This calculator computes volume for a round post hole in cubic feet and gallons and the weight and volume of soil removed.
Round Post Hole Calculator
Inventor of the Holey-Moley Digger
Use the following Calculator to determine the volume of a round post 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.
The Soil Volume Weight Calculator Inputs
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
Soil Volume Weight Calculator Outputs
1. Hole Volume – Cubic Feet
2. Hole Volume – Gallons
3. Soil Weight – Pounds
Output – Swell Volume (increased volume after removal from hole)
4. Volume – Cubic Feet
5. Volume – Gallons
This Calculator makes it easy to determine the volume of a post hole and the weight of soil removed. The result can be helpful when using a Holey-Moley Fence Post Hole Digger and for determining the size of a shop vacuum canister to hold the removed soil.
