How do I calculate cubic yards of dirt?

Answered by Ricardo McCardle

Calculating cubic yards of dirt can be a straightforward process if you follow a few simple steps. Whether you’re planning a landscaping project or need to fill a space with dirt, knowing the amount of cubic yards required is essential. Let’s break down the steps to calculate cubic yards of dirt.

Step 1: Measure the Length, Width, and Depth
To begin, measure the length, width, and depth of the area where you plan to place the dirt. Make sure to measure in feet for consistency. For example, let’s say you’re working with a flower bed that is 10 feet long, 5 feet wide, and you need to add dirt that is 6 inches deep.

Step 2: Convert Inches to Feet
Next, convert the depth measurement from inches to feet. Since there are 12 inches in a foot, divide the depth measurement by 12. In our example, 6 inches divided by 12 equals 0.5 feet.

Step 3: Calculate the Volume
To determine the volume of the area in cubic feet, multiply the length, width, and depth measurements. In our example, 10 feet (length) multiplied by 5 feet (width) multiplied by 0.5 feet (depth) equals 25 cubic feet.

Step 4: Convert Cubic Feet to Cubic Yards
Since most suppliers sell dirt by the cubic yard, you’ll need to convert the cubic feet measurement to cubic yards. There are 27 cubic feet in a cubic yard, so divide the cubic feet by 27. In our example, 25 cubic feet divided by 27 equals approximately 0.93 cubic yards.

It’s important to note that this calculation provides an estimate and may not account for variations in dirt density or compaction. It’s always a good idea to add a little extra to your estimate to ensure you have enough dirt for your project.

To summarize the steps:
1. Measure the length, width, and depth in feet.
2. Convert the depth from inches to feet by dividing by 12.
3. Calculate the volume by multiplying the length, width, and depth.
4. Convert the volume from cubic feet to cubic yards by dividing by 27.

In my personal experience, I recently had to calculate the cubic yards of dirt for a backyard landscaping project. The area was irregularly shaped, so I had to break it down into smaller sections and calculate the volume for each section separately. I then added up the individual volumes to get the total cubic yards required. It was a bit time-consuming but ultimately gave me an accurate estimate for ordering the right amount of dirt.

Remember, it’s always better to have a little extra dirt than to run out in the middle of your project. Plus, having some extra dirt can come in handy for future gardening or landscaping needs.
