Bin Capacity Calculator

Bushel capacities are approximate.

Do not include:

reference to bushels on this page.

reference to feed bin capacity at 40lbs,

reference to steep cone bins and liquid bins

Feed bin capacities are based on 40 lbs/ft3.

All fertilizer bins, steep cone bins and liquid bins capacities are based on 62 lbs/ft3.

To select the most appropriate bin size for your storage, please follow these steps:

  • Determine product density (lbs/ft3).
  • Convert the total tonnage being stored to lbs, then divide by the density.
    • The result is the cubic foot capacity you require.
    • Ex. You need to store 100 MT of urea fertilizer with a density of 48 lbs.
      100 x 2204 = 220,400 / 48 = 4592 (Min. ft3 required)

To calculate a bins holding capacity of a specific product, follow these steps:

  • Determine product density (lbs/ft3).
  • Multiply the bins cubic foot capacity by the product density, then divide by 2204.

Ex. Your fertilizer blend weights 57 lbs/ft3 and your purchasing a model 1425 fertilizer bin. Model 1425 = 4065 ft3 x 57 lbs = 231,648 lbs / 2204 = 105 MT. Your new 1425 will hold approx. 105 MT of your specific fertilizer blend.
