Method notes 4 notes
  • Weight = density × cross-section area × length. Mild / low-carbon steel (A36/1018) density = 7.85 g/cm³.
  • Cross-section of a round bar: A = π/4 · d².
  • Weight-per-length is independent of the length you enter.
  • Nominal density — real alloy weight varies slightly with composition and temper.
