About this calculator
Estimate gravel volume and approximate weight for paths and landscaping.
Bulk density varies by aggregate type and moisture, so supplier figures are better when available.
Formula
Volume = length × width × depth. Weight ≈ volume × bulk density.
Example
5m × 2m × 50mm = 0.50m³.
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.
