How to Use This Calculator

  2. Enter the desired depth in inches.
  3. Select the material type from the dropdown.
  4. Click "Calculate Tonnage" for volume and weight estimates.

The Formula

Volume (cu yd) = (Length × Width × Depth÷12) ÷ 27
Tons = Volume × Material Density

Densities used: Gravel = 1.4 t/cy, Sand = 1.35 t/cy, Crushed Stone = 1.5 t/cy, Topsoil = 1.1 t/cy. Actual density may vary — confirm with your supplier.
