How Many Tons of Gravel in a Cubic Yard? (Conversion Tables)

·6 min read

How many tons of gravel in a cubic yard? About 1.4 tons (2,800 lb) as a working average. That is the number to estimate with. But be honest about it: real aggregate runs roughly 1.2 to 1.7 tons per cubic yard depending on the material, the stone size, and how wet it is. There is no single exact answer, and anyone who gives you one is rounding something off. Use 1.4 to plan, then confirm the actual density with your supplier before you order.

How much does a yard of gravel weigh?

A cubic yard of gravel weighs about 2,800 lb, or 1.4 tons, using the common working average. A cubic yard is 27 cubic feet of material, so you are looking at a pile roughly 3 ft by 3 ft by 3 ft. That is heavy. It is more than most half-ton pickups should carry in one trip.

The spread matters more than the average. At the light end, around 1.2 tons per cubic yard, that same yard weighs 2,400 lb. At the heavy end, around 1.7 tons per cubic yard, it weighs 3,400 lb. Same volume. A thousand pounds apart. That is why the honest answer to "how much does a yard of gravel weigh" is a range with a good default sitting in the middle of it.

How do you convert cubic yards to tons?

Multiply. The formula is simple:

  • tons = cubic yards x 1.4
  • cubic yards = tons / 1.4 (or tons x 0.71)

That is the whole thing. If you know your volume, you know your approximate tonnage. Here is the conversion run out so you do not have to do it in your head:

Cubic yards to tons

  • 1 cubic yard = about 1.4 tons
  • 2 cubic yards = about 2.8 tons
  • 3 cubic yards = about 4.2 tons
  • 5 cubic yards = about 7.0 tons
  • 10 cubic yards = about 14.0 tons

Tons to cubic yards

  • 1 ton = about 0.71 cubic yards
  • 2 tons = about 1.43 cubic yards
  • 3 tons = about 2.14 cubic yards
  • 5 tons = about 3.57 cubic yards
  • 10 tons = about 7.14 cubic yards

Both tables use the 1.4 average. Both are estimates. If your supplier quotes you a different density for the specific product you are buying, use their number instead of mine.

If you have not worked out your volume yet, the Gravel Calculator does the measuring math first. Give it your length, width, and depth and it returns cubic yards plus an approximate tonnage using that same 1.4 average.

Why do suppliers sell by the ton when you measure by volume?

Because they sell what they can weigh. A loader scoop is not a precise measure, but a truck scale is. Yards get argued about. Pounds do not. So the quarry weighs the loaded truck, subtracts the empty weight, and bills you the difference. Clean and verifiable for them.

Your problem runs the other direction. You have a driveway or a bed or a trench. You measured length, width, and depth. That gives you volume, not weight. So you are always translating: volume out of the tape measure, weight into the order form.

Bridging the two is where people go wrong. They calculate 10 cubic yards, multiply by 1.4, order 14 tons, and get a pile that does not match because the actual material was denser or lighter than the average. It is not a math error. It is a density assumption error.

The fix is a short phone call. Ask the supplier: what does a cubic yard of this specific product weigh? They know. They move it every day. Then use their number instead of the generic one, and your order lands where you want it.

Why does gravel weight vary?

Three things move the number, and they stack.

Material type

Not all aggregate is the same rock. Crushed stone, river rock, and pea gravel are different materials with different densities. Some are heavier per scoop than others simply because of what they are made of. This is the biggest single reason two loads of the same volume can weigh noticeably different amounts.

Stone size and shape

Size changes how tightly the pile packs. Small, angular, mixed-size material with fines in it locks together and leaves less air. Large, uniform, rounded stone leaves gaps. More air in the pile means less weight in the same volume. Same rock, different weight, purely because of the void space between the pieces.

Moisture

Wet gravel weighs more than dry gravel. Water fills the voids and adds real weight. A pile that sat out through a heavy rain can throw your conversion off, and you pay for that water by the ton. It matters in both directions. If you are buying by weight after a wet week, you get less rock per ton than you expected. If you are estimating a stockpile you already have, a soaked pile reads heavier than the actual stone in it.

This is also why quarries do not advertise one universal number. They cannot control the weather.

What is the honest range on a real order?

Run the range check on a 10 cubic yard job and the spread gets concrete.

  • At 1.2 tons per cubic yard: about 12 tons
  • At 1.4 tons per cubic yard (average): about 14 tons
  • At 1.7 tons per cubic yard: about 17 tons

So the honest answer for 10 cubic yards is roughly 12 to 17 tons. That is a five ton window. On a small project the gap barely registers. On a big one it is a meaningful difference in what shows up on your driveway and what you get billed for.

This is exactly why 1.4 is a planning number, not a guarantee. It puts you in the middle of the range so you are not badly wrong in either direction. Confirming the real density with your supplier is what closes the window from five tons down to near zero.

How should you use the average without over-ordering?

Work in this order:

  • Measure and get volume. Length x width x depth, converted to cubic yards. The Gravel Calculator handles the unit conversions so you are not fighting inches and feet.
  • Convert with 1.4 for a ballpark. This tells you roughly what tonnage to expect and whether you are ordering a couple of tons or a truckload.
  • Call the supplier with your volume, not your tonnage. Tell them you need X cubic yards of a specific product. Let them do the density conversion with their real number.
  • Add a small buffer for compaction and settling. Gravel settles once you spread and pack it. Most people order a little extra rather than pay for a second delivery.

That last point is worth sitting with. The cost of coming up short is a whole second trip. The cost of coming over is a small leftover pile. The risk is not symmetric, so lean slightly high.

Frequently asked questions

Is a cubic yard of gravel always 1.4 tons?

No. It is an average, not a rule. Common aggregates run roughly 1.2 to 1.7 tons per cubic yard. Use 1.4 to estimate, then confirm the real density for the specific product with your supplier.

How many cubic yards is a ton of gravel?

About 0.71 cubic yards, using the 1.4 average. Ten tons works out to roughly 7.14 cubic yards. Same caveat applies: the actual figure depends on the material you are buying.

Does wet gravel weigh more?

Yes. Water fills the void space between the stones and adds real weight. A rained-on pile is heavier than the same pile dry, which means fewer stones per ton when you buy by weight.

How many cubic feet are in a cubic yard?

27. That is the conversion behind every yardage calculation, including the ones the calculator runs for you.

Bottom line

A cubic yard of gravel is about 1.4 tons, or 2,800 lb, as a working average. Go the other way and a ton is about 0.71 cubic yards. But the real range is roughly 1.2 to 1.7 tons per cubic yard depending on material, stone size, and moisture, which on a 10 cubic yard order is an honest spread of about 12 to 17 tons. Estimate with 1.4. Confirm with your supplier. Run your numbers through the Gravel Calculator to get cubic yards plus an approximate tonnage before you pick up the phone.
