0.395 kgs = unit wt of 8 mm dia rebar There is another way of calculating the specific weight (or unit weight) of a rebar. Especially for those who are interested of rebars less than 10mm of dia. the way is to calculate it mathematically knowing that the density of steel rebars is 7851 Kg/m3. 8mm rebar ==>
Unit weight [Kg/m] = Cross-Sectional Area [m2] x Density [kg/m3]
= (Pi)x(radios)2 x 7851 kg/m3 = 0.395 Kg/m Good luck !!
Use this equation..
0.0062*(Diameter Square) = Wt in Kg of steel/meter Length.
For 14mm steel
0.0062*14*14 = 1.2152 Kg per running meter

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
8mm rebar weighs 0.395kg/m
Unit weight of 36mm rebar is 7.99 kg per meter

You have to find a chart that will indicate the weight per unit of measure for the appropriate rebar size. Than take that and multiply it by the the length of the rebar. For example, a #4 rebar weighs 0.668 lbs/ft. If you have 5 @ 20-00 pieces that is 0.668 X 20 X 5 = 67 lbs. Charts are available throughout the web or at CRSI.org.
