2.9876 kg/m is the weight of steel bar of 22 mm dia..and you use formula for other bars as d*d/162
Where d is a diameter of bar in mm.
Formula for steel bar weight per meter = D2/162 where D is diameter of bar
volume of steel multiplied by7850= wt of steel in kgs. Please note that wt of 1 Cum steel is 7850 kg Volume of steel bar can be calculated = cross-sectional area of bar X length cross-sectional area of Bar= pie x d X d/4 (where d is diameter of bar)
0.395 kg/m
Weight per metre length= 0.559 kg

Unit weight of 22mm dia reinforcement steel bar is 3 kg per metre length - Answer by m. Velsamy mobile 09884585625
22mm diameter deformed bars unit weight kilogram per meter
Formula for steel bar weight per meter = D2/162 where D is diameter of bar
volume of steel multiplied by7850= wt of steel in kgs. Please note that wt of 1 Cum steel is 7850 kg Volume of steel bar can be calculated = cross-sectional area of bar X length cross-sectional area of Bar= pie x d X d/4 (where d is diameter of bar)
0.395 kg/m
DxD/162 this is the formula for finding unit weight of steel
0.39 kg/metre
