**The following Holey-Moley Tools consist of different calculators to help with tasks relating to soils, such as the weight and volume of soil removed from circular and rectangular holes including the swell volumes.**

## Holey-Moley Tools – Soil & Hole Calculators

The following calculators are accessible via the hyperlink. Further description supplied in the numbered descriptions below and can also be found on the calculator pages.

**1. Circular Holes – Soil Volume, Weight, Swell calculator**

**2. Rectangular Holes – Soil Volume, Weight Swell, calculator**

**3. PVC Pipe Volume, & Water Weight, Calculator**

##### 4. **4×4 Fence Post Hole Concrete Calculator**

##### 5. PVC Constant Volume Pipe Length Calculator

### 1. Circular Hole

**Circular Holes – Soil Volume, Weight Swell, Calculator**

Use the following Holey-Moley Tools – * 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.

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. We love feedback, let us know how you like these calculators.

#### Soil Volume Weight Swell Calculator

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

### 2. Rectangular Hole

**Rectangular Holes – Soil Volume Weight Swell calculator**

Use the following Holey-Moley Tools – * Rectangular Hole Soil Volume Calculator *to determine the volume of a rectangular hole, in (cubic feet), and in (gallons). The calculator also outputs the weight of the soil removed and the new volume, in (cubic feet), and in (gallons), based on the soil swell factor. The output numbers can be used to determine the amount of soil that a Shop Vacuum will have to remove in Cubic Feet, and in Gallons, and the Soil Weight in pounds.

These numbers will be 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. See the blog page article on Digging Deep, Straight, Uniform Holes with a Shop-Vac for more information.

#### Soil Volume Weight Swell Calculator

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

### 3. PVC Pipe Water Volume & Weight Calculator

**PVC Pipe Volume & Water Weight Calculator**

This calculator computes the volume of a cylinder pipe in gallons and the weight of water that this volume would hold when full. This calculator was developed for PVC “Cache” Storage tubes. The tubes can be filled with water for emergency purposes. The pipe size is selectable and the pipe length is a required input.

### 4. 4×4 Fence Post Hole Concrete Calculator

**4×4 Fence Post Hole Concrete Calculator**

This 4×4 Fence Post Hole Concrete Calculator computes the volume and weight of QUIKRETE required for a 4×4 post. Input hole diameter, hole depth and the number of post holes. The output also computes the total amount of QUIKRETE required and number of 40 pound, 60 pound, or 80 pound bags. For more information visit the QUICKRETE web page.

### 5. PVC Constant Volume Pipe Length Calculator

##### PVC Constant Volume Pipe Length Calculator

Use the following * Constant Volume Pipe Length Calculator *to determine the length of different diameters of standard PVC pipe for the same internal volume. The output is in (inches) for different standard diameters of SDR 35 and SDR 26 PVC Pipe. In addition, the standard internal diameters (ID’s) shown are for 4-inch, 6-inch, 8-inch, 10-inch and 12-inch PVC Pipe.
