Bin Capacity Calculator
Calculate grain bin storage capacity in cubic feet and bushels.
Inputs
How It Works
Cylinder Volume = π × r² × height
Peak Volume = (1/3) × π × r² × peak height
1 Bushel ≈ 1.244 cubic feet (corn)
FAQ
How many cubic feet are in a bushel?
One bushel equals approximately 1.244 cubic feet for corn.
Does grain type affect capacity?
Yes. Different grains have slightly different bulk densities, affecting true storage weight capacity.
Why include peak height?
Grain often forms a peak when filled, increasing total storage capacity beyond sidewall height.
About Grain Bin Capacity
Grain bin capacity is determined by the bin's diameter, sidewall height, and the height of the grain peak formed during filling. Most farm bins are cylindrical structures, making volume calculations straightforward using standard geometry formulas.
Understanding bin capacity helps producers plan harvest logistics, grain marketing, and storage strategy. Accurate capacity estimation ensures proper aeration planning, reduces spoilage risk, and prevents overfilling during peak harvest conditions.
While volume provides an estimate in bushels, actual weight capacity also depends on grain moisture and bulk density. Monitoring bin capacity alongside moisture and shrink calculations supports better storage management decisions.
