About Converting Bushel per Days to Quart per Seconds
Bushel 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 = bushel per days × 0.000430980439314
This factor comes from each unit's defined relationship to the category's base unit: 1 bushel per days equals 4.078596e-7 base units, and 1 quart per seconds equals 0.000946352946 base units, so dividing one by the other gives the direct bushel per days-to-quart per seconds factor of 0.000430980439314.
Simple example
1 bu/d × 0.0004309804393 = 0.0004309804 qt/s
1 bushel per days = 0.0004309804 quart per seconds.
Real-world example
60 bu/d × 0.0004309804393 = 0.0258588264 qt/s
60 bushel per days = 0.0258588264 quart per seconds.

Frequently asked questions
How many quart per seconds are in 1 bushel per days?
1 bushel per days equals 0.0004309804 quart per seconds, using the exact defined conversion factor rather than an estimate.

Multiply the bushel per days value by 0.0004309804393. The converter above does this instantly to whatever precision you set.
How do I convert quart per seconds back to bushel per days?
Use the reverse factor: 1 quart per seconds equals 2,320.29092 bushel per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a bushel per days?
Bushel per Days (bu/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 bushel per days to quart per seconds conversion exact?
Yes. Both bushel per days and quart per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.0004309804393 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.
