A general volume calculator for soil, debris, containers and bulk material estimates.
Results use your measurements and editable assumptions. Verify product coverage, density, waste and order rounding with the supplier before purchasing.
Cubic yards = length × width × depth in feet ÷ 27.
BuildCalc converts measurements to a consistent internal unit, applies your project geometry and only then adds the selected waste allowance. Packaging quantities are rounded up because partial bags, blocks or boxes usually cannot be ordered.
This general volume calculator is useful before moving to a material-specific estimator. Keep all dimensions in the correct units, divide irregular spaces into non-overlapping rectangles, and remember that geometric volume does not account for compaction, bulking or container voids.
An area 18 ft long by 9 ft wide at a depth of 6 in contains 81 cubic feet. Dividing by 27 converts the result to exactly 3 cubic yards.
There are 27 cubic feet in one cubic yard because one yard equals three feet in each of three dimensions: 3 × 3 × 3.
Not always. Loose fill, compaction, moisture, settling and supplier rounding can make the delivered quantity differ from geometric volume.
