公式
## How to Calculate Gravel Needed ### Formula **Cubic Yards = (Length × Width × Depth in feet) / 27** **Tons = Cubic Yards × 1.4** Gravel weighs approximately 2,800 lbs (1.4 tons) per cubic yard. This can vary from 1.3 to 1.5 tons depending on the type and moisture content.
计算示例
A driveway 30 ft long, 10 ft wide, with 3 inches of gravel.
- 01Depth in feet: 3 / 12 = 0.25 ft
- 02Volume = 30 × 10 × 0.25 = 75 cu ft
- 03Cubic yards = 75 / 27 = 2.78 cu yd
- 04Tons = 2.78 × 1.4 = 3.89 tons
常见问题
How many tons of gravel in a cubic yard?
Approximately 1.4 tons per cubic yard of gravel, though this varies by gravel type. Pea gravel is about 1.4 tons, crushed stone is about 1.4 tons, and river rock can be up to 1.5 tons.
How deep should a gravel driveway be?
A gravel driveway should be 4-6 inches deep with a compacted base. Use 3 layers: 4 inches of #3 stone base, 2 inches of #57 stone, and 2 inches of surface stone.
How much does a ton of gravel cover?
One ton of gravel covers approximately 80-100 sq ft at 2 inches deep, or about 50-60 sq ft at 3 inches deep.
