Calculate mulch cubic yards or bags from bed area and depth. Estimate wood mulch, bark, and rubber mulch for landscaping beds and garden paths.
Calculate topsoil cubic yards for lawn grading, garden beds, and raised areas. Enter coverage area and depth for yards, tons, and bag counts.
Free concrete calculator for slabs, footings, and pours. Enter length, width, depth to get cubic yards, cubic feet, and bag counts with waste factor.
Convert depth from inches to feet before calculating volume. Irregular areas: sum rectangles or use average width.
Cubic Yards = (Length × Width × Depth in ft) ÷ 27Crushed limestone and gravel weigh ~1.4–1.6 tons per cubic yard depending on moisture and size.
Tons = Cubic Yards × Material Density (1.4–1.6 tons/cu yd)Quick reference: multiply sq ft by depth in inches, divide by 324 for cubic yards.
1 cu yd covers ≈ 100 sq ft at 3″ depthUpdated: July 2026
600 × 4/12 ÷ 27 = 7.4 cu yd. Order 8 yards (~11 tons). Compact in lifts with plate compactor.
50 sq ft trench cross-section at 1 ft depth = 50 cu ft ≈ 1.9 cu yd pea gravel surround pipe.
80 × 2/12 ÷ 27 = 0.5 cu yd. Small order — bags (0.5 cu ft) may cost more than bulk minimum delivery.
Estimate crushed stone, pea gravel, or road base for driveways, French drains, and landscaping. Enter coverage area and depth to get cubic yards, weight in tons, and number of dump truck loads.
