Circular Hole Volume Calculator

This Soil Volume Weight Swell Calculator calculates the volume of a post hole, the weight of soil removed, and the increased volume of soil removed factored for swell.

 

Soil Volume Weight Swell Calculators
6-Inch Diameter Hole 4-Feet Deep in Dry Clay = .79 cu ft, 78.54 lbs, 5.88 gallons.  Swell volume 1.03 cu ft, 7.68 gallons.

 

Removed Clay Soil Swell Factor
Dirt vacuumed out of a hole has a very fine consistency and increased volume

Soil Volume, Soil Weight, and Swell Calculator

Use the following Soil Volume Weight Swell Calculator to determine the volume of a 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.

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.

Selecting a Shop Vacuum

These numbers are useful 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.  Also see the blog page on Digging Deep, Straight, Uniform Holes with a Shop-Vac for more information.

Soil Volume Weight Swell 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 density and swell factor

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

Input – Hole Diameter and Hole Depth

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

Summary

This Soil Volume Weight Swell Calculator makes it easy to calculate the volume of a hole.  In addition, it calculates the weight and volume of soil removed from the hole. In addition, It is also a very useful tool when using a Holey-Moley Fence Post Hole Digger because you can determine the size of shop vacuum canister required to hold the removed soil.
