Review the method below for assumptions and conventions.

How to use this tool

  1. Enter area to cover, soil depth, bulk density.
  2. Select Calculate to view the result.
  3. Check the method and assumptions below before using the result.

The method, explained

Volume = area × depth/100. Mass = volume × bulk density.

A WORKED EXAMPLE

Using area to cover = 20 m², soil depth = 15 cm, bulk density = 1200 kg/m³, the result is 3 m³. Change these example inputs to match your task; use the method above to check each step.

What to keep in mind

A material-quantity estimate, not a structural design or building-code check. Confirm site measurements, supplier coverage and waste before ordering.

Common questions

Which inputs does this calculation need?

Estimate soil volume and mass for an even layer. Enter area to cover in m², soil depth in cm, bulk density in kg/m³. The filled example is editable and is not a saved personal record.

How should I interpret the result?

A material-quantity estimate, not a structural design or building-code check. Confirm site measurements, supplier coverage and waste before ordering.
