Stockpile Volume Estimator
Cone and frustum stockpile volumes, with optional conversion to tonnes using a material density.
Cone V = πr²h ÷ 3 · frustum V = πh(R² + Rr + r²) ÷ 3. Densities are typical loose bulk densities; moisture and compaction change them, so confirm with your supplier or a weighbridge.
Indicative result, not a survey. Only a plan prepared and signed by a registered surveyor is valid for title, legal or design purposes.

How it works
Measure the base by pacing or taping round it, and the height with a level or a measured pole. Irregular stockpiles are better measured by drone or terrestrial survey.
