Inventor of the Holey-Moley Digger

Use the following Circular Hole Soil Volume Weight Calculator to determine the volume of a round hole in (cubic feet) and (gallons), the weight of the soil removed and the new volume in (cubic feet) and (gallons) based on soil swell factor.  In addition, the calculated numbers can be used to determine the amount of soil that a Shop Vacuum will have to remove in Cubic Feet and Gallons and  Soil Weight in pounds.  Consequently, these numbers are especially relevant when selecting a shop vacuum as described in the blog article on Selecting The Best Hole Digging Shop Vacuum and for determining the size of a Shop Vacuum for digging holes.

Finally,  see the blog page on Digging Deep, Straight, Uniform Holes with a Shop-Vac for relevant information.  We love feedback, let us know how you like these calculators.  If you would like to be kept up-dated on blog articles please sign up for more information here.

Circular Hole Soil Volume Weight Calculator

This calculator outputs the hole volume in cubic feet and gallons, soil weight in pounds, based on selected soil densities and input hole dimensions. It also provides removed soil volume based on selected soil swell factors.

Input – Select Soil Type

1. Select Soil Type for Density

2. Select Soil Type (same as above) for Swell factor

Input – (diameter and depth – inches)

3. Input Hole Diameter in inches

4 Input Hole Depth in inches

Output (Volume)

1. Hole Volume – Cubic Feet

2. Hole Volume – Gallons

Output (Weight)

3. Soil Weight – Pounds

Output – Swell Volume (increased volume after removal from hole)

4. Soil Volume – Cubic Feet

5. Soil Volume – Gallons


This Soil Volume Weight Swell Calculator makes it easy to calculate the volume of a hole, the weight and volume of soil removed from the hole, which can be helpful when using a Holey-Moley Fence Post Hole Digger and for determining the size of shop vacuum canister required to hold the removed soil.
