How to use the Gravel Calculator

Estimate gravel volume in cubic yards and approximate weight based on area, depth, and bulk density.

Calculation formula

Cubic yards = length (ft) × width (ft) × depth (in) ÷ 12 ÷ 27. Estimated US tons = cubic yards × bulk density.

Recommended steps

1. Enter values using the units shown beside each field.
2. Review whether the example assumptions match your situation.
3. Run the calculator and compare the key metrics.
4. Use the source data or official rates when precision matters.

Known limitations

Density depends on gravel type and moisture. This calculator estimates uncompacted volume; account for compaction and waste separately.
