Formula: Tons = (Cubic Yards x Density in lbs/yd3) / 2000
Worked example — 15 cubic yards of gravel = 20.25 short tons
Formula
Tons = (Cubic Yards x Density in lbs/yd3) / 2000
The weight of a material depends on both its volume and density. One cubic yard equals 27 cubic feet. Material density varies widely: lightweight mulch weighs about 810 lbs per cubic yard while concrete weighs roughly 3,915 lbs per cubic yard. The result is divided by 2,000 for US short tons or 2,204.62 for metric tonnes.
Worked Examples
Example 1: Gravel for Driveway
Problem:Convert 15 cubic yards of gravel to tons.
Solution:Weight = cubic yards x density / 2000 Weight = 15 x 2700 / 2000 Weight = 40,500 / 2000 Weight = 20.25 short tons = 18.37 metric tonnes
Result:15 cubic yards of gravel = 20.25 short tons
Example 2: Topsoil Delivery
Problem:How many tons in 8 cubic yards of topsoil?
Solution:Weight = cubic yards x density / 2000 Weight = 8 x 2160 / 2000 Weight = 17,280 / 2000 Weight = 8.64 short tons = 7.84 metric tonnes
Result:8 cubic yards of topsoil = 8.64 short tons
Frequently Asked Questions
How do I convert cubic yards to tons?
To convert cubic yards to tons, multiply the number of cubic yards by the material density in pounds per cubic yard, then divide by 2,000 for US short tons. The formula is: tons = (cubic yards x density in lbs/yd3) / 2,000. For example, 10 cubic yards of gravel at 2,700 lbs per cubic yard equals 27,000 lbs, which is 13.5 short tons. The key variable is material density, which varies significantly between materials.
What is the density of common landscaping materials?
Common landscaping material densities in pounds per cubic yard are: gravel and dry sand at approximately 2,700, wet sand at 3,240, topsoil at 2,160, mulch at 810, compost at 1,080, and crushed stone at 2,700. Concrete is much heavier at approximately 3,915 lbs per cubic yard, while asphalt weighs around 3,564. These values are averages and can vary by 10-15 percent depending on moisture content, compaction, and specific material composition.
What is the difference between a short ton and a metric tonne?
A US short ton equals 2,000 pounds (907.185 kg), while a metric tonne equals 1,000 kilograms (2,204.62 pounds). A long ton (used in the UK) equals 2,240 pounds (1,016.05 kg). When ordering materials in the United States, suppliers typically quote in short tons. In most other countries, metric tonnes are standard. The difference between short tons and metric tonnes is about 10 percent, which can be significant for large orders.
How many cubic yards are in a dump truck load?
A standard dump truck holds 10 to 14 cubic yards, while a tri-axle dump truck can carry 14 to 18 cubic yards. However, the actual load is limited by weight capacity, not just volume. A tri-axle truck typically has a weight limit of about 25-28 short tons. For heavy materials like concrete or wet clay, the truck may reach its weight limit before being fully loaded by volume. Always check both volume and weight limits when ordering deliveries.
How do I work out cubic yards from a project's length, width and depth?
Measure all three dimensions in feet, multiply them for cubic feet, then divide by 27 because one cubic yard contains 27 cubic feet. A driveway 20 feet long, 10 feet wide and 6 inches deep is 20 times 10 times 0.5, which is 100 cubic feet, or 3.70 cubic yards. Convert inches of depth to feet by dividing by 12 before multiplying. Feed that cubic yard figure into the density calculation to get the tonnage you need to order.
How much does moisture content change the tonnage of a load?
Water fills the void space between particles and adds weight without adding volume, so a wet material yields more tons per cubic yard than the same material dry. Dry sand is about 2,700 pounds per cubic yard while wet sand is around 3,240, a difference of roughly 20 percent. Dry and wet clay follow the same pattern. If material has been stockpiled outdoors through rain, budget toward the wet density or you will underestimate the delivered weight.
What is the difference between bank, loose and compacted volume?
Bank volume is material still in place in the ground, loose volume is the same material after excavation when it has bulked up with air voids, and compacted volume is what remains after it is placed and rolled. Excavated soil typically swells when loosened and then shrinks below its bank volume once compacted. Trucks are billed on loose volume, but a finished trench or sub-base is specified in compacted volume, so ordering to the finished dimension alone will leave you short.
Why is mulch usually sold by the cubic yard while gravel is sold by the ton?
The unit follows what dominates the supplier's cost. Light materials such as mulch, at roughly 810 pounds per cubic yard, and compost at around 1,080 take up truck space long before they reach a weight limit, so volume is the meaningful measure. Dense materials such as gravel, limestone and concrete hit the axle weight limit first, so they are weighed over a scale and sold by the ton. Converting between the two requires the density, which is exactly what Cubic Yards to Tons Calculator applies.
How do I convert the result from US short tons to metric tonnes?
A US short ton is 2,000 pounds and a metric tonne is 1,000 kilograms, or 2,204.62 pounds. To go from short tons to tonnes, multiply by 0.907185; to go the other way, multiply tonnes by 1.10231. Alternatively divide your total pounds by 2,204.62 instead of by 2,000. The two units differ by about 10 percent, which on a 30 ton order is roughly three tons of material, so confirm which ton your supplier quotes before comparing prices.
What density should I enter for a material that is not on the list?
Use the custom option and enter the value in pounds per cubic yard, which is the unit the calculation expects. If a datasheet gives pounds per cubic foot, multiply by 27. If it gives kilograms per cubic metre, multiply by about 1.6856 to reach pounds per cubic yard. Ask the supplier for the bulk density of the specific product rather than a generic figure, since particle size, grading and moisture all shift the value by 10 to 15 percent.
