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)
unit weight of that steel bar multiplied by its total length
Formula for steel bar weight per meter = D2/162 where D is diameter of bar
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 calculation of steel round bar > Area (square metres) of cross section * 7850 = kilograms per metre length. For other lengths, multiply answer by length in metres.
to calculate the weight of diffrent dia bars is d2/162 D=dia of bar , and multiply into 2 times then divide it by 162
Calculate the length of steel you are going to use the building and muliply the length with unit weight of the steel.ex: 12 m 25mm steel weight is12 x 3.85 =46.2 kg3.85 kg/m is the unit weight of 25mm bar
Formula for steel bar weight per meter = D2/162 where D is diameter of bar
For surface area of steel bar= pi*diameter*length For cross-sectional area of steel bar= pi (dia)^2/4
If the bar is circular then it is: pi*radius square
DxD/162 this is the formula for finding unit weight of steel
d*d/162
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 calculation of steel round bar > Area (square metres) of cross section * 7850 = kilograms per metre length. For other lengths, multiply answer by length in metres.
weight and length of steel bar ~6
to calculate the weight of diffrent dia bars is d2/162 D=dia of bar , and multiply into 2 times then divide it by 162
AREA*THICKNESS(length)*7.85 pi*r2*t*7.85 - in mm
Convert all the measurements to compatible units, for example, decimeters. Calculate the volume. Look up the density of steel, then use the formula: mass = density x volume If you converted to SI units, that will give you the mass (not the weight) in kilograms. To actually convert to weight, multiply by 9.8 (assuming normal Earth gravity); this will give you the weight in newton.
Calculate the length of steel you are going to use the building and muliply the length with unit weight of the steel.ex: 12 m 25mm steel weight is12 x 3.85 =46.2 kg3.85 kg/m is the unit weight of 25mm bar
