How to Use This Calculator
  1. Enter bin diameter and eave height in feet.
  2. Set the grain type and packing factor.
  3. Review total bin capacity in bushels.
  4. Compare capacity to your expected harvest to plan additional storage needs.
  5. Use the capacity output for bin rental decisions and elevator scheduling.

What each input means

Bin Diameter
Inside diameter of the grain bin in feet.
Grain Depth (sidewall)
Depth of grain at the sidewall in feet (not total bin height).
Grain Type
Select grain: 1 = Corn (56 lb/bu), 2 = Soybean (60 lb/bu), 3 = Wheat (60 lb/bu), 4 = Oats (32 lb/bu).
Peak Angle
Angle of the grain peak above the sidewall level in degrees. Set to 0 if grain is leveled.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Bin Diameter = 36, Grain Depth (sidewall) = 24, Grain Type = 1, Peak Angle = 15 = 4 input(s) provided
  2. Calculate Bin Capacity
    Bin Capacity
    20945 = 20945
  3. Calculate Total Weight
    Total Weight
    586.4 = 586.4
  4. Calculate Total Weight
    Total Weight
    1172893 = 1172893
