Formula
Use M = Adρ(1+w). A is area in m², d is compacted thickness converted to m, ρ is density in kg/m³, and w is the waste fraction. M is kilograms before conversion to tonnes.
Convert area and compacted thickness into material mass.

Scope and limitations
Planning estimate from your measurements and assumptions. Confirm dimensions, product coverage and local installation requirements before buying.
Inputs are checked for missing values and allowed ranges. A result outside the finite numeric range is not displayed. Rounding affects display, while the calculation uses the model’s numeric precision.
Check your units and assumptions before relying on a result. Changing a label does not convert a currency or physical unit.
