6 Cubic Yards of Road Base in Tons
6 cubic yards of road base in tons works out to about 9.0 tons using a planning weight of 1.5 tons per yard. Real loads land between roughly 8.4 and 9.9 tons depending on stone size, fines and moisture. That is about 18,000 pounds.
Volume and tonnage calculator →The conversion
- Yards × tons per yard: 6 × 1.5 = 9.0 tons.
- Low end: 6 × 1.4 = 8.4 tons.
- High end: 6 × 1.65 = 9.9 tons.
If your supplier quotes a different weight per yard, multiply by theirs.

About road base
Road base (also called base rock, ABC, or Class 2 base in different states) is a graded mix of stone and fines made to compact into a load-bearing layer.
Hauling 6 yards
Plan the delivery around 9.0 tons: one small truck in most areas. A pickup is a poor fit for anything past a fraction of a yard; see how much gravel a half-ton pickup can carry.
Before you order
- Confirm whether the yard prices road base by the ton or by the yard.
- Add about 10 percent for compaction and uneven ground.
- Clear a firm spot for the truck to dump.
The volume and tonnage calculator converts any area and depth into yards and tons.
Good and poor uses for road base
Works well for:
- Base under asphalt and concrete
- Gravel roads and drives
- Equipment and shed pads
Less suited to:
- Drainage layers
- Decorative surfaces
- Surfaces that will stay uncompacted
Quick reference numbers
- Per inch over 100 sq ft: about 0.46 tons of road base (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.6 tons.
- Another size for comparison: a 20x25 area at 4 inches takes about 9.3 tons.
- Weight used here: about 1.5 tons per cubic yard.
Where estimates go wrong
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.

Either works; just convert with the supplier’s own weight per yard so the two quotes compare fairly.
