Gravel calculator Formula:

Width/3 x Length/3 x Depth/36

### Gravel calculator Definition

Our gravel calculator makes landscaping projects easier. When it comes to adding gravel, it is not enough to know the size of the area that needs to be covered. The depth of the gravel must also come into play. Problems arise for many people when they realize that they need to know how many cubic yards of gravel they need, but their measurements for the area was in feet and the depth was in inches.

Let our gravel needed calculator take the work out of helping you to determine the exact amount of gravel you need to purchase from the store. Our calculator converts your measurements into yards and gives you the answer you need in cubic yards, making your job of purchasing the gravel easier.

### Using the Calculator

When using our calculator you need to measure the following:

- Width of the site in feet
- Length of the site in feet
- Know the desired depth of the gravel in inches

### How Our Calculator Works

Our calculator takes each of the measurements you gave in feet and divides it by three to find how many yards are in the length and width measurements. The depth is converted to yards by dividing it by 36 because that is how many inches are in one yard.

To determine the area of a site in cubic yards, the converted measurements are multiplied together. Our calculator uses the formula to convert and calculate: width/3 x length/3 x depth/36 = amount of gravel in cubic yards.

Since our calculator takes the effort out of finding out how much gravel you need, you do not need to remember the formula or how to make the calculation manually. Just ensure that your measurements for the width and length are correct and in feet, and the depth desired for the gravel is in inches.

### How This Information Can Be Used

This calculator is helpful for finding the amount of gravel needed for a variety of projects. These may include:

When laying out the gravel in your landscape, whether for a walking path or garden, there are some tips to keep in mind:

- Measure the area accurately
