Formula for weight of steel bar D^2/162.2
For example
12×12/162.2= 0.88 kg per metre
Or there formula also be use
Unit weight of the steel × pi × d^2 / 4
For example
Unit weight of the steel is 7850
Pi value is 3.1416
Dia of the bar is 12mm
0.7850 × 3.1416 × (1.2)^2 /4 = 0.88
By using this to formula
