About Converting Cubic foot per Days to Quart per Seconds
Cubic foot per Days and Quart 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
quart per seconds = cubic foot per days × 0.00034632034632
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic foot per days equals 3.277413e-7 base units, and 1 quart per seconds equals 0.000946352946 base units, so dividing one by the other gives the direct cubic foot per days-to-quart per seconds factor of 0.00034632034632.
Simple example
1 ft3/d × 0.0003463203463 = 0.0003463203 qt/s
1 cubic foot per days = 0.0003463203 quart per seconds.
Real-world example
60 ft3/d × 0.0003463203463 = 0.0207792208 qt/s
60 cubic foot per days = 0.0207792208 quart per seconds.

Frequently asked questions
How many quart per seconds are in 1 cubic foot per days?
1 cubic foot per days equals 0.0003463203 quart per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cubic foot per days to quart per seconds?
Multiply the cubic foot per days value by 0.0003463203463. The converter above does this instantly to whatever precision you set.
How do I convert quart per seconds back to cubic foot per days?
Use the reverse factor: 1 quart per seconds equals 2,887.5 cubic foot per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic foot per days?
Cubic foot per Days (ft3/d) is a unit of flow rate.
What is a quart per seconds?
Quart per Seconds (qt/s) is a unit of flow rate.
Is the cubic foot per days to quart per seconds conversion exact?
Yes. Both cubic foot per days and quart per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.0003463203463 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.
