About Converting Bushel per Days to Quarts per Millisecond
Bushel per Days and Quart 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
quarts per millisecond = bushel per days × 4.309804e-7
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 millisecond equals 0.946352946 base units, so dividing one by the other gives the direct bushel per days-to-quart per millisecond factor of 4.309804e-7.
Simple example
1 bu/d × 4.309804e-7 = 4.309804e-7 qt/ms
1 bushel per days = 4.309804e-7 quarts per millisecond.
Real-world example
60 bu/d × 4.309804e-7 = 0.0000258588 qt/ms
60 bushel per days = 0.0000258588 quarts per millisecond.

Frequently asked questions
How many quarts per millisecond are in 1 bushel per days?
1 bushel per days equals 4.309804e-7 quarts per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert bushel per days to quart per millisecond?
Multiply the bushel per days value by 4.309804e-7. The converter above does this instantly to whatever precision you set.
How do I convert quart per millisecond back to bushel per days?
Use the reverse factor: 1 quart per millisecond equals 2,320,290.92 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 millisecond?
Quart per Millisecond (qt/ms) is a unit of flow rate.
Is the bushel per days to quart per millisecond conversion exact?
Yes. Both bushel per days and quart per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 4.309804e-7 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.
