Measure twice.
Order once.
For a rectangle, multiply length × width × depth with all dimensions in feet. Divide cubic feet by 27 to get cubic yards. For a circle, area is π × radius².
Order volume = measured volume × (1 + extra percentage ÷ 100). Weight = order volume in cubic yards × density in US tons per cubic yard. One US short ton is 2,000 pounds; it is different from a metric tonne.

How much does one cubic yard of gravel weigh?
There is no single weight for every gravel product. This calculator starts at 1.4 US tons per cubic yard for crushed gravel as a planning assumption. Ask your supplier for the actual bulk density, then change the density field.
Does this account for compaction?
The extra percentage is an ordering allowance, not an engineered compaction factor. If your depth describes the finished compacted layer, ask the supplier or contractor how much loose material is required to achieve it.
How do I measure an irregular area?
Break it into rectangles and circles and calculate each section separately. Avoid counting overlapping sections twice. For varying depths, take several measurements and use a representative average, or calculate each depth zone separately.
