How It Works
This calculator uses standard formulas to estimate crushed stone volume and weight:
Volume Calculation
- Rectangle: Volume = Length × Width × Depth
- Circle: Volume = π × Radius² × Depth
- Triangle: Volume = (Length × Width) / 2 × Depth
All measurements are converted to feet before calculation. Volume in cubic feet is then converted to cubic yards by dividing by 27.
Weight Calculation
Weight = Volume (with waste) × Material Density
Conversions
- 1 cubic yard = 0.764554857984 cubic meters
- 1 US ton (short ton) = 907.18474 kg
- 1 inch = 0.0833333 feet
- 1 cm = 0.0328084 feet
- 1 mm = 0.00328084 feet
Recommended Depths
| Application | Recommended Depth |
|---|---|
| Driveways | 3-6 inches |
| Patios | 4-6 inches |
| Walkways | 2-4 inches |
| Landscaping | 1-3 inches |
Material Density Table
| Material Type | Density (tons/yd³) | Density (kg/m³) |
|---|---|---|
| Crushed stone (¼"–2") | 1.5 | ~2700 |
| Crushed stone (2"–6") | 1.65 | ~2970 |
| Limestone | 1.5 | ~2700 |
| Granite | 1.7 | ~3060 |
Frequently Asked Questions
What is the crushed stone calculator used for?
This calculator helps you estimate the volume and weight of crushed stone needed for various projects like driveways, patios, walkways, and landscaping. It accounts for different shapes, depths, material types, and waste factors.
How do I convert cubic yards to tons?
To convert cubic yards to tons, multiply the volume in cubic yards by the material density in tons per cubic yard. The density varies by material type (e.g., 1.5 tons/yd³ for standard crushed stone).
What depth of crushed stone do I need for a driveway?
Typical driveway depths are 3-6 inches. For heavy vehicle traffic, use 4-6 inches. Enter your driveway dimensions and select a depth within this range for an accurate estimate.
How much waste factor should I assume?
A 10% waste factor is standard for most projects to account for compaction, spillage, and irregularities. You can adjust this percentage based on your specific project conditions.
Can I get cost estimate for crushed stone?
Yes, simply enter the price per ton in the optional field, and the calculator will provide a cost estimate based on the total weight of material needed (including waste).
How accurate is this calculator?
This calculator provides reliable estimates for planning purposes. Actual requirements may vary based on site conditions, compaction, and material characteristics. For precise quantities, consult with your supplier.
