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
16mm dia weight for running feet
50 mm dia gi pipe 4mm thick
9.8kg per m
unit weight of 60mm dia hallow ms pipe
50nb ms pipe unit weight
unit weight = 10.68 (outer dia. of pipe - thickness of pipe) x thickness of pipe unit will be 'lbs/foot' 1 lbs = 0.45359237 kg and 1 foot = 0.3048 meter or 1 meter = 3.2808 feet
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%
43 mm dia. is the good answer. KWB unit
32mm MS Rod 1Meeter Lenth
8mm dia : 0.395 kg/m 10mm dia : 0.617 kg/m 12mm dia : 0.888 kg/m 16mm dia : 1.579 kg/m 20mm dia : 2.467 kg/m 25mm dia : 3.855 kg/m These are standard unit weights based on the density of steel @ 7850 kg/m3
The unit weight of steel is 7850kg per cubic meter, so the unit weight of different bars can be calculated by multiplying the volume of 1m length of bar with the unit weight of steel.It can also be calculated simply by dividing the square of the diameter of bar in mm by 162.Diameter of bar unit weight calculation.8 0.395kg/m w=8x8/16210 0.617kg/m w=10x10/16212 0.889kg/m w=12x12/16216 1.580kg/m w=16x16/16220 2.469kg/m w=20x20/16225 3.858kg/m w=25x25/162
