Estimate the weight of stainless steel products using standard geometric formulas. Select your shape, enter dimensions, and get instant results.
Use this calculator to estimate the theoretical weight of stainless steel bars, sheets, and pipes based on standard density values. All calculations use the standard density for stainless steel (7.93 g/cm³). Results are approximate — contact our sales team for exact weight certifications.
Formula:
All formulas use the standard density for stainless steel (7.93 g/cm³). Actual weights may vary slightly.
| Shape | Formula (Metric) | Variables |
|---|---|---|
| Round Bar | W = D² × 0.006165 × L | D = Diameter (mm), L = Length (m) |
| Square Bar | W = S² × 0.00785 × L | S = Side Width (mm), L = Length (m) |
| Hex Bar | W = AF² × 0.006798 × L | AF = Across Flats (mm), L = Length (m) |
| Flat / Sheet | W = W × T × 0.00785 × L | W = Width (mm), T = Thickness (mm), L = Length (m) |
| Pipe / Tube | W = (OD − WT) × WT × 0.02466 × L | OD = Outer Dia (mm), WT = Wall Thickness (mm), L = Length (m) |
