Usually 6mm, 8mm,10mm,12mm, 16mm, 20mm, 25mm, 32mm, 40mm dia size of reinforced steel bar used in construction, in this bars 6mm & 8mm are called as plain bar and 12mm, 16mm, 20mm, 25mm, 32mm, 40mm bars are called as rebar (or) Torsion bar , usually standard length of one reinforced steel bar is 9m or 12m.

**Plain bar:- ** The steel bar is don’t have rip which is called as plain bar

**Torsion / Rebar:- **The steel bar having a rip which is called as torsion or rebar

__Formula to find weight of reinforced steel rod / ____unit weight of steel bars.__

** Formula = D²/162, **D-Diameter of steel bar

#### Unit Weight calculation of Steel bar @ 1m Length

- Unit Weight of 6 mm Steel bar = 6² /162 = 0.22 kg/m
- Unit Weight of 8 mm Steel bar = 8² /162 = 0.395 kg/m
- Unit Weight of 10 mm Steel bar = 10² /162 = 0.617 kg/m
- Unit Weight of 12 mm Steel bar = 12² /162 = 0.889 kg/m
- Unit Weight of 16 mm Steel bar = 16² /162 = 1.580 kg/m
- Unit Weight of 20 mm Steel bar = 20² /162 = 2.469 kg/m
- Unit Weight of 25 mm Steel bar = 25² /162 = 3.858 kg/m
- Unit Weight of 32 mm Steel bar = 32² /162 = 6.321 kg/m
- Unit Weight of 40 mm Steel bar = 40² /162 = 9.877 kg/m

Standard length of one reinforced steel bar is 9m or 12m, so
