Cubic Yards of Gravel to Tons? Quick Guide

This calculator converts a volume of gravel in cubic yards to its approximate weight in tons (short tons, 2,000 lb each). You enter the volume in cubic yards and the material’s density in pounds per cubic foot, and it returns the weight in tons. The default density of 2,800 lb/yd³ (about 1.4 tons per cubic yard) is a common average for dry, loose gravel, but you can adjust it for your specific material.

Formula

The conversion relies on the relationship between volume, density, and weight. The formula used is:

Weight (tons) = (Volume (yd³) × Density (lb/ft³) × 27) / 2000

• Volume – the amount of gravel you have or need, measured in cubic yards (yd³).
• Density – the mass of gravel per unit volume, measured in pounds per cubic foot (lb/ft³). This varies with gravel type, moisture, and compaction.
• 27 – the number of cubic feet in one cubic yard (3 ft × 3 ft × 3 ft = 27 ft³).
• 2000 – the number of pounds in one short ton (U.S. ton).

The result is the weight in short tons. If you need metric tons (1,000 kg), divide the short tons by 1.10231, or use a density in kg/m³ and volume in m³ directly.

Worked Example

Using the default values: volume = 5 yd³, density = 105 lb/ft³.

1. Convert cubic yards to cubic feet: 5 yd³ × 27 = 135 ft³.
2. Calculate weight in pounds: 135 ft³ × 105 lb/ft³ = 14,175 lb.
3. Convert pounds to tons: 14,175 lb ÷ 2,000 = 7.0875 tons.

Rounded to two decimal places, the calculator shows 7.09 tons – the same result you get from the formula: (5 × 105 × 27) / 2000 = 7.0875.

Why Density Matters

Gravel is not a single uniform material. A cubic yard of loose, dry pea gravel weighs less than a cubic yard of crushed stone with fines (small particles that fill voids). Moisture adds weight too – wet gravel can be 5–10% heavier than dry gravel. The table below shows typical densities for common gravel types (values are approximate averages):

• Pea gravel (dry, loose) – about 95–105 lb/ft³ → 1.28–1.42 tons per cubic yard
• Crushed stone (1–2 inch, dry) – about 100–110 lb/ft³ → 1.35–1.49 tons per cubic yard
• Bank run gravel (with sand and clay) – about 110–120 lb/ft³ → 1.49–1.62 tons per cubic yard
• Wet gravel (any type) – add 5–10% to the dry density

If you don’t know your gravel’s exact density, the default of 105 lb/ft³ is a safe middle ground for most landscaping and construction gravel. For precise work – like structural fill or road base – ask your supplier for the specific gravity or bulk density of the material.

How to Choose the Right Density

Selecting the correct density is the difference between ordering too little (running out mid-project) and ordering too much (paying for surplus). Here’s how to narrow it down:

• Check the supplier’s spec sheet – many quarries list bulk density in lb/ft³ or kg/m³. Use that number directly.
• Use a known conversion factor – many gravel suppliers quote “1.4 tons per cubic yardâ€� as a rule of thumb. That corresponds to about 103.7 lb/ft³, close to the default.
• Adjust for moisture – if the gravel has been sitting in rain, add 5–10% to the dry density. For dry, screened gravel, use the lower end.
• When in doubt, round up – for ordering, it’s safer to use a slightly higher density (e.g., 110 lb/ft³) so you don’t come up short.

Remember that trucks and delivery services often charge by weight, not volume, so an accurate density estimate also helps you budget the delivery cost.

Common Mistakes and How to Avoid Them

Even with a simple formula, errors happen. The most frequent pitfalls:

• Mixing units – always convert everything to the same system. If you measure volume in cubic yards and density in lb/ft³, you must use the 27 factor. If you use metric (m³ and kg/m³), the conversion to tons is different: 1 metric ton = 1,000 kg.
• Using the wrong ton – a short ton (U.S.) is 2,000 lb, a long ton (U.K.) is 2,240 lb, and a metric ton is 1,000 kg (about 2,204.6 lb). This calculator uses short tons, which is standard for U.S. gravel sales.
• Confusing cubic yards with square yards – a cubic yard is a volume (3 ft × 3 ft × 3 ft), while a square yard is an area (3 ft × 3 ft). Gravel is sold by volume, so always measure in cubic yards, not square yards.
• Rounding too early – if you round the density to 100 and then round the final weight, you might be off by several percent. Keep full precision until the last step.

For a typical driveway project, a 10% error in density can mean an extra ton of gravel – enough to cover a few square feet at 4 inches deep, but it can also mean a wasted trip to the supplier.

Cost and Ordering Considerations

While this calculator gives you weight, gravel is often sold by the cubic yard, by the ton, or by the truckload. Knowing both volume and weight helps you compare prices:

• By volume – some suppliers list price per cubic yard. Multiply by your volume to get the material cost.
• By weight – others list price per ton. Multiply your calculated tons by that price.
• By truckload – a typical dump truck holds 10–14 cubic yards, which is roughly 14–19 tons depending on density. Delivery fees often depend on distance and truck size, not just weight.

Always ask whether the quoted price includes delivery and whether there’s a minimum order. For large projects, it’s common to order 10–15% extra to account for compaction and spillage.

Safety and Handling

Gravel is heavy – a single cubic yard can weigh over a ton. That has real safety implications:

• Never overload a vehicle or trailer – check the payload rating before hauling gravel. A half-cubic-yard of gravel can exceed 1,000 lb.
• Use proper lifting techniques – shoveling gravel repeatedly can strain your back. Use a wheelbarrow for moving, and take breaks.
• Wear dust protection – dry gravel creates silica dust, which is harmful if inhaled over time. A simple dust mask is sufficient for occasional projects.
• Mind the pile stability – a tall gravel pile can collapse. Keep children and pets away, and don’t dig under the pile.

For spreading gravel, consider the depth: a 4-inch layer is typical for driveways, while walkways might use 2–3 inches. To calculate the volume needed, multiply length × width × depth (in feet) and divide by 27 to get cubic yards.

Alternatives to Gravel

If you’re comparing materials, gravel isn’t the only option. Here’s a quick look at alternatives and how their densities compare:

• Crushed stone – similar density to gravel, but sharper edges lock together better for driveways.
• Sand – much lighter, about 1.2–1.4 tons per cubic yard, but shifts easily and doesn’t provide stable footing.
• Mulch – very light (0.4–0.6 tons per cubic yard), but decomposes and needs replacement.
• Recycled concrete – similar density to gravel, often cheaper, but may contain rebar or other debris.
• Pea gravel vs. crushed granite – both are gravel types, but densities vary slightly; crushed granite is often denser.

For most projects, gravel remains a cost-effective, durable choice. Its weight is a feature – it stays put – but that same weight makes accurate conversion essential for ordering and hauling.

Frequently Asked Questions

How many tons is 1 cubic yard of gravel?

With the default density of 105 lb/ft³, 1 cubic yard weighs about 1.42 tons (2,835 lb). For typical dry gravel, expect 1.3 to 1.5 tons per cubic yard. Use the calculator with your specific density for a precise number.

What is the difference between a short ton and a metric ton?

A short ton (also called a U.S. ton) equals 2,000 pounds. A metric ton equals 1,000 kilograms, which is about 2,204.6 pounds. This calculator uses short tons, so if you need metric tons, divide the result by 1.10231.

Why does wet gravel weigh more than dry gravel?

Water fills the spaces between gravel particles and adds mass. Depending on the gravel’s porosity and how much water it absorbs, wet gravel can be 5–10% heavier than dry gravel. For ordering, it’s safer to use a higher density if the gravel is damp.

How do I calculate how much gravel I need for a driveway?

Measure the length and width in feet, decide on the depth (usually 4 inches for driveways), multiply length × width × (depth in inches/12) to get cubic feet, then divide by 27 to get cubic yards. Then use this calculator to convert that volume to tons.

Can I use this calculator for other materials like sand or soil?

Yes, as long as you adjust the density. Sand is about 100–110 lb/ft³, topsoil is about 80–100 lb/ft³, and mulch is about 40–50 lb/ft³. Just enter the appropriate density, and the calculator will give the correct weight in tons.

Is it better to order gravel by volume or by weight?

It depends on how the supplier prices it. If they charge by the ton, you need the weight. If they charge by the cubic yard, you need the volume. Ordering by weight is often more accurate because it accounts for moisture and compaction, but volume is easier to measure on site. Always confirm with the supplier which unit they use.
