Tonnage Calculator

The Tonnage Calculator converts the dimensions of a construction or landscaping area into the exact weight of bulk material you need to order — so you're not guessing at the yard or overpaying for excess. Select your area shape (rectangular or circular), enter your length/width or diameter, set the depth, and choose a material type (crushed stone, drain rock, sand, asphalt, and more). You'll get the total tons required, plus cubic yards, cubic feet, and total area covered.

Frequently Asked Questions

What is a tonnage in construction materials?

Tonnage refers to the weight in tons of construction materials like aggregates, gravel, sand, and crushed stone. It's the standard unit suppliers use for pricing and ordering bulk materials.

How do I convert yards to tons for gravel?

To convert cubic yards to tons, multiply the cubic yards by the material's density. For example, gravel typically weighs 1.3-1.7 tons per cubic yard depending on the type and compaction.

What area will 1 ton of gravel cover?

One ton of gravel typically covers approximately 100-120 square feet at 2 inches deep, or 50-60 square feet at 4 inches deep, depending on the gravel type and size.

How many yards is a ton of crushed stone?

One ton of crushed stone equals approximately 0.6 to 0.7 cubic yards. The exact conversion depends on the stone type, size, and compaction level.

How accurate is this tonnage calculator?

This calculator provides estimates based on standard material densities. Actual tonnage may vary by 5-10% due to material variations, moisture content, and compaction differences.

Should I order extra material beyond the calculated amount?

Yes, it's recommended to order 5-10% extra material to account for compaction, waste, and minor calculation variations. This ensures you have enough material to complete your project.

What's the difference between cubic feet and cubic yards?

There are 27 cubic feet in one cubic yard (3 × 3 × 3 = 27). Cubic yards are commonly used for larger quantities of bulk materials, while cubic feet are used for smaller amounts.

How deep should I spread aggregate materials?

Typical depths are 2-4 inches for pathways and driveways, 4-6 inches for parking areas, and 6-8 inches for heavy traffic areas. Deeper applications provide better stability and drainage.
