Stone Tonnage Calculator
Calculate the total tonnage of stone required for purchasing.
Quick Answer
To convert a stone project to tons, find the volume in cubic yards (length × width × depth in feet ÷ 27), then multiply by the material's density — about 1.4–1.5 tons per cubic yard for most stone. So 5 cubic yards of crushed stone is roughly 7.5 tons.
Stone Tonnage Calculator (Cubic Yards to Tons) Guide
The stone tonnage calculator solves the mismatch that catches out most first-time buyers: you plan a project by its area and depth to find the required volume (in cubic yards), suppliers price and sell materials by weight (in tons). This calculator seamlessly converts your volume into the tonnage you need to order.
The conversion relies on the density of the specific material you choose. By selecting your stone type, the tool applies the correct density factor to provide an accurate weight estimate. This prevents confusion at the supply yard and ensures you purchase the correct amount of material for your job. Different stone types have different densities: crushed stone typically weighs 1.3-1.5 tons per cubic yard, while lighter materials like sand may weigh 1.2-1.3 tons per cubic yard. If you have been looking for a stone calculator in tons, this is exactly that—enter your volume and it returns the order weight directly in tons.
Understanding tonnage is essential for several reasons. First, most suppliers sell by weight, so you need tonnage to place orders and compare prices. Second, transportation costs are often based on weight, affecting delivery expenses. Third, weight helps you understand material handling requirements and equipment needs. For volume-based planning, use our stone yard calculator to determine cubic yards first, then convert to tons using this calculator.
The calculator accounts for material-specific densities and provides accurate conversions between volume and weight. It also allows you to work in reverse—entering weight to determine volume—which is useful when suppliers provide weight-based quotes and you need to understand coverage area or depth capabilities.
Tons Per Cubic Yard by Material
Standard bulk densities this calculator uses (US short tons):
| Material | Tons per yd³ | 1 ton ≈ |
|---|---|---|
| Sand | 1.60 | 0.63 yd³ |
| Crushed stone | 1.50 | 0.67 yd³ |
| River rock | 1.45 | 0.69 yd³ |
| Gravel | 1.40 | 0.71 yd³ |
| Pea gravel | 1.35 | 0.74 yd³ |
| Topsoil | 1.10 | 0.91 yd³ |
Sources & Methodology
Volume-to-weight results use standard aggregate bulk densities (for example, crushed stone ≈ 1.5 US tons per cubic yard) applied consistently across this site, and pricing reflects 2026 U.S. supplier averages that vary by region and delivery. All results are planning estimates — confirm the exact density and price with your local supplier before ordering.
Frequently Asked Questions
Why is stone sold by the ton?
Weight is a more consistent and reliable measure for bulk materials than volume. A ton is always 2,000 pounds, whereas the volume of a pile of stone can vary with moisture and stacking. Selling by weight is the industry standard for fairness and accuracy.
How many tons are in a cubic yard of gravel?
A cubic yard of typical gravel weighs approximately 1.4 tons (2,800 pounds). However, this can vary slightly based on the specific type and size of the gravel. Our calculator uses standard densities for its estimates and allows you to select specific material types for more accurate conversions.
How many cubic feet are in a ton of stone?
There are roughly 20-22 cubic feet in a ton of crushed stone. This number changes based on the stone's density. Denser materials will have fewer cubic feet per ton, while lighter materials have more cubic feet per ton. The calculator accounts for material-specific densities.
What is the difference between a ton and a tonne?
A "ton" in the US refers to a short ton, which is 2,000 pounds. A "tonne" (or metric ton) is 1,000 kilograms, or about 2,204.6 pounds. Landscaping materials in the US are sold by the short ton (2,000 pounds), which is what this calculator uses.
How do I convert cubic yards to tons?
Multiply cubic yards by the material's density in tons per cubic yard. Typical stone densities range from 1.2-1.5 tons per cubic yard. For example, 5 cubic yards of crushed stone × 1.4 tons/yd³ = 7 tons. Our calculator automates this conversion based on your selected material type.
Can I trust the weight estimate from this calculator?
Yes, our calculator uses industry-standard density figures to provide very reliable estimates for budgeting and ordering. It's an excellent tool for planning your purchase. For precise ordering, always confirm density with your specific supplier, as moisture content and material variations can cause slight differences.
