Weight of steel bars= Cross sectional area of steel bar x Length of steel bar x Density of steel bar. That means, W = A x L x ρ Where, A = Area = πD²/4 π (pi) = 3.14 D = Diameter of steel bar in millimeter L = Length of steel bar in meter ρ (Rho) = Density of steel bar = 7850 kg/m³ Therefore, W = 3.14 x D²/4 x L x 7850 But there are two conflicting unit in the formula. Those are millimeter for D and m for ρ (Rho). We have to convert either D or ρ to same unit. Let’s convert D from millimeter to meter. 1 millimeter = 1/1000 meter Lets implement this to the formula, W= 3.14 x D²/(4x1000x1000) x L x 7850 = D²L/162 Using this formula we can calculate the weight of steel bars. Example How to calculate the weight of 100 meter long 16mm ø bar? In this example, D= 16mm L = 100 m So, W = D²L/162 = 16² x 100/162 = 158 kg (approx) Note: W = D²L/162 IS ONLY FOR ROUND BAR…
