About Converting Bushel per Days to Cubic Kilometer per Seconds
Bushel per Days and Cubic Kilometer 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
cubic kilometer per seconds = bushel per days × 4.078596e-16
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 cubic kilometer per seconds equals 1000000000 base units, so dividing one by the other gives the direct bushel per days-to-cubic kilometer per seconds factor of 4.078596e-16.
Simple example
1 bu/d × 4.078596e-16 = 4.078596e-16 km3/s
1 bushel per days = 4.078596e-16 cubic kilometer per seconds.
Real-world example
60 bu/d × 4.078596e-16 = 2.447158e-14 km3/s
60 bushel per days = 2.447158e-14 cubic kilometer per seconds.

Frequently asked questions
How many cubic kilometer per seconds are in 1 bushel per days?
1 bushel per days equals 4.078596e-16 cubic kilometer per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert bushel per days to cubic kilometer per seconds?
Multiply the bushel per days value by 4.078596e-16. The converter above does this instantly to whatever precision you set.
How do I convert cubic kilometer per seconds back to bushel per days?
Use the reverse factor: 1 cubic kilometer per seconds equals 2.451824e+15 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 cubic kilometer per seconds?
Cubic Kilometer per Seconds (km3/s) is a unit of flow rate.
Is the bushel per days to cubic kilometer per seconds conversion exact?
Yes. Both bushel per days and cubic kilometer per seconds are defined by fixed standards rather than physical artifacts, so the factor of 4.078596e-16 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.
