How much stone dust you need
Cubic yards = length (ft) × width (ft) × depth (in) ÷ 12 ÷ 27. Tons = cubic yards × 1.56.
Example: a 10 × 10 ft area at 2 inches deep is 16.7 cubic feet, or 0.62 cubic yards. At 1.56 tons per cubic yard that is 0.96 tons, or 34 bags of 0.5 cu ft.
Stone dust is usually a thin leveling or bedding layer; use the depth on your plan.
