Weight = Volume X Density
= width (mm) X Thickness (mm) X 7.85 Kg/mm3
= (40 X 20) X 0.00785 (converted the 7850 kg/m3 to 0.00785 g/mm3)
= 6.28 Kgs/ metre
For Circular Rebars (most used formula at site level)
this formula is for deformed steel bar .
Formula for Unit weight of steel = D2/162.28 Kg/m
Let’s take an example,
If we want to calculate the unit weight of 8mm steel rod of 2-metre height,
Weight of steel = 82/162.28
= 0.3944 kg/m * 2m
= 0.79 kg
if we want to calculate steel square b
