How Many Yards in a Ton?
If you're ordering gravel, soil, crushed stone, sand or other bulk materials, one of the most common questions is: how many yards in a ton? The answer depends on the material density because a cubic yard of one material may weigh significantly more or less than another.
This Yards to Tons Calculator helps contractors, landscapers, engineers and homeowners convert cubic yards into tons using material-specific density values. Whether you're estimating gravel for a driveway, stone for a construction project or soil for landscaping, this calculator provides fast and accurate conversions.

Yards to Tons Formula
Converting cubic yards into tons requires a density value.
Forward Formula
Tons = Material Weight Cubic Yards = Material Volume Density = Material Weight per Cubic Yard
Tons = Cubic Yards × Density
Reverse Formula
Use this formula when determining how many yards are contained within a specific tonnage.
Cubic Yards = Tons ÷ Density
Variables Used in Yards to Tons Conversion
The density value is the most important factor in any yards-to-tons conversion.
| Variable | Description |
|---|---|
| CY | Cubic Yards |
| TON | Tons |
| D | Density |
| WT | Material Weight |
How Do You Convert Yards to Tons?
- Identify the material type (gravel, sand, stone, soil, etc.).
- Use the preset density or enter a custom density in tons per cubic yard, lb/ft³, or kg/m³.
- Enter cubic yards or tons — the other value updates automatically.
- Use the swap button to enter tons and solve for cubic yards (how many yards in a ton).
Worked Example - Gravel Conversion
Project: Gravel Volume = 20 cubic yards, Density = 1.5 tons per cubic yard.
Step 1: Apply Formula
Tons = 20 × 1.5 Tons = 30
Result
20 cubic yards of gravel requires approximately 30 tons.
Material Density Conversion Table
Typical tons per cubic yard by material. Actual values vary by moisture content and material composition.
| Material | Tons per Cubic Yard |
|---|---|
| Gravel | 1.4 – 1.6 |
| Crushed Stone | 1.4 – 1.6 |
| Limestone | 1.3 – 1.5 |
| Sand | 1.2 – 1.4 |
| Topsoil | 1.1 – 1.3 |
| Fill Dirt | 1.2 – 1.4 |
| Asphalt | 1.9 – 2.2 |
| Concrete | 1.8 – 2.0 |
| Mulch | 0.5 – 0.8 |
Engineering Notes
How Many Yards in a Ton?
The number of yards in a ton depends on the material. Gravel and crushed stone are typically about 0.67 yd³ per ton (at ~1.5 tons/yd³). Sand is about 0.74 yd³ per ton. Topsoil about 0.75 yd³ per ton. Mulch can exceed 1.3–2.0 yd³ per ton because it is much less dense.
How Many Cubic Yards in a Ton?
For gravel at 1.5 tons per cubic yard: 1 ÷ 1.5 ≈ 0.67 cubic yards per ton. Always use the correct density for accurate conversions.
Material Density Matters
The conversion between yards and tons changes depending on material density. There is no universal answer for all materials.
Moisture Content
Wet materials generally weigh more than dry materials. Rainfall and storage conditions may affect actual tonnage.
Supplier Variations
Different suppliers may use slightly different density values. Always verify density when ordering large quantities.
Construction Estimating
Many contractors add 5% to 10% extra material to account for waste, settlement and compaction.
Common Conversion Mistakes
Assuming All Materials Have the Same Density
This is the most common error when converting yards to tons.
Using Generic Conversion Factors
Different materials require different conversion factors.
Ignoring Moisture Content
Wet materials can significantly increase tonnage.
Ordering Exact Quantities
Small estimation errors can create shortages. Most projects include a contingency allowance.
Using Incorrect Units
Verify whether measurements are cubic yards, tons, metric tons or cubic meters.
FAQ
