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 |
|---|---|
| Column diameter | 30 cm |
| Height | 2.5 m |
| Number of pieces | 4 |
| Waste allowance | 5 % |
Formula and assumptions
Volumeπ × (Column diameter / 200)² × Height × Number of pieces × (1 + Waste allowance / 100)
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.
Geometry and material quantities do not determine load capacity or reinforcement design. Use dimensions specified in the project.
Worked example
Sample values are examples, not product specifications. Run the calculation again with your own measurements.
