Estimate material weight from project dimensions, depth, and density. This tonnage calculator converts area and thickness into cubic feet, cubic yards, pounds, and U.S. tons so you can plan gravel, crushed stone, road base, sand, fill, and similar bulk materials with fewer ordering mistakes.

In U.S. construction estimating, one cubic yard equals 27 cubic feet, and one short ton equals 2,000 pounds. That means the core formula is simple: tons = cubic yards × 27 × density in lb/ft³ ÷ 2000.
Tonnage estimates depend on bulk density, not just volume. Supplier values are always better than generic numbers, but the lookup table below works well for planning and bid-stage estimating.
| Material | Typical Density (lb/ft³) | Approx. Tons per Cubic Yard | Planning Notes |
|---|---|---|---|
| Pea Gravel | 100 | 1.35 | Good for drainage and decorative surfacing. |
| Gravel | 105 | 1.42 | Common planning value for mixed gravel products. |
| Sand | 106 | 1.43 | Moisture can shift delivered weight noticeably. |
| Road Base | 120 | 1.62 | Compaction and fines content matter. |
| Fill Dirt | 95 | 1.28 | Varies widely by moisture and soil type. |
| Crushed Stone | 145 | 1.96 | Heavy planning value often used for angular aggregate. |
| Rip Rap | 140 | 1.89 | Void space and rock size can change field yield. |
If you also need volume-focused estimates, use the gravel calculator, crushed stone calculator, or road base calculator for more material-specific planning.
Suppliers often sell aggregate by the ton, while field measurements are usually taken in feet and inches. That mismatch is where ordering errors happen, especially on driveways, trenches, subbase layers, and drainage zones.
A volume-only estimate may look correct and still miss the delivered weight if the material is denser, wetter, or more compactable than expected. Tonnage is what affects haul planning, truck count, invoice totals, and equipment staging.
For driveway work, trench backfill, and base preparation, related tools such as the base material calculator, backfill calculator, and drain rock calculator can help you compare alternate materials and layer thicknesses.
Area: 24 ft × 12 ft
Depth: 4 in
Material: Road base at 120 lb/ft³
Waste: 8%
This is the kind of job where a rounded order of 6.25 tons may be more practical than ordering exactly 6.22 tons, depending on supplier increments and grading conditions.
Area: Circle, 16 ft diameter
Depth: 3 in
Material: Pea gravel at 100 lb/ft³
Waste: 5%
Decorative work often needs a little extra because irregular edges and planting cutouts rarely match a perfect circle in the field.
Area: Triangle, 18 ft base × 10 ft height
Depth: 6 in
Material: Fill dirt at 95 lb/ft³
Waste: 10%
On fill work, moisture and compaction often shift the delivered quantity more than the raw geometry does, so field verification matters.
This is the biggest source of error. The same cubic yard count can produce very different tonnage results if you switch from decorative gravel to dense crushed stone or wet sand.
Some suppliers quote loose tons, while plans may call for a compacted finished depth. If the spec is for compacted placement, account for compaction before ordering.
Edge feathering, subgrade irregularity, and cleanup all consume material. A zero-waste estimate is usually too tight for real field conditions.
Legal payload varies by truck type, route, moisture, and local hauling practice. Confirm capacity before translating tons into delivery loads.
Bulk aggregate is commonly sold by U.S. short ton in the United States. A short ton equals 2,000 pounds, which is different from a long ton at 2,240 pounds and a metric tonne at 2,204.62 pounds.
If you are building a gravel driveway or base section, material quantity is only one part of the plan. Cost, hauling, excavation, and section thickness matter too, so it can help to compare results with the gravel driveway cost calculator, excavation cost calculator, and fill dirt calculator.
Ask your supplier for the material’s delivered bulk density, the minimum billable load, and the truck’s practical payload. Those three numbers usually matter more than a generic online density table.
Multiply cubic yards by 27 to convert to cubic feet, multiply by density in lb/ft³, then divide by 2,000 to convert pounds to U.S. short tons. If you already know tons per cubic yard for the material, you can multiply cubic yards directly by that value.
In U.S. construction, a ton usually means a short ton of 2,000 pounds. A metric tonne is 2,204.62 pounds, and a long ton is 2,240 pounds. This calculator uses the U.S. short ton because that is the standard purchasing unit for most American bulk material suppliers.
Yes, but density matters even more for soils than for stone. Moisture content, organic content, and degree of compaction can shift weight noticeably, so use actual supplier or geotechnical values whenever possible.
For many residential and light site jobs, 5% to 10% is a reasonable planning range. Irregular site grades, poorly defined edges, and hand spreading can justify a larger allowance.
Supplier values may reflect actual quarry gradation, moisture, and local handling conditions. Generic tables are planning tools only, so a quarry or yard ticket value should take priority when you are placing an order.
No. Engineered fill, bearing soils, retaining systems, and permitted structural work require project-specific design and verification. This tool is for estimating material quantity, not replacing geotechnical or structural design documents.
