Cubic Yard Calculator Guide
A cubic yard is the standard unit of volume measurement for aggregate materials like topsoil, gravel, mulch, and concrete. One cubic yard is equal to 27 cubic feet (3ft x 3ft x 3ft). Knowing the exact yardage prevents you from overpaying for material you don't need or halting a project because you ran short.
How to Calculate Cubic Yards
The basic formula depends on the shape of your project:
- Rectangle: (Length × Width × Depth) ÷ 27
- Circle: (π × Radius² × Depth) ÷ 27
- Triangle: (0.5 × Base × Height × Depth) ÷ 27
Important: All dimensions must be in feet before multiplying. If your depth is in inches, you must divide it by 12 first.
Common Material Weights
- Topsoil: ~2,100 lbs per yard (approx 1 ton).
- Gravel/Stone: ~2,800 lbs per yard (approx 1.4 tons).
- Concrete: ~4,000 lbs per yard (approx 2 tons).
- Mulch: ~600-800 lbs per yard (very light).
