Cubic Yard Calculator (Volume & Material Weight)

Enter length, width, and depth to get the volume in cubic yards, along with cubic meters and cubic feet. It also estimates weight using built-in densities for concrete, gravel, sand, topsoil, mulch, and wet clay.

How to use
  1. Enter length, width, and depth with your chosen units.
  2. Pick a material to set the density.
  3. Check the estimated weight in US and metric tons.

How it's calculated

yd³ = (L × W × D) ÷ 0.764555

L, W, D = length, width and depth converted to metres; their product is the volume in m³, divided by 0.764555 m³/yd³ to give cubic yards. 1 yd³ ≈ 27 ft³.

Common questions

How do I find cubic yards?

Multiply length, width, and depth in feet, then divide by 27, since one cubic yard is 27 cubic feet.

Why does material matter for weight?

Each material has its own density, so the same cubic yard of gravel weighs much more than the same volume of mulch.
