Gravel volume

- Estimated weight
- lb
One cubic yard is 27 cubic feet. One US short ton is 2,000 pounds.
Weight is an estimate based on your density input. Aggregate type, moisture, compaction, and supplier measurements affect ordering quantities. No compaction factor, base-depth recommendation, or site engineering is assumed.
How to Use This Calculator
Estimate aggregate volume and weight using your material’s bulk density.
Decimals and fractions accepted for dimensions. Unmarked values use the labeled unit; explicit feet/inches are converted. For example, 10' 6 1/4" is an explicit length; 10.6 means 10.6 of the labeled unit. Rates, prices, counts and areas use numbers only.
Inputs and where to find them
Length (ft). Measure the length of the rectangular area receiving aggregate. For separate or irregular areas, calculate smaller rectangular sections and add their quantities. Keep the dimensions on the same basis as the intended aggregate layer.
Width (ft). Measure across the aggregate area at right angles to its length. The length and width describe the area being filled, not a truck bed or pile. A changing width should be divided into separate sections.
Depth (in). Enter the depth of the aggregate layer you are estimating. Decide whether that is a loose placed depth or another specified condition, and use a density on the same basis. The calculator does not add material for compaction or waste.
Bulk density (lb / cubic ft). Bulk density is the weight of a cubic foot of the aggregate, including the spaces between particles. Obtain a suitable figure from the supplier for the material and moisture condition. Loose and compacted densities can differ, so a generic rock density is not a reliable substitute.
Results, example and assumptions
Cubic feet and cubic yards describe the same aggregate volume. Pounds and US short tons convert that volume using your density; a short ton is 2,000 pounds. There is no separate waste or compaction allowance. Confirm how the supplier measures and sells the material before placing an order.
Cubic feet = length (ft) × width (ft) × depth (in) ÷ 12.
Cubic yards = cubic feet ÷ 27.
Pounds = cubic feet × density (lb/ft³).
US short tons = pounds ÷ 2,000.
Worked example: 10 × 10 ft at 4 inches deep is 33.3333 ft³ or 1.2346 yd³. Using an illustrative, user-entered density of 100 lb/ft³ gives 3,333.3333 lb or 1.6667 US short tons. That density is an arithmetic example, not a recommendation for your aggregate.
