There is a formula to calculate the unit weight of steel bars. I’ll come that point later.

Why do we need to know the unit weight of steel bars?

When we estimate the steel bars for a Reinforced Concrete member we get the length of that as a result. For example, 1000 feet 20mm ø bar or 500 feet 16mm ø bar, etc (ø – symbol of diameter).

But steel bar suppliers measure the steel bars as weight. So we have to order them in weight for purchasing. The weight of steel bars can be expressed in kg or quintal or ton. 1 quintal = 100 kg1 ton = 1000 kg or 10 quintal

I work as a Civil Engineer. I want to learn everything new in the field of project management and to participate with those interested in learning this field.
