0.1 × 0.1 × 0.1 mm × 7.85×10⁻⁶
Formula
W = L × W × t × 7.85 × 10⁻⁶ [kg, dimensions in mm]
An estimate for take-off, not a design check. Structural design, member sizing and connection capacity are separate calculations made by the responsible design authority.
Assumptions and limits
- Density taken as 7,850 kg/m³, the conventional figure for structural and mild steel.
- Nominal thickness is used. Mill tolerance on plate is typically ±0.3 mm for thin plate and more for heavy plate, which moves the mass by a few percent.
- Does not include wastage or cutting allowance. Add the allowance your fabricator quotes.
