Stone Weight Calculator
Estimate the total weight of stone needed based on volume and material type.
Stone Weight Calculator - Convert Tons and Pounds for Stone Material
The stone weight calculator converts between volume and weight measurements for bulk stone materials. Since most suppliers sell by weight (tons or pounds), you need to convert your cubic yard calculations into tons for ordering. This calculator simplifies the conversion using material-specific density factors.
Different stone types have different densities, affecting weight-to-volume conversions. Crushed stone typically weighs 1.3-1.5 tons per cubic yard, while gravel may weigh 1.2-1.4 tons per cubic yard. The calculator accounts for these variations, ensuring accurate weight estimates for driveways, patios, and other projects.
Weight calculations are essential for transportation planning, cost estimation, and structural design. Knowing the exact tonnage ensures you order the correct amount from suppliers who price by weight. For detailed weight calculations of individual items, see our stone slab weight calculator.
Frequently Asked Questions
How do I convert cubic yards to tons?
Multiply cubic yards by material density (tons per cubic yard). Standard densities: crushed stone 1.4 tons/yd³, gravel 1.2 tons/yd³. Our calculator handles this automatically for all material types.
Why do suppliers sell by weight instead of volume?
Weight is more consistent and fair. A ton is always 2,000 pounds regardless of packing. Volume varies with moisture and settling. Weight-based pricing ensures both parties know exactly what they're getting.
How accurate are weight estimates?
Our estimates use industry-standard densities and are reliable for budgeting. Actual weight may vary slightly based on moisture content and material composition. Confirm material-specific density with your local supplier for precise ordering.
What's included in material weight?
Material weight refers to the stone only, not moisture or debris. Ensure you order 'clean' stone without excessive fine particles that might affect actual weight and coverage.
Do I need to account for compaction when calculating weight?
Weight doesn't change with compaction—the stone itself weighs the same compacted or loose. However, you need to order more loose volume to achieve your desired compacted depth. See our compaction calculator for volume adjustments.
How do I calculate delivery costs based on weight?
Most suppliers charge per ton for delivery. Calculate total tons needed, then multiply by the per-ton delivery fee. Our weight calculator provides the tonnage you need for accurate delivery cost estimates.
