Gravel, Base, and Asphalt Tonnage Calculator

Turn length, width, and depth into cubic yards and tons. Pick the material or type your own density.

Estimate only. Densities change with the material, moisture, and compaction. Get the real number from your supplier or the mix design.

How the math works

Cubic feet = L(ft) x W(ft) x (Depth in / 12) x (1 + waste% / 100)
Cubic yards = cubic feet / 27
Tons = cubic feet x density (lb/cu ft) / 2000

The material densities in the list are rough typical values. Base rock that gets compacted takes more tons than the loose volume suggests, so ask your supplier how they sell it.
