How it works

  1. 1Per meter = 0.00617 × 12² = 0.888 kg/m
  2. 2Total = 0.888 × 1 m = 0.888 kg
  3. 3Coefficients from the 7.85 g/cm³ industry shorthand

Industry shorthand formulas (density 7.85 g/cm³): round bar W = 0.00617 × d²; pipe W = 0.02466 × wall × (OD − wall); plate W = 7.85 × thickness(mm) × width(m) per meter of length. Example: Φ12 rebar ≈ 0.888 kg/m; Φ159×5 pipe ≈ 18.99 kg/m.

Galvanized steel multiplies the result by ~1.06; stainless steel (density ≈ 7.93) is slightly heavier. These are theoretical values for estimation — use the weighed weight for settlement.

Rebar trade convention: keep 3 decimals for Φ12 and below and Φ28 and above, 2 decimals for Φ14-Φ25 (e.g. 8 → 0.395 kg/m, 25 → 3.85 kg/m).
