Silo Calculator

Instructions for Use of Silo Volume Calculator

For reasonable accuracy make all measurements to the nearest centimetre (0.01 of a metre) then enter them into the calculator in metres (eg. -if you measure 1052cm then enter 10.52m). Adhesive tape is useful for holding the end of the tape measure in the right spot when making measurements.

  • Measure around the barrel (circumference) of the silo and enter this into the first space. If you already know your silo’s diameter from the manufacturer’s specifications, click on Silo diameter and enter this measurement instead.
  • Measure the barrel height to calculate the volume of the whole silo or, if it isn’t full, the height of the contents against the silo wall to calculate the volume and weight of the contents. If the silo is being emptied (i.e. the top of the material is coned down) then tick the box.
  • Finally, measure the height of the bottom cone of the silo. Just leave this blank if the silo is an on-ground model. Then click the “Calculate” button to show the results. You can change any of the measurements and hit the calculate button again to recalculate.

Please note: The results from this calculator use standard material weights and are intended as a guide only. Actual material weights depend on many factors such as moisture content, grain size etc.
