Cubic Yards to Tons: Which Unit Should You Order?
Cubic yards measure volume, tons measure weight, and the conversion depends on material density for gravel, sand, soil, mulch, and other bulk materials.

Quick answer
In short
- Formula: Tons = cubic yards x material density in tons per cubic yard.
- Reverse: Cubic yards = tons / material density.
- Best practice: Use your supplier density for ordering, not a universal conversion.
Use the calculators: Start with the Cubic Yard Calculator, estimate gravel with the Gravel Calculator, and check measurement units with the Unit Converter. Browse Construction Calculators.
Planning estimate only: Density changes with material type, moisture, gradation, compaction, and supplier specs. Confirm the conversion factor before ordering.
Quick answer
Use cubic yards when you are filling a measured space. Use tons when the supplier sells heavy aggregate by weight. For many projects, calculate cubic yards first and then convert to tons.
Cubic yards to tons formula
Tons = cubic yards x tons per cubic yard Cubic yards = tons / tons per cubic yard
Worked examples
| Project | Volume | Density | Estimated tons |
|---|---|---|---|
| Small gravel pad | 3 yd3 | 1.4 tons/yd3 | 4.2 tons |
| Driveway refresh | 8 yd3 | 1.5 tons/yd3 | 12 tons |
| Large driveway | 20 yd3 | 1.45 tons/yd3 | 29 tons |
Why material density changes the answer
- Gravel, sand, soil, mulch, and crushed stone weigh differently.
- Wet material can weigh more than dry material.
- Compacted material may fill less space than loose material.
- Stone size and fines content change bulk density.
Driveway workflow
For a driveway, measure length and width, choose depth, calculate cubic yards, then convert to tons if the supplier sells by weight. Pair this guide with the Gravel Driveway Calculator guide, Gravel Driveway Cost Guide, and depth and overage guide.
Common mistakes
- Assuming one cubic yard always equals one ton.
- Using gravel density for mulch or soil.
- Ignoring moisture and compaction.
- Ordering without checking whether the supplier quotes yards or tons.
FAQs
How many tons are in a cubic yard?
It depends on the material density.
How many cubic yards are in a ton of gravel?
Divide 1 ton by the gravel tons-per-cubic-yard factor. At 1.5 tons per yard, 1 ton is about 0.67 cubic yards.
Is gravel sold by the yard or ton?
Either can happen, but many aggregate suppliers sell by the ton.
Should I order extra material?
Often yes for compaction, uneven ground, spreading loss, and future touch-up.
Cubic yards and tons are different units. Calculate volume first, then convert using supplier density when the material is sold by weight.
