How the weight is calculated
Area = π ÷ 4 × 43² = 1,452.2 mm². Weight per metre = area × 7850 kg/m³ = 1,452.2 × 10⁻⁶ m² × 7850 = 11.400 kg/m. In US units: 1.693² × 2.67 = 7.661 lb/ft.
Deformed bars and TMT bars are sold by nominal diameter and nominal mass; the ribs are already allowed for, and standards accept a small mass tolerance per bar. See the rebar weight formula guide.
