Tons to Cubic Yards: How to Convert Gravel, Sand, and Dirt

A cubic yard of gravel weighs roughly 1.4 short tons, about 2,800 pounds. So to convert cubic yards to tons, multiply by 1.4. To go the other way, divide tons by 1.4. That single rule covers most gravel orders, and we'll cover sand and dirt below too.

The math sounds simple, but it trips people up because suppliers quote prices two different ways. Some sell by the ton. Some sell by the cubic yard. If you don't know how to flip between them, you can't tell which quote is actually cheaper. Let's fix that.

Key Takeaways

• A cubic yard of gravel weighs about 1.4 short tons (2,800 lb), so tons = yards × 1.4.
• To convert tons back to yards, divide by 1.4: yards = tons ÷ 1.4.
• Sand, topsoil, and crushed stone all have different densities, so use the table below.
• Moisture and material type shift real weight, sometimes by 10 percent or more (USDA NRCS, 2023).

How Do You Convert Tons to Cubic Yards?

To convert tons to cubic yards, divide the tonnage by the material's density in tons per cubic yard. For gravel, that density is about 1.4, so 10 tons divided by 1.4 equals roughly 7.1 cubic yards. Industry references peg dry gravel near 2,800 pounds per cubic yard (USGS, 2022).

Here's the plain formula, both directions:

• Tons to cubic yards: yards = tons ÷ density
• Cubic yards to tons: tons = yards × density

The only variable you need is density, and that changes with the material. Wet sand weighs more than dry gravel. Crushed stone packs tighter than loose topsoil. So before you run the numbers, grab the right figure from the table in the next section.

At checkout, WAYS converts your order using each product's real measured density, not a generic average, so the yards-to-tons math matches what actually lands in your driveway.

To convert tons to cubic yards, divide tons by the material's density. Gravel runs about 1.4 tons per cubic yard (2,800 lb), so 10 tons equals roughly 7.1 cubic yards (USGS, 2022). The same formula works for sand and dirt with their own densities.

How Many Tons Are in a Cubic Yard of Gravel, Sand, and Dirt?

A cubic yard of gravel holds about 1.4 tons, sand runs 1.3 to 1.4 tons, and topsoil sits near 1.0 to 1.3 tons depending on moisture. Densities vary because each material has a different grain size and water content (USDA NRCS, 2023). The table below gives working figures you can quote.

Figures are rounded industry averages drawn from federal soil and minerals data (USGS, 2022; USDA NRCS, 2023). Treat them as starting points. Moisture is the big swing factor: a rain-soaked pile of sand can weigh 10 to 15 percent more than the same sand bone-dry. Grain size matters too, since fine material settles tighter than chunky stone.

We've loaded the same product on a dry July morning and after a three-day soak, and the scale ticket can move noticeably. That's why a real weight beats a textbook number every time.

A cubic yard of gravel weighs about 1.4 tons (2,800 lb), sand 1.3 to 1.5 tons depending on moisture, and topsoil near 1.1 tons (USGS, 2022). Wet material can weigh 10 to 15 percent more than dry.

What Does a Real Conversion Look Like?

Worked examples make this stick. Most orders come in one of two forms: you know the tonnage and need yards, or you know the yards and need tons. Gravel's density of 1.4 tons per cubic yard handles both (USGS, 2022). Here are two common gravel orders run both directions.

"I Need 10 Tons of Gravel. How Many Yards Is That?"

Divide tons by density. 10 tons ÷ 1.4 = about 7.1 cubic yards. So a 10-ton gravel order fills roughly 7 cubic yards of space. If you measured your project in yards and a quote came back in tons, this is the flip you need to compare it fairly.

"I Need 6 Cubic Yards of Gravel. How Many Tons Is That?"

Multiply yards by density. 6 yards × 1.4 = 8.4 tons. So six cubic yards of gravel weighs roughly 8.4 short tons. A standard tandem dump truck handles this easily, which matters for delivery planning. See how many cubic yards in a dump truck for hauling limits before you order.

Round up, not down. If 8.4 tons covers your job exactly, order a hair more. Materials compact and settle, and coming up half a yard short means a second delivery fee that dwarfs the cost of a little extra stone.

Ten tons of gravel equals about 7.1 cubic yards (10 ÷ 1.4), and six cubic yards equals about 8.4 tons (6 × 1.4), using gravel's density of 1.4 tons per cubic yard (USGS, 2022).

Why Do Suppliers Price Per Ton vs Per Yard?

Suppliers price by whatever their scale or their pit measures most reliably. Quarries weigh trucks, so they quote per ton. Yards that sell screened soil or mulch often measure by volume, so they quote per cubic yard. Neither is wrong, but the U.S. construction materials market mixes both, which makes apples-to-apples comparison hard (USGS, 2022).

Here's the catch when you compare quotes. A price of $30 per ton and $40 per cubic yard are not what they look like. Convert one to match the other first. At gravel's 1.4 density, $30 per ton works out to about $42 per cubic yard ($30 × 1.4). So the "cheaper" per-ton quote is actually a touch more than the per-yard one. Always convert before you judge.

This is also why a driveway estimate can feel confusing. You measured square footage and depth, which gives you cubic yards, but the price tag says tons. Our guide on how much gravel for a driveway walks the full measurement, and then this conversion turns it into a number you can buy.

The pricing unit tells you something about the seller. Per-ton usually means closer to the pit with scale tickets. Per-yard often means a landscape yard adding a markup for screening and convenience. Knowing that helps you read a quote before you ever convert it.

Suppliers price per ton or per cubic yard based on whether they weigh or measure volume. To compare a $30/ton quote against $40/yard, convert: $30 per ton equals about $42 per cubic yard at gravel's 1.4 density (USGS, 2022).

Frequently Asked Questions

How many tons is a cubic yard of gravel?

A cubic yard of dry gravel weighs about 1.4 short tons, or roughly 2,800 pounds (USGS, 2022). Wet gravel weighs a little more. To convert any number of cubic yards to tons, just multiply by 1.4.

How do I convert cubic yards to tons for sand?

Multiply cubic yards by sand's density. Dry sand runs about 1.3 tons per cubic yard, and wet sand closer to 1.5 (USDA NRCS, 2023). So 5 cubic yards of dry sand is about 6.5 tons. Moisture is the main reason the number shifts.

How many cubic yards is 20 tons of gravel?

Twenty tons of gravel is about 14.3 cubic yards. Divide tons by gravel's density of 1.4 (20 ÷ 1.4 = 14.3). That's a large order, usually more than one dump truck, so check hauling limits before you book delivery.

Is dirt heavier than gravel per cubic yard?

Usually no. Topsoil runs about 1.1 tons per cubic yard, lighter than gravel's 1.4 (USDA NRCS, 2023). But compacted or wet fill dirt can climb to 1.3 tons or more, so it depends on the soil and how saturated it is.

Why do tons-to-yards calculators give different answers?

Because they use different densities. A gravel tons to yards calculator assumes one figure, a sand calculator another. If two tools disagree, check which density each one used. Real material varies with moisture and grain size, so any answer is an estimate until it's weighed.

Conversions get you close, but the real number depends on the exact material, its moisture, and where it's going. That's where guessing ends and a real quote begins.
