Divide tons by the material’s density in tons per cubic yard: 10 tons of crushed stone ÷ 1.5 = 6.7 cubic yards, while 10 tons of topsoil ÷ 1.1 = 9.1 cubic yards. The material matters — there is no universal tons-to-yards number.

Tons to Cubic Yards — Turning a Quote Back into Volume
Suppliers think in weight because their trucks cross a scale; you think in volume because your project is a hole with dimensions. So when the quote comes back “12 tons, delivered,” the first question is always the same: how much space is that? The answer is cubic yards = tons ÷ density — 12 tons of crushed stone ÷ 1.5 tons per yard = 8 cubic yards. This calculator runs that division for any material and any weight unit, tons or tonnes.
This direction of the conversion is your quality-control tool. Convert every tonnage quote to yards before accepting it, then compare that volume against your own measurement. If the supplier’s 12 tons works out to 8 yards and your excavation needs 9.5, the shortfall surfaces now — on the phone — instead of at 4 p.m. with an empty pile and an unfinished base.
What Volume Does a Tonnage Quote Fill?
| Quote (crushed stone) | Cubic yards | Covers at 3 in | Covers at 4 in |
|---|---|---|---|
| 3 tons | 2.0 yd³ | 216 sq ft | 162 sq ft |
| 5 tons | 3.3 yd³ | 360 sq ft | 270 sq ft |
| 10 tons | 6.7 yd³ | 720 sq ft | 540 sq ft |
| 15 tons | 10.0 yd³ | 1,080 sq ft | 810 sq ft |
| 20 tons | 13.3 yd³ | 1,440 sq ft | 1,080 sq ft |
The table assumes crushed stone at 1.5 tons per yard; lighter materials stretch further. The same 10-ton quote becomes 7.1 yards as gravel, 7.4 yards as pea gravel, and 9.1 yards as topsoil — while dense riprap shrinks it to 6.1. Never carry a conversion from one material’s quote to another’s.
Reading Quotes Like a Contractor
- Confirm the weight unit first. A “ton” on a US quote is 2,000 lb; a tonne on an import or metric quote is 2,204.6 lb. On a 20-ton order the difference is a full truck axle’s worth of stone.
- Check the quote against truck capacity. A tandem dump truck legally hauls 13–15 tons. A 14-ton quote is one clean trip; a 16-ton quote means two deliveries — ask whether the second trip carries its own fee.
- Ask which density they scale with. Quarries know their own rock, and a local limestone may run 1.55 rather than the generic 1.5. Their number is the one that decides how many yards your money buys.
- Compare quotes in one unit only. When yard A quotes per ton and yard B per cubic yard, convert both to price per yard before choosing — the cheaper-sounding ton price loses this comparison surprisingly often.
Going the other way — from your measured volume to an order weight — is the job of the cubic yards to tons calculator. And if what you really have is an area and a depth rather than yards, the square feet to tons calculator skips the intermediate step entirely.
Frequently Asked Questions
How many cubic yards is 10 tons of gravel?
About 7.1 cubic yards — divide 10 tons by gravel’s density of 1.4 tons per cubic yard. For denser crushed stone at 1.5, the same 10 tons is only 6.7 cubic yards.
Why does the material change the conversion?
Because a cubic yard is a volume and a ton is a weight, the conversion runs through density. Dense materials pack more weight into the same yard: riprap hits 1.65 tons per yard while lava rock is only 0.65 — a 2.5× difference for the identical volume.
Is a ton the same as a tonne here?
No. This converter uses US short tons (2,000 lb). A metric tonne is 2,204.6 lb — about 10% more. If your quote is in tonnes, select tonnes as the input unit and the calculator handles the difference.
How many tons fit in a standard dump truck?
A tandem-axle dump truck typically hauls 13–15 tons of stone (about 9–10 cubic yards); single-axle trucks carry 6–9 tons. Converting your tonnage to yards tells you whether the order fits in one load.
