Here is the derivation of that D2/162.2, Weight of steel bar per meter = Area of the steel x Density of steel x Bar length. = (3.14 x D2 /4) x 7850 kg/m3 x 1m (refer these posts basic formulas & unit weight of materials) = (D2 x 6162.25)/(1000 x 1000)
In order to calculate the weight of steel plate, one must know the steel plate thickness and the steel plate density or steel plate specific weight, normally expressed in pounds per cubic foot (lbs/ft3). The calculation of steel plate weight is essential to estimating the steel plate prices. The carbon steel density is 489.6 pounds per cubic foot while steel thickness is expressed in inches. In order to correctly calculate the steel plate weight the unit must be the same.
