How it's calculated

Volume = length × width × depth
Weight = volume × density
1 cubic yard = 27 ft³

Works out the gravel to cover an area to a given depth, as a volume and as a weight (suppliers sell by either). The density depends on the stone and its size; 1.6 t/m³ (about 1.4 US tons per cubic yard) is typical for crushed stone. Allow a little extra for compaction.
