I'm glad I don't buy steel from you! I don't know what "tor steel" is, but no reputable materials stockist or engineering designer would mix two totally different scales like that.
If diameter is in millimetres and mass in kilogrammes, lengths should be in metres, not feet.
The question assumes what would in the real world be very poor practice both technically and commercially: use ins, lbs, ft or mm, kg, m; not a tangle of both.
0.39 kg/metre
Calculate cross sectional area of 10mm bar amd 8mm bar, then divide them and you will get the no. of bars. For Eg. - Area of 10mm bar = 78.53 sq.mm Area of 8mm bar = 50.26 sq.mm No. of 8mm bars in replacement for 10mm bar = 1.562 bars [ theoritical] In practical u'll provide 2-8mm bars.
d*d/162
0.62 kg/m is the unit weight of 10 mm dia, and you use the thumb rule for all other dia unit weight per metre = d*d/162 where- d is dia of bar/rod in mm
6.314 kg/m
0.39 kg/metre
Calculate cross sectional area of 10mm bar amd 8mm bar, then divide them and you will get the no. of bars. For Eg. - Area of 10mm bar = 78.53 sq.mm Area of 8mm bar = 50.26 sq.mm No. of 8mm bars in replacement for 10mm bar = 1.562 bars [ theoritical] In practical u'll provide 2-8mm bars.
DxD/162 this is the formula for finding unit weight of steel
Unit weight of 22mm dia reinforcement steel bar is 3 kg per metre length - Answer by m. Velsamy mobile 09884585625
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)
give me formula for weight in kg 8mm 10mm 12mm 16mm
unit wt of reinforcement bar can be obtained in kg/ meter by d*d/162.162 where d is the dia of bar The formula is based on the density of rebar 490 lb/cft
Formula for steel bar weight per meter = D2/162 where D is diameter of bar
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
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.
0.395 kg/m
Weight of MS Round Bar is calculated as ((Diameter in mm)^2)/162.
