Calculate the weight of flat sheet metal blanks and multi-part jobs. Supports mild steel, stainless steel, aluminium, galvanised, and zinc anneal.
Select a material and enter your blank dimensions to calculate weight. Add multiple parts to get a total job weight.
| Part Name | W (mm) | L (mm) | T (mm) | Qty |
|---|
Standard densities used for all calculations:
| Material | Density (kg/m³) |
|---|---|
| Mild Steel (CR/HR) | 7,850 |
| Galvanised Steel | 7,850 |
| Zinc Anneal | 7,850 |
| Stainless 304 / 316 | 8,000 |
| Aluminium (all grades) | 2,710 |
| Copper | 8,960 |
| Brass | 8,500 |
Weight is calculated from the volume of the blank multiplied by material density:
W = (L × W × T) ÷ 1,000,000,000 × ρ × Qty
Where L, W, T are in mm and ρ (density) is in kg/m³. The division by 10⁹ converts mm³ to m³.
Use the Multi-Part mode to tally up a full cutting list. Each part can have its own thickness — useful for jobs mixing different gauges.
For folded parts, use the flat blank dimensions (before bending), not the finished part dimensions.
