How do I figure how much rock is needed to cover a given area. This will be 2"
rock. Any conversion tables out there? Thanks.

Calculate the volume:

width X length X 2/12 = cu ft [2/12 is depth in ft]
[width and length in ft]


cu ft/27 = cu yd

The supplier will be able to tell you how many tons per cubic yard for the material of interest. The factor might be something like 1.2T/cu yd, but the 1.2 will vary depending upon the stone of interest.

A ton normally covers 50 sq ft as a ground cover
