Converting a flat area measurement into a volume is necessary any time you need to order bulk materials like mulch, soil, gravel, or concrete for a project. Enter your square feet and depth/height (in inches or feet) into the Square Feet to Cubic Yards Calculator to get your result in cubic yards. Secondary outputs include the equivalent in cubic feet and an estimated weight in tons.

A cubic yard is a unit of volume measurement equal to 27 cubic feet (3 feet × 3 feet × 3 feet). It's commonly used in construction and landscaping to measure bulk materials like concrete, soil, mulch, and gravel.
To convert square feet to cubic yards, multiply your square footage by the depth in feet to get cubic feet, then divide by 27. For example: 100 sq ft × 0.25 ft depth = 25 cubic feet ÷ 27 = 0.93 cubic yards.
Yes, it's recommended to add 5-10% extra material to account for waste, compaction, and settling. This ensures you have enough material to complete your project without running short.
There are 27 cubic feet in one cubic yard. This is because a cubic yard measures 3 feet × 3 feet × 3 feet = 27 cubic feet.
Yes, this calculator is perfect for estimating concrete volume. Enter your slab area in square feet and the thickness in inches, and you'll get the cubic yards of concrete needed for your project.
Square yards measure area (length × width) while cubic yards measure volume (length × width × height). Square yards are 2-dimensional, cubic yards are 3-dimensional measurements that include depth or thickness.
Weight varies by material: concrete weighs about 2 tons per cubic yard, topsoil about 1.3 tons, sand about 1.5 tons, and mulch about 0.5 tons. Our calculator provides a general estimate of 1.5 tons per cubic yard.
