Why Yards and Tons Are Different Numbers

Yards measure volume. Tons measure weight. The conversion depends on the material.

A cubic yard is a fixed box — 3 feet by 3 feet by 3 feet, 27 cubic feet of space. What that box weighs depends entirely on what’s inside it. ABC Aggregate Base Course -- crushed stone with fines mixed in; the standard driveway and pad base material in NC gravel packs dense and wet clay-bound fines add mass. Washed #57 stone drains fast but has more air between particles.

Contractors typically quote jobs in cubic yards because that’s what fills a space. Quarries bill in tons because that’s what the truck scale reads at the gate. Both numbers are correct — they just measure different things. The homeowner holding a gravel delivery ticket sees tons; the quote said yards. Nothing changed. The conversion is the answer.

This is the single most common source of “did I get shorted?” calls in NC hauling. You probably weren’t shorted. Run the converter above and check.

How to Read a Delivery Ticket

The ticket shows three things worth verifying: material type, net weight in tons, and sometimes the quarry of origin.

Walk through it line by line when the truck pulls away:

• Material name: Should match what your contractor spec’d. “ABC 57” is not the same as “#57 stone” — one is base course, one is drainage stone. Confirm the spec before the truck rolls, not after.
• Net weight (tons): This is what the quarry scale measured at load-out. It is the most reliable number on the ticket — scale readings are regulated.
• Quantity in yards (if listed): Cross-check against the converter using the actual material on the ticket. A 10% variance from the midpoint estimate is normal across different quarries and moisture levels.

If something looks off, ask for the quarry scale ticket. A legitimate contractor can produce it; refusal to do so is a recognized warning sign in a grading bid. The quarry scale ticket is the original record of what left their facility — it is not the same as the delivery receipt the driver hands you.

Short-Load Red Flags

Short loads are rare but real. Here’s what actually looks wrong — versus what just looks confusing.

A ticket significantly below the low end of the expected range — more than 15% under the minimum — is the clearest signal. The converter gives you that floor. If 5 yards of CABC Crusher Run Aggregate Base Course -- similar to ABC but less tightly graded; common in price-sensitive base applications should weigh at minimum 7.0 tons and the ticket shows 5.8 tons, ask before signing.

Substituted material is the other pattern. You ordered #67 washed stone and the ticket says “crusher run” — that is not the same material. Crusher run has fines that block drainage. Verify the spec on the ticket matches the spec on your quote.

Neither of these situations requires a legal confrontation. Ask the contractor for the quarry scale ticket. A straightforward supplier hands it over without a second thought.
