Calculate cubic yards from dimensions or convert between volume units

V = L × W × H
1 yd³ = 27 ft³ = 46,656 in³
1 yd³ = 0.764555 m³ = 764.555 L
1 yd³ = 201.974 US gallons
A cubic yard (yd³) is a unit of volume in the Imperial and US customary measurement systems. It represents the volume of a cube with edges that are exactly one yard (three feet) in length. One cubic yard equals 27 cubic feet, since a yard contains 3 feet and 3³ = 27.
Cubic yards are the standard unit for ordering bulk materials in construction and landscaping industries throughout the United States. Concrete, mulch, soil, gravel, sand, and other bulk materials are almost always sold and delivered by the cubic yard. This makes the cubic yard one of the most practical volume measurements for contractors, landscapers, and homeowners undertaking outdoor projects.
Understanding cubic yards is essential for accurately estimating material quantities and costs. A typical concrete truck holds 10 cubic yards. A standard wheelbarrow holds about 0.11 cubic yards (3 cubic feet). A pickup truck bed can carry roughly 2-3 cubic yards of loose material. Knowing these relationships helps with planning deliveries, scheduling work, and managing budgets for construction and landscaping projects.
Step 1: Choose your calculation mode. Select "From Dimensions" if you have the length, width, and height (or depth) of the area you need to fill. Select "Unit Conversion" if you already have a volume measurement and want to convert it to or from cubic yards.
Step 2 (Dimensions Mode): Select your measurement unit (feet is most common for US projects), then enter the length, width, and depth. For example, a garden bed that's 12 feet long, 4 feet wide, and needs 6 inches (0.5 feet) of mulch.
Step 3 (Conversion Mode): Select the unit you're converting from, then enter the value. This is useful when you know the volume in cubic feet or other units but need to order materials in cubic yards.
Technical Details: When entering depth for materials like mulch or concrete, convert inches to feet by dividing by 12 (e.g., 4 inches = 0.33 feet, 6 inches = 0.5 feet). Always add 5-10% extra when ordering to account for settling, compaction, and waste. Round up to the nearest half or whole cubic yard when placing orders, as suppliers typically don't deliver partial yards.
Scenario: A landscaper needs to order mulch for a client's flower bed. The area is 12 feet long, 12 feet wide, and requires a 4-inch layer of mulch (0.33 feet).
Volume Needed: 1.78 cubic yards
Order Amount: 2 cubic yards (rounded up for waste)
Cost: At $35 per cubic yard, total = $70
Weight: Approximately 1,600 lbs (mulch weighs ~800 lbs/yd³)
By calculating the exact cubic yards needed, the landscaper can order the right amount of mulch—enough to complete the job with a small buffer for settling, but not so much that it wastes the client's money or requires disposal of excess material.
There are exactly 27 cubic feet in one cubic yard, since 1 yard = 3 feet, and 3³ = 27. This is the most important conversion for construction and landscaping calculations.
Weight varies by material: mulch ~800 lbs/yd³, topsoil ~2,000 lbs/yd³, sand/gravel ~2,700 lbs/yd³, concrete ~4,000 lbs/yd³. Always check weight limits for your vehicle or trailer.
Divide inches by 12 to get feet. Common conversions: 3 inches = 0.25 ft, 4 inches = 0.33 ft, 6 inches = 0.5 ft, 12 inches = 1 ft. Always use feet for all three dimensions.
Yes, always order 5-10% extra to account for settling, compaction, irregular terrain, and measurement variations. It's better to have a small amount left over than to run short and pay for a second delivery.
A standard 3 cubic foot wheelbarrow holds 1/9 of a cubic yard, so one cubic yard = 9 wheelbarrow loads. A 6 cubic foot contractor wheelbarrow requires 4.5 trips per cubic yard.
A full-size pickup bed (8 ft) holds about 2.5-3 cubic yards of loose material. A mid-size truck (6 ft bed) holds 1.5-2 cubic yards. Check your payload capacity—weight is often the limiting factor.
Square yards (yd²) measure area (2D surface), while cubic yards (yd³) measure volume (3D space). You need depth/height to convert between them: yd³ = yd² × depth in yards.
As of 2024, ready-mix concrete typically costs $125-150 per cubic yard, depending on location, mix strength, and delivery fees. Minimum orders (usually 1-2 yards) often include extra charges.
