct cup per days-to-quart per days factor of 0.25.
Simple example
1 cup/d × 0.25 = 0.25 qt/d
1 cup per days = 0.25 quart per days.
Real-world example
60 cup/d × 0.25 = 15 qt/d
60 cup per days = 15 quart per days.

Frequently asked questions
How many quart per days are in 1 cup per days?
1 cup per days equals 0.25 quart per days, using the exact defined conversion factor rather than an estimate.
How do I convert cup per days to quart per days?
Multiply the cup per days value by 0.25. The converter above does this instantly to whatever precision you set.
How do I convert quart per days back to cup per days?
Use the reverse factor: 1 quart per days equals 4 cup per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a cup per days?
Cup per Days (cup/d) 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 cup per days to quart per days conversion exact?
Yes. Both cup per days and quart per days are defined by fixed standards rather than physical artifacts, so the factor of 0.25 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.
