This calculator helps you determine the total volume and number of bushels in a round grain bin. The calculation includes the volume in cubic feet and litres and the amount of bushels it can hold.

The United States uses the Winchester bushel (1.244456 ft²), and Canada uses the Avery bushel ( 1.284349 ft²).

Calculator

1. diameter of the bin in feet
2. height of the bin in feet

Results

1. bin volume in cubic feet
2. bin volume in litres
3. number of US (Winchester) bushels
4. number of Imperial (Avery) bushels

Volume Formula

V = Π (D/2)²H
where V is the volume of the bin
Π = 3.14159
D = the diameter of the bin
H = the height of the bin
