Silo Volume Calculator

Step 1.

Measure around the barrel (circumference) of the silo and enter value. If you already know your silo's diameter from the manufacturer's specifications, change the option from the dropdown list to ‘diameter’ and enter this measurement instead.

Step 2.

Measure the barrel height to calculate the volume of the whole silo or, if it is not 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.

Step 3.

Finally, measure the height of the bottom cone of the silo. If you have an on-ground model, tick the box. Then click the "Calculate" button to show the results. You can change any of the measurements and hit the calculate button again to recalculate.

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