Formula for steel bar weight per meter = D2/162 where D is diameter of bar

Weight of MS Round Bar is calculated as ((Diameter in mm)^2)/162.

Extreme Steel bar is known as re-bar ( Reinforcing Bar), with two longitudinal and transverse ribs on the diameter of Bar.

DxD/162 this is the formula for finding unit weight of steel

=D^((D^2/162) L) D^2 = Diameter of the rod L = Length of the rod

For Mild Steel Bars: Diameter (in inches): 1/4" Weight per foot: 0.167 lb/ft Diameter (in inches): 3/8" Weight per foot: 0.376 lb/ft Diameter (in inches): 1/2" Weight per foot: 0.668 lb/ft Diameter (in inches): 5/8" Weight per foot: 1.043 lb/ft Diameter (in inches): 3/4" Weight per foot: 1.502 lb/ft Diameter (in inches): 1" Weight per foot: 2.670 lb/ft For High-Strength Deformed (HSD) Steel Bars (commonly used in construction): Diameter (in millimeters): 8 mm Weight per meter: 0.395 kg/m Diameter (in millimeters): 10 mm Weight per meter: 0.617 kg/m Diameter (in millimeters): 12 mm Weight per meter: 0.888 kg/m Diameter (in millimeters): 16 mm Weight per meter: 1.579 kg/m Diameter (in millimeters): 20 mm Weight per meter: 2.467 kg/m Diameter (in millimeters): 25 mm Weight per meter: 3.853 kg/m
