Feed Bin Capacity Calculator
Choose a cylindrical or rectangular hopper approximation, enter its dimensions and the feed density.
A QUICK WALKTHROUGH
How to use this tool
- Select the bin shape.
- Enter the dimensions for that shape and a positive feed density.
- Review geometric volume and estimated tonnes.
Formula and scope
Cylinder volume = π × (diameter ÷ 2)² × height. Rectangular hopper approximation = length × width × (straight-sided depth + hopper depth ÷ 3). Tonnes = volume × feed density ÷ 1,000.
Limitations
The hopper taper is approximated and actual usable capacity is lower due to headspace, bridging, rat-holing, and incomplete filling. Feed density varies; check the manufacturer rating where available.

GOOD TO KNOW
Common questions
What density should I use?
Enter a density from the feed supplier for the specific meal, pellet, or rolled cereal.
Is this the rated usable capacity?
No. It is a geometric fill estimate and may exceed the usable or discharged amount.
