About

Converting volume to weight requires a density coefficient specific to each material. A cubic yard of dry sand weighs roughly 2700 lbs, while the same volume of topsoil weighs approximately 2100 lbs. Applying the wrong density leads to under-ordering (project delays, extra delivery fees) or over-ordering (wasted budget, disposal costs). This calculator uses published density values from ASTM and U.S. DOT specifications to compute weight in US short tons (2000 lbs) and metric tonnes (2204.62 lbs).

Moisture content shifts density significantly. Wet sand can weigh 20% more than dry sand. Compacted gravel is denser than loose gravel by 10 - 15%. The tool provides baseline dry/loose densities. Adjust the custom density field when site conditions differ from standard assumptions. Pro tip: always confirm material density with your supplier before placing large orders.

Formulas

The conversion from volumetric measure to weight relies on the material's bulk density:

W = V × ρ2000

where W = weight in US short tons, V = volume in cubic yards (yd³), and ρ = bulk density of the material in lbs/yd³. The divisor 2000 converts pounds to US short tons.

For metric tonnes, replace the divisor:

W_metric = V × ρ2204.62

where 2204.62 lbs = 1 metric tonne. Total weight in pounds is simply W_lbs = V × ρ. For cost estimation: C = W × P, where P is the price per ton from your supplier.

Frequently Asked Questions

Moisture adds significant weight. Wet sand can have a density of 3240 lbs/yd³ versus 2700 lbs/yd³ for dry sand - a 20% increase. After rain, topsoil can gain 15 - 25% in effective weight. Always ask your supplier whether their quoted density reflects dry, damp, or saturated conditions. If material is stockpiled outdoors, assume wet density to avoid under-ordering.

Loose density measures material as dumped from a truck. Compacted density accounts for vibration or mechanical compaction that removes air voids. Compacted gravel can be 10 - 15% denser than loose gravel. If you need 10 yd³ of compacted material in place, you must order more loose material to account for volume shrinkage during compaction - typically a 1.15 to 1.25 compaction factor.

In the United States, bulk materials (gravel, sand, topsoil) are quoted in US short tons (2000 lbs). In Canada, Europe, and most other countries, metric tonnes (2204.62 lbs) are standard. Confusing the two creates a 10.2% error. Confirm the unit system with your supplier before placing an order.

The densities represent typical published averages from ASTM standards, U.S. DOT manuals, and USGS geological data for dry, loose conditions. Real-world density varies by quarry source, particle size distribution, and moisture. Actual weights can deviate ±10% from reference values. For critical projects (structural fill, road base), request a certified density test from your supplier.

Divide total weight by truck capacity. Standard dump trucks carry 12 - 14 US tons. Tandem axle trucks carry 15 - 18 US tons. Transfer trucks handle 24 - 26 US tons. Legal road weight limits vary by state and route. Over-weight fines are costly. Round up to the nearest whole truck.

Yes. Select "Custom Density" from the material dropdown and enter your material's bulk density in lbs/yd³. You can find this value on your supplier's spec sheet, ASTM test report, or USGS mineral commodity summary. If you only have density in kg/m³, multiply by 1.6856 to convert to lbs/yd³.
