How To Calculate Weight Of Steel

We knew that the D²/162.2 formula is using to calculate the weight of rounded bar in Kg/m. Then how to calculate the weight of Steel plate or irregular shape?

So in this post, we are going to discuss how to calculate steel bar weight and how to calculate steel plate weight.

How to calculate Weight of Steel

The rounded steel bar weight has been calculated by the D²/162.2 formula. At first, we are going to see the derivation of unit weight of steel formula for round bars.
