Formula
- Use the units shown beside each field.
- Results update automatically whenever you change an input.
- Displayed values use up to four decimal places, or scientific notation for very small or large numbers. Calculations use standard floating-point arithmetic; exact integer and fraction tools identify their own precision rules.
- Ideal cylindrical fill with a complete top cone. Compaction, aeration ducts, moisture and angle-of-repose variation are excluded.
Example Calculation
- Bin diameter: 6 m
- Filled cylinder height: 4 m
- Top cone height: 1 m
- Bulk density: 750 kg/m³
Bin diameter = 6; Filled cylinder height = 4; Top cone height = 1; Bulk density = 750. Primary result: 122.52211349.
Frequently asked questions
How do I use this calculator?
Enter bin diameter, filled cylinder height, top cone height, bulk density. The result updates automatically. Use Reset to restore the example values.
What method does it use?
V=πr²h+πr²cone height/3; mass=V ×bulk density.. Ideal cylindrical fill with a complete top cone. Compaction, aeration ducts, moisture and angle-of-repose variation are excluded.
Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
Are my inputs saved online?
No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
