About this calculator
Estimate topsoil volume in cubic metres and litres.
Allow for settlement and supplier recommendations where needed.
Formula
Volume = length × width × depth. Litres = cubic metres × 1,000.
Example
5m × 3m × 100mm = 1.5m³.
Accuracy
NUMTX shows the assumptions next to the calculation so you can replace defaults with values that match your situation. For measurements, supplier rates, fees, interest, tax or regulated work, confirm important figures with the appropriate official or professional source.
