How do I use the cubic yard calculator?

Simply measure the length, width, and depth of your project area. Enter these dimensions into the calculator and select the unit of measurement you used (feet, inches, or yards). The tool will instantly convert your measurements and provide the total volume in cubic yards.

What is the formula for calculating cubic yards?

The standard formula is: (Length in feet × Width in feet × Depth in feet) ÷ 27 = Cubic Yards. Our calculator automates this process for you.

How many bags of concrete are in a cubic yard?

This depends on the bag size. For 80 lb. bags, you'll need approximately 45 bags to make one cubic yard. For 60 lb. bags, you'll need around 60 bags. Our dedicated Concrete Calculator can provide more precise estimates.

How do I calculate cubic yards for a cylinder (like a post hole)?

For a cylinder, the formula is (π × radius² × height) / 27, with all measurements in feet. While this main calculator is for rectangular areas, this formula can be used for manual calculations.

Should I add extra material to my order?

Yes, it is highly recommended to order 5-10% more material than calculated. This extra amount covers any potential for uneven ground, compaction of materials like soil and gravel, and minor spillage.

How many wheelbarrows are in a cubic yard?

A standard 2 cubic foot wheelbarrow will need about 13.5 full loads to move one cubic yard of material. A larger 3 cubic foot wheelbarrow will take 9 loads.

What's the difference between a cubic yard and a 'yard' of material?

In the context of materials like mulch, soil, or gravel, the terms are used interchangeably. When a supplier says a 'yard of topsoil,' they mean one cubic yard.

How deep should I make my mulch or topsoil?

For mulch, a depth of 3-4 inches is standard for suppressing weeds and retaining moisture. For new garden beds, a topsoil depth of 6-12 inches is common. For lawns, a thin layer of 1-2 inches is sufficient.

Can I mix units in the calculator?

Our calculator requires you to select one unit for all three dimensions to ensure accuracy. Please convert your measurements to a single unit (e.g., all in inches or all in feet) before entering them.

How much does a cubic yard of gravel weigh?

The weight varies by the type of rock, but a cubic yard of typical gravel weighs approximately 2,400 to 2,900 pounds (about 1.2 to 1.45 tons).

What is a Cubic Yard?

A cubic yard is a measure of volume equal to a cube with sides of one yard (3 feet) in length.

Key Conversion:

1 Cubic Yard = 27 Cubic Feet

(3 ft × 3 ft × 3 ft = 27 cubic feet)

The Cubic Yard Formula Explained

Basic Formula:

Volume (yd³) = (Length × Width × Depth) ÷ 27

All measurements must be in feet. The result is divided by 27 because there are 27 cubic feet in one cubic yard.

Example Calculation:

For a 10ft × 12ft × 0.33ft concrete slab:
(10 × 12 × 0.33) ÷ 27 = 1.47 cubic yards
