MihsabaHow to use
Estimate sand volume and approximate mass from area, depth, bulk density and allowance.
- Enter Area (m²).
- Enter Depth (cm).
- Enter Bulk density (t/m³).
- Enter Allowance (%).
- Calculate, then review the assumptions before purchasing.
How it is calculated
Example
Thirty square metres at 5 cm depth plus 10% allowance equals 1.65 m³; at 1.6 t/m³ it is about 2.64 tonnes.
Important notes
Dry, wet and compacted sand can differ in density and volume. Use the supplier specification and do not treat the calculated mass as an exact delivery weight without measurement.
Worked examples and interpreting results
Thirty square metres at 5 cm depth plus 10% allowance equals 1.65 m³; at 1.6 t/m³ it is about 2.64 tonnes.
| Case | Calculation | Result |
|---|---|---|
| Volume | 30 × 0.05 × 1.10 | 1.65 m³ |
| Mass | 1.65 × 1.6 | 2.64 |
How to check the result
Dry, wet and compacted sand can differ in density and volume. Use the supplier specification and do not treat the calculated mass as an exact delivery weight without measurement.
Frequently asked questions
Does wet sand differ from dry sand?
Yes. Moisture and compaction change bulk density, so use a supplier value for the condition being delivered.
Should I include waste?
Include an allowance when cuts, breakage or layout losses are expected. Use a percentage that fits your project rather than assuming one fixed rate.
Do the units need to match?
Yes. The calculator assumes the units stated beside each field, so convert measurements first when your source uses different units.
