Cubic Yards to Tons Calculator: Aggregate & Soil Weight Estimator
Use this cubic yards to tons to convert bulk material volume from cubic yards into total weight in tons and pounds. Quarries and aggregate yards sell heavy gravel, sand, and crushed road base across certified scales by the ton rather than by the scoop. Use this calculator to verify truck payload limits and get accurate delivery quotes.
Order 8 tons from the quarry (~14,700 lbs), or approx 295 bags (50-lb each).

We believe all home improvement estimates should be transparent and verifiable. Below is the exact math running in this browser tool:
-
Tonnage Weight Formula:
Total Tons = Cubic Yards × Bulk Density (Tons / Cu Yd) × (1 + (Waste % ÷ 100))Multiplies cubic yard displacement by bulk specific density with an adjustable compaction margin. -
Pounds & Metric Tonnes Conversion:
Pounds = Tons × 2,000 | Metric Tonnes = Tons × 0.907185Standard conversion factors between US short tons (2,000 lbs) and international metric tonnes (1,000 kg). -
Truckload Capacity Standard:
Standard Single-Axle Dump = ~5 Tons | Tandem-Axle Dump = ~14 TonsStandard commercial hauler payload capacities before state highway axle weight restrictions apply.
Note: All default assumptions (waste %, coverage rates, container yields) can be adjusted directly in the input fields above to match your project specifications.
How to Determine Bulk Volume and Select Aggregate Density
- Calculate total excavation volume: Measure length, width, and depth in feet, multiply them together, and divide by 27 to find cubic yards.
- Identify your exact quarry aggregate type: Clean washed rock has more void space than dense-graded road base with fines.
- Select aggregate bulk density: Crushed stone typically weighs 1.4 tons/yd³, clean river gravel weighs 1.3 to 1.35 tons/yd³, and dry sand weighs 1.35 tons/yd³.
- Account for moisture content: Saturated sand or soaking wet topsoil can add 200 to 400 pounds per cubic yard after heavy rain.
- Add compaction allowance: Road base aggregate compacted with a plate compactor loses 10% to 15% volume, requiring extra tonnage.
- Check residential delivery constraints: A fully loaded tandem dump truck weighs over 50,000 pounds gross and may crack residential concrete driveways.
How the Cubic Yards to Tons Calculation Works (Worked Example)
Consider ordering 3/4-inch crushed limestone road base for a 6 cubic yard patio sub-base with a 1.4 tons/yd³ bulk density and 5% compaction allowance:
- 1. Base Volume Required: 6.0 cubic yards.
- 2. Bulk Density of 3/4" Crushed Limestone: 1.40 tons per cubic yard (2,800 lbs/yd³).
- 3. Base Tonnage: 6.0 cu yds × 1.40 tons/yd³ = 8.40 tons.
- 4. Apply 5% Compaction & Spreading Margin: 8.40 × 1.05 = 8.82 tons.
- 5. Total Weight in Pounds: 8.82 tons × 2,000 lbs/ton = 17,640 pounds.
- 6. Metric Weight Equivalent: 8.82 × 0.9072 = 8.00 metric tonnes.
- 7. Commercial Delivery Logistics: Order 9.0 tons from the quarry, which fits comfortably in a single tri-axle or large tandem dump truck delivery.

| Material Type | Tons per Cu Yd | Pounds per Cu Yd | Lbs per Cu Ft | Compaction Behavior |
|---|---|---|---|---|
| Crushed Stone (3/4" clean) | 1.40 tons | 2,800 lbs | 104 lbs | Minimal (2%–5%) |
| Crushed Road Base (with stone dust) | 1.50 tons | 3,000 lbs | 111 lbs | High (10%–15%) |
| Pea Gravel / River Rock | 1.35 tons | 2,700 lbs | 100 lbs | Low (3%–6%) |
| Concrete Sand (washed coarse) | 1.40 tons | 2,800 lbs | 104 lbs | Moderate (5%–8%) |
| Screened Topsoil (dry to damp) | 1.10 tons | 2,200 lbs | 81 lbs | High (10%–15% settling) |
| Hardwood Bark Mulch | 0.40 tons | 800 lbs | 30 lbs | High (15% settling) |
Frequently Asked Questions About Cubic Yards to Tons Calculator
Why do quarries sell gravel and sand by the ton instead of the cubic yard?
Quarries weigh haul trucks on certified drive-on platform scales before and after loading. Because front-loader buckets vary and loose material has variable air pockets, selling by net scale weight in tons is legally certified and prevents under-scooping disputes.
How many cubic yards are in 1 ton of gravel?
For standard crushed gravel weighing 1.4 tons per cubic yard, 1 ton equals approximately 0.71 cubic yards (approx 19.3 cubic feet). For lighter topsoil (~1.1 tons/yd³), 1 ton equals about 0.91 cubic yards.
How much weight can a standard residential dump truck carry?
A standard single-axle dump truck carries 5 to 6 tons of gravel. A tandem-axle truck handles 12 to 14 tons, and a commercial tri-axle dump truck transports up to 18 to 22 tons depending on local highway gross vehicle weight limits.
Does rain make gravel or soil heavier at the quarry?
Yes. While gravel sheds water quickly, damp or saturated sand and organic topsoil absorb significant moisture, increasing scale weight by 10% to 20% without giving you any extra dry cubic volume.
How many 50-lb bags equal one ton of aggregate?
One US short ton is 2,000 pounds. Dividing 2,000 by 50 equals exactly 40 fifty-pound bags per ton.
