Tons to Cubic Yards Calculator
Converting between weight and volume is essential for construction, landscaping, and excavation projects. A tons to cubic yards calculator uses material density to estimate how many cubic yards you need for a given weight of gravel, sand, topsoil, mulch, or crushed stone. This guide explains density-based conversion, material-specific factors, and how to plan for compaction and delivery.
Why Tons and Cubic Yards Differ
Tons measure weight, while cubic yards measure volume. The same weight of different materials occupies different volumes depending on density. Dense materials like concrete occupy fewer cubic yards per ton, while light materials like mulch occupy more.
| Material | Density (tons/yd³) | Cubic Yards per Ton |
|---|---|---|
| Gravel | 1.35 | 0.74 |
| Sand | 1.30 | 0.77 |
| Topsoil | 1.20 | 0.83 |
| Mulch | 0.80 | 1.25 |
| Concrete | 2.40 | 0.42 |
| Asphalt | 2.00 | 0.50 |
| Limestone | 1.50 | 0.67 |
| Clay | 1.80 | 0.56 |
How the Calculator Works
The calculator divides the total weight in tons by the material density in tons per cubic yard.
| Variable | Formula | Example |
|---|---|---|
| Weight | Tons provided | 10 tons |
| Density | Material-specific | 1.35 tons/yd³ for gravel |
| Cubic yards | Weight / Density | 10 / 1.35 = 7.41 yd³ |
| Compacted volume | Loose volume x compaction factor | 7.41 x 0.85 = 6.30 yd³ |
Always add a small buffer for settling and moisture.

Material Density Factors
Density varies by moisture content, particle size, and compaction method.
| Factor | Effect on Density | Example Impact |
|---|---|---|
| Moisture content | Increases weight | Wet sand is heavier than dry |
| Particle size | Larger rocks = less voids | Crushed stone packs tighter |
| Compaction | Reduces volume | Vibratory plate compactor |
| Screening | Uniform sizes | Sorted gravel vs mixed |
| Organic content | Decreases density | Decaying mulch is lighter |
Compaction and Settlement
Materials settle after delivery. Order slightly more than the calculated volume to account for settling.
| Material | Compaction Factor | Recommended Overage |
|---|---|---|
| Gravel | 0.85 - 0.90 | 10-15% |
| Sand | 0.80 - 0.85 | 15-20% |
| Topsoil | 0.75 - 0.85 | 15-25% |
| Mulch | 0.70 - 0.80 | 20-30% |
| Concrete | 0.95 - 1.00 | Minimal |
| Asphalt | 0.90 - 0.95 | 5-10% |
Use Cases and Applications
| Use Case | Why Accurate Conversion Matters |
|---|---|
| Driveway gravel | Order too little and you need another delivery |
| Landscape beds | Overordering waste money on unused mulch |
| Concrete pours | Underordering causes project delays |
| Road base | Compacted volume differs from loose volume |
| Drainage rock | Voids between stones affect total volume |
| Fill dirt | Settlement changes final grade |
Common Material Pricing
Understanding volume-to-weight conversion helps compare prices.
| Material | Price per Ton | Price per Cubic Yard | Typical Use |
|---|---|---|---|
| Gravel | $25 - $55 | $35 - $75 | Driveways, drainage |
| Sand | $15 - $45 | $20 - $60 | Playgrounds, concrete |
| Topsoil | $20 - $50 | $25 - $55 | Gardens, lawns |
| Mulch | $30 - $60 | $25 - $50 | Landscaping beds |
| Concrete | $100 - $150 | $240 - $360 | Foundations, slabs |
| Asphalt | $80 - $120 | $160 - $240 | Paving, roads |
Delivery and Truck Capacities
Know your truck sizes to plan deliveries efficiently.
| Truck Type | Capacity (Cubic Yards) | Equivalent Tons (Gravel) |
|---|---|---|
| Small pickup | 0.5 - 1 | 0.5 - 0.7 |
| Dump truck | 10 - 15 | 7.5 - 10.5 |
| Semi-trailer | 20 - 30 | 15 - 20.5 |
| Buggy | 3 - 5 | 2.5 - 3.75 |
| Wheelbarrow | 0.1 - 0.2 | 0.08 - 0.15 |
Conclusion
A tons to cubic yards calculator is essential for any material ordering project. By entering your material type and total weight, you get an accurate volume estimate for ordering and delivery. Use the calculator above, account for compaction, and always order a small buffer to avoid costly second deliveries.
