Yards, tons, and truckloads for gravel and crushed stone. Driveways usually run 4 inches of base plus 2 to 3 inches of surface stone.
Pro habit: Order about 2.7 yd³ to cover compaction and low spots; crushed stone locks in about 10 to 15 percent tighter than it arrives.
Suppliers often sell by the ton; use the tons number when you call, and confirm their conversion since moisture changes weight. Weights are common industry approximations; confirm with your supplier before ordering.

Multiply length by width by depth in feet, then divide by 27 to get cubic yards. This gravel calculator does it for you: enter length and width in feet and depth in inches, and it returns cubic yards, estimated tons, and truckloads. Add about 10 percent for compaction, spillage, and uneven grade.
Gravel runs roughly 1.40 tons per cubic yard as a common industry approximation (Crushed stone / QP / item 4 at about 2,800 lb/yd³). Moisture and material change this, so confirm the exact conversion with your supplier.
