Gravel & Road Base Calculator (Tons)
Turn an area and depth into cubic yards and tons of road base, gravel, crushed stone, sand or topsoil.
Tons needed
4.07 tons
- Cubic yards (with extra)
- 2.72 yd³
- Metric tonnes
- 3.70 t
- Pounds
- 8,148 lb
- Density used
- 1.5 tons/yd³
Densities in the list are rough typical figures — they change with moisture and compaction, so use your supplier's number when you have it.

Cubic yards (ft³ ÷ 27), plus extra for compaction
yd³ = length × width × (depth ÷ 12) ÷ 27 × (1 + extra ÷ 100)
20 × 10 × (4 ÷ 12) ÷ 27 × (1 + 10 ÷ 100) = 2.71605 yd³
Tons: cubic yards × density
tons = yd³ × density
2.71605 × 1.5 = 4.07 tons
How it works
Cubic yards = length × width × depth ÷ 27 × (1 + extra); tons = cubic yards × density (tons per yd³)
