Calculate Cubic Yards For Your Project

What is a cubic yard?

Before diving into the calculation, it's important to understand what a cubic yard is. A cubic yard is a unit of volume that is commonly used in construction and landscaping. It is equal to 27 cubic feet or approximately 764.6 liters. This measurement is often used to determine the amount of material needed for a project, such as soil, gravel, or concrete.

Calculating cubic yards for a square foot calculation

When you have a square foot calculation and you want to determine the amount of material needed in cubic yards, you can follow a simple formula:

Cubic Yards = Square Foot Calculation × Depth ÷ 27

Let's break down the formula:

  • Square Foot Calculation: This refers to the area you want to fill with material. For example, if you have a garden bed that measures 10 feet by 10 feet, your square foot calculation would be 100 square feet.
  • Depth: The depth is the thickness or height of the material you want to fill. It is typically measured in inches. For example, if you want to fill the garden bed with 6 inches of soil, your depth would be 6 inches.
  • 27: This number is used to convert cubic feet to cubic yards. Since there are 27 cubic feet in a cubic yard, dividing the total volume in cubic feet by 27 will give you the volume in cubic yards.

An example calculation

Let's say you have a patio that measures 15 feet by 20 feet, and you want to fill it with 4 inches of gravel. Here's how you would calculate the amount of material needed:

Square Foot Calculation = 15 feet × 20 feet = 300 square feet

Depth = 4 inches

Cubic Yards = 300 square feet × 4 inches ÷ 27 = 44.44 cubic yards

So, you would need approximately 44.44 cubic yards of gravel to fill your patio.


Calculating the amount of material in cubic yards for a square foot calculation is a straightforward process. By using the formula Square Foot Calculation × Depth ÷ 27, you can determine the volume of material needed for your project. Whether you're working on a construction site or planning a landscaping project, understanding how to calculate cubic yards can help you estimate the amount of material required and ensure a successful outcome.
