Your Result Explained: What These Numbers Mean
A cubic yard measures volume (27 cubic feet of space), while a US short ton measures weight (2,000 pounds on a scale). Because you cannot convert volume into weight without knowing how dense the material is, 1 cubic yard of cedar mulch weighs just 0.25 tons (500 lbs), 1 cubic yard of screened topsoil weighs 1.10 tons (2,200 lbs), 1 cubic yard of #57 crushed stone weighs 1.35 tons (2,700 lbs), and 1 cubic yard of concrete weighs 2.00 tons (4,000 lbs). This bi-directional converter translates cubic yards, tons, cubic feet, and retail bag counts across 16 verified materials.
Select your starting unit (Cubic Yards, US Tons, Cubic Feet, or Bags) and material to see the instant conversion into every other unit. Check the Tons Range bracket to see how rain-soaked vs. bone-dry stockpiles affect truck scale weight, and review the Coverage Area output to see how many square feet your converted quantity will cover at your target depth.
Converting 4 Cubic Yards of Crusher Run Base Stone into US Tons
A contractor calculated that a paver patio base requires 4.0 cubic yards of dense-graded crusher run (DGA), and needs to place the order with a quarry that sells stone solely by the US short ton.
- Identify input volume: 4.00 cubic yards (4 × 27 = 108.00 cubic feet).
- Look up bulk density for Crusher Run / Quarry Process (DGA): 2,800 lbs/yd³ (1.40 US short tons/yd³).
- Multiply cubic yards by pounds per cubic yard: 4.00 yd³ × 2,800 lbs/yd³ = 11,200 lbs (5,080 kg).
- Divide total pounds by 2,000 lbs/ton: 11,200 ÷ 2,000 = 5.60 US short tons (5.08 metric tonnes).
- Check moisture range (2,700–3,100 lbs/yd³): 5.40 tons (dry) to 6.20 tons (wet stockpile).
- Compute coverage at 4 inches deep: 108.00 cu ft ÷ (4 ÷ 12 ft) = 324.0 sq ft.
Result Summary: 4 cubic yards of crusher run equals 5.60 US short tons (order 5.5 to 6.0 tons at the quarry scale).
How This Is Calculated (Formulas & Measurement Guide)
When converting from Cubic Yards to Tons, the calculator multiplies your cubic yardage by the material’s bulk density in pounds per cubic yard and divides by 2,000 lbs per US short ton. When converting in reverse from Tons to Cubic Yards, it divides your tonnage by the material’s tons-per-cubic-yard factor. It then multiplies cubic yards by 27 to find cubic feet and divides by depth in feet to report square-foot coverage.
Tons = Cubic Yards × [ Material Density (lbs/yd³) ÷ 2,000 ] For #57 gravel (2,700 lbs/yd³), multiply cubic yards by 1.35. For topsoil (2,200 lbs/yd³), multiply cubic yards by 1.10.
Cubic Yards = Tons ÷ [ Material Density (lbs/yd³) ÷ 2,000 ] Dividing tons by the tons-per-yard factor converts scale weight back into loose volume.
Coverage (sq ft) = ( Cubic Yards × 324 ) ÷ Depth (inches) Every cubic yard (27 ft³) covers 324 sq ft at 1 inch deep, regardless of how heavy the material is.
How to Measure Irregular Areas & Curved Borders
Choose your known quantity and unit in the Input Unit selector (for example, "5 Cubic Yards" or "2 Tons"), pick the exact landscape material from the dropdown, and set your planned spreading depth in inches to see how much area that load will cover.
Practical Tips & Common Mistakes to Avoid
Field-Tested Planning Tips
Remember Key Multipliers: 1.4 for Stone, 1.1 for Soil, 0.3 for Mulch
When talking to a quarry or supply yard on the phone, three quick multipliers cover 90% of orders: multiply cubic yards by 1.35–1.40 for gravel/stone, multiply by 1.10 for dry screened topsoil, and multiply by 0.30 for shredded hardwood mulch.
Ask If the Yard Sells by Loader Bucket or Certified Scale
Landscape supply yards typically sell mulch, compost, and topsoil by the cubic-yard loader scoop (so rain moisture doesn’t cost you extra money), whereas stone quarries weigh dump trucks empty and full on a certified scale and bill per ton.
Watch Out for Rain-Soaked Stockpiles When Buying by the Ton
If you buy topsoil or sand across a truck scale right after three days of heavy rain, water trapped in the pore spaces can increase bulk weight by 10% to 15%—meaning 1 ton on the scale gives you fewer cubic feet of actual coverage.
Use Custom Density If Your Quarry Provides a Spec Sheet
Local geology matters: porous Florida oolitic limestone can weigh 2,350 lbs/yd³ (1.18 tons/yd³), while dense Pennsylvania diabase trap rock can hit 2,950 lbs/yd³ (1.48 tons/yd³). Expand the Advanced Options to enter your quarry’s exact lbs/yd³ figure.
Common Ordering & Installation Mistakes
Mistake Assuming 1 cubic yard always equals 1 ton
Recommended Fix: No common landscape material weighs exactly 2,000 lbs per cubic yard except bone-dry sandy loam. Assuming 1 yard = 1 ton for gravel (which is 1.35–1.40 tons/yd³) causes a 35% to 40% error in your order or trailer payload.
Mistake Confusing US Short Tons (2,000 lbs) with Metric Tonnes (2,204.6 lbs)
Recommended Fix: All US quarries and DOT scales use the 2,000-lb US short ton. Our calculator reports both US short tons and metric tonnes (t) so international specs are never mixed up.
Mistake Forgetting that coverage per ton changes with material density
Recommended Fix: While 1 cubic yard of any material always covers 108 sq ft at 3 inches deep, 1 ton of lightweight lava rock covers 166 sq ft at 3 inches deep whereas 1 ton of heavy crusher run covers only 77 sq ft at 3 inches deep.
Mistake Overloading a 1-ton dump trailer with 5 cubic yards of stone
Recommended Fix: Five cubic yards of crushed stone weighs 6.75 to 7.0 tons (13,500–14,000 lbs)—which requires a heavy-duty 14,000-lb GVWR tandem dual-axle trailer and a 3/4-ton or 1-ton tow vehicle.

Frequently Asked Questions (Yards to Tons Calculator)
How many tons is 1 cubic yard of gravel?
One cubic yard of standard #57 crushed stone (3/4" clean limestone or granite) weighs 2,700 lbs, or 1.35 US short tons. Dense-graded driveway crusher run weighs 2,800 lbs (1.40 tons) per cubic yard, and washed 3/8" pea gravel weighs 2,600 lbs (1.30 tons) per cubic yard.
How many cubic yards are in 1 ton of gravel, sand, or topsoil?
Divide 1 by the tons-per-cubic-yard density: 1 ton of #57 gravel (1.35 tons/yd³) equals 0.74 cubic yards (20.0 cubic feet); 1 ton of crusher run (1.40 tons/yd³) equals 0.71 cubic yards (19.3 cubic feet); 1 ton of masonry sand or pea gravel (1.30 tons/yd³) equals 0.77 cubic yards (20.8 cubic feet); and 1 ton of screened topsoil (1.10 tons/yd³) equals 0.91 cubic yards (24.5 cubic feet).
How many tons is 1 cubic yard of topsoil or fill dirt?
Dry-to-field-moist screened loam topsoil averages 2,200 lbs (1.10 US short tons) per cubic yard. Heavy, damp clay-loam fill dirt averages 2,500 lbs (1.25 tons) per cubic yard, while a 50/50 topsoil-compost garden blend weighs about 1,600 lbs (0.80 tons) per cubic yard.
How many tons is 1 cubic yard of mulch?
Seasoned shredded hardwood mulch weighs about 600 lbs (0.30 tons) per cubic yard, cedar or pine bark mulch weighs about 500 lbs (0.25 tons) per cubic yard, and fresh damp arborist wood chips weigh around 800 lbs (0.40 tons) per cubic yard.
Why do quarries sell stone by the ton instead of by the cubic yard?
Front-end loader buckets can vary by 10% to 15% depending on how high the operator heaps the scoop and how much air void space sits between loose rocks. Weighing the dump truck on a state-certified scale before and after loading guarantees an exact, repeatable measurement down to 20 lbs.
