The unit weight of 16 mm reinforcement is 1.58 kg/m
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 !!

16mm dia weight for running feet
The unit weight of a 16mm steel bar is approximately 1.58 kg/m.
350x450mm with 12-16mm rebars on 5m span
use 400x400mm with a rebars of 8-16mm dia. for 4-5m span.
The unit weight of rebars is typically around 7.85 kg/m³. In a reinforced concrete mix with a compressive strength of 60 MPa, the amount of reinforcement steel used is usually between 1-2% of the total volume of concrete. Therefore, the weight of rebars per cubic meter of reinforced concrete at 60 MPa would be approximately 78.5 kg/m³ to 157 kg/m³.
carats are a unit of weight. Millimeters are units of volume. So, the question is unanswerable. It's like asking "how many pounds in a foot?".
1.579kg/m
give me formula for weight in kg 8mm 10mm 12mm 16mm

Rolling Margin is the deviation of actual unit weight to that of Standard unit weight as per IS Standards. Rolling Margin is calculated as : Sectional weight = Weight of Steel Bars dia wise / length of the bars. As per IS Standards unit weight of the Bars is calculated as dia x dia / 162 Rolling Margin is deviation of actual sectional weight to that of IS Standard unit weight. Standard Rolling Margin for different dia reinforcement bars used for construction purposes: 8mm to 10mm +- 7% 12mm to 16mm +- 5% 20mm & Above +- 3%
16mm weighs 1.552 kg/m 1 metric tonne 1000 kg So about 644m length
There is no constant value for the ratio of the rebars and concrete volume. The rebars depends on the structural designer's safety factor and the factors affecting the framing like wind, earthquake and soil.
