6.118 kg/m

Total weight

36.7 kg

Density: 7.85 kg/dm³

Formula and example

Cross-section area A = (√3 / 2) s² (mm). Weight per metre = A × density ÷ 1000, with the density in kg/dm³.

(√3 / 2) s²

Example: 20 mm in steel weighs 2.72 kg/m, so a 6 m length weighs 16.32 kg.

Carbon steel 7.85 kg/dm³, stainless steel (AISI 304) 7.93 kg/dm³, aluminium 2.70 kg/dm³. Delivered weights can differ from calculated ones within the mass tolerance of the product standard.
