Enter the radius and height of a grain bin into the calculator to determine the grain bin capacity.

Grain Bin Capacity Formula

The following formula is used to calculate the capacity of a grain bin.

C = pi*r^2 * H

  • Where C is the the capacity (ft^3)
  • r is the radius of the bin (ft)
  • H is the height of the bin (ft)

This formula gives you the capacity in cubic feet. To convert into bushels, divide the results by 1.24446.

C = Volume (Ft^3) / 1.24446

What is a grain bin capacity?

Definition:

Grain bin capacity is defined as the total volume contained within a cylinder that is used for storing grain.

Most often grain bin capacity is measured in cubic feet or bushels.

How to claculate grain bin capacity?

Example Problem:

The following example problem outlines how to calculate the capacity of a grain bin.

First, determine the radius of the bin. In this example, the radius of the bin is measured to be 10 feet.

Next, determine the height of the bin. In this case, the height of the bin is measured to be 20 feet.

Finally, calculate the grain bin capacity using the formula above:

C = pi*r^2 * H

C = 3.14159*10^2 * 20

C = 6283.18 ft^3

To convert to bushels, divide the result by 1.24446.

C = 6283.18 / 1.24446 = 5048.92
