Steel Weight Formula
Steel weight is calculated using the material’s volume and density.
Steel Weight = Volume × Density
Where:
- Volume is calculated from the dimensions of the selected steel shape.
- Density of carbon steel is approximately 7,850 kg/m³.
The calculator performs these calculations automatically and converts the result into your preferred unit.
Steel Density Explained
Steel density is one of the most important values used in weight calculations.
| Material | Approximate Density |
|---|---|
| Carbon Steel | 7,850 kg/m³ |
| Stainless Steel | 7,900–8,000 kg/m³ |
| Cast Steel | 7,700–7,900 kg/m³ |
| Alloy Steel | Varies by composition |
Using the correct density improves calculation accuracy, particularly when working with specialty steels.
