Cubic Yard Calculator
Quickly estimate cubic yards for concrete, gravel, soil, sand, mulch, and fill dirt. This tool helps contractors, landscapers, and homeowners calculate material volume accurately for construction and landscaping projects.
What Is a Cubic Yard?
A cubic yard is a unit of volume used in construction and landscaping. It represents a cube measuring 3 feet in length, width, and height. It is commonly used to measure materials like concrete, gravel, soil, and sand.
How Cubic Yards Are Calculated
To calculate cubic yards, first compute volume in cubic feet, then convert it into cubic yards.
Formula
Cubic Yards = (Length × Width × Depth in Feet) ÷ 27
Depth in Feet = Depth in Inches ÷ 12
Example Calculation
- Length = 20 ft
- Width = 15 ft
- Depth = 6 inches (0.5 ft)
- Volume = 20 × 15 × 0.5 = 150 cu ft
- Cubic Yards = 150 ÷ 27 = 5.56 yd³
Common Material Coverage Table
| Area | Depth | Cubic Yards |
|---|---|---|
| 100 sq ft | 3 inches | 0.93 yd³ |
| 200 sq ft | 3 inches | 1.85 yd³ |
| 500 sq ft | 4 inches | 6.17 yd³ |
| 1,000 sq ft | 4 inches | 12.35 yd³ |
Where Cubic Yards Are Used
- Concrete pouring
- Gravel driveways
- Landscaping projects
- Soil filling
- Mulch and garden beds
- Construction excavation
Why Accurate Volume Estimation Matters
Proper cubic yard calculation prevents over-ordering or under-ordering materials, saving both time and construction costs while improving project efficiency.
Benefits of Proper Material Estimation
- Reduced material waste
- Lower project cost
- Better planning accuracy
- Efficient transportation
- Faster project completion
