This grain volume and bushel calculator is designed to estimate the amount of grain inside a round grain bin based on the bin's dimensions and the grain's height. The calculator provides results for both level and peaked grain, taking into account the natural angle of repose to calculate the volume of the grain peak. Additionally, it factors in the volume of the bin roof, assuming a slope of 30 degrees. The tool outputs volumes in cubic feet and conversions to US bushels (Winchester) and Imperial bushels (Avery), helping you understand how much grain is stored inside the bin.

Calculator

1. enter the diameter of the bin in feet
2. the height of the bin in feet
3. the height of the grain inside the bin
4. the angle of repose for the grain

Results

1. the volume of the roof section, assuming a slope of 30 degrees
2. the total volume of the bin in cubic feet (cylinder and sloped roof)
3. the amount of grain in cubic feet when the grain is level inside the bin
4. the volume of the grain peak that forms above the level grain (calculated using the angle of repose)
5. the total amount of grain, including both the level grain and the peak
6. number of US bushels inside the bin if the grain is level on top
7. number of US bushels if the grain has a peak
8. number of Imperial bushels inside the bin if the grain is level on top
9. number of Imperial bushels if the grain has a peak

This calculator helps users accurately estimate the amount of grain stored inside a bin, whether level or peaked, using multiple units like cubic feet, US bushels, and Imperial bushels.
