About this calculator
Estimate sand volume and approximate tonnes from bulk density.
Density varies by sand type and moisture.
Formula
Volume = length × width × depth. Weight ≈ volume × bulk density.
Example
5m × 3m × 50mm = 0.75m³.
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.
