How many tons in a cubic yard of dirt?
Quick Answer
A cubic yard of average topsoil weighs approximately 1.1 tons (2,200 lbs). Dry fill dirt weighs about 1.0–1.1 tons per cubic yard, while compacted or wet clay-heavy soil can weigh 1.5–1.7 tons per yard. Sandy soil is on the lighter end at 1.0–1.1 tons per yard.
Quick Reference Table
| Soil type | Weight per cubic yard |
|---|---|
| Dry topsoil | ~1.1 tons (2,200 lbs) |
| Moist topsoil | ~1.35 tons (2,700 lbs) |
| Dry fill dirt | ~1.0–1.1 tons |
| Wet clay soil | ~1.5–1.7 tons |
| Sandy loam | ~1.1–1.3 tons |
| Compacted fill | ~1.25–1.35 tons |
How to Calculate It Yourself
- 1
One cubic yard = 27 cubic feet.
- 2
Typical topsoil density: 80–90 lbs per cubic foot.
- 3
27 × 85 lbs/cu ft = 2,295 lbs ≈ 1.15 tons per cubic yard.
- 4
For wet clay: 27 × 115 lbs/cu ft = 3,105 lbs ≈ 1.55 tons per yard.
- 5
To convert tons to cubic yards: tons ÷ 1.1 = approximate cubic yards of topsoil.
Pro Tip
When ordering topsoil or fill dirt, ask for the weight per yard from your supplier — it varies significantly with moisture content. Fresh-delivered soil is often much heavier than dry stored soil.
