Inputs and units
Use the units shown beside each field. Replace the sample values with your measurements and the figures on the selected product packaging.
| Parameter | Example input |
|---|---|
| Length | 8 m |
| Width | 4 m |
| Layer depth | 10 cm |
| Material density | 1,600 kg/m³ |
| Waste allowance | 8 % |
Formula and assumptions
VolumeLength × Width × Layer depth / 100 × (1 + Waste allowance / 100)
Estimated massVolume × Material density / 1000
ceil = round up; floor = round down; max = the greater value. Trigonometric angles are converted from degrees to radians.
Allowance is applied before rounding to whole packages. Whole units are rounded up; displayed decimals are rounded only for readability.
Bulk density and compaction vary with moisture and the delivered material. The allowance does not model compaction; obtain the ordering conversion from your supplier.
Worked example
Sample values are examples, not product specifications. Run the calculation again with your own measurements.
