This table in the below shows the theoretical weight of square bars of various grades, measured in millimeters, in both kilograms per meter and pounds per foot.

The weight of a square bar is an important consideration in a variety of industries, from construction to manufacturing.

The table includes measurements for grades ranging from 5.5mm to 200mm. For example, a 5.5mm square bar has a theoretical weight of 0.237 kg/m or 0.16 lb/ft, while a 200mm square bar has a theoretical weight of 3.14 kg/m or 2.11 lb/ft.

As the grade of the square bar increases, so too does its theoretical weight. This information is crucial for professionals who need to select the right materials for their projects, and ensuring safety and efficiency.

The following table lists the theoretical weight of 5.5-200mm square bar in kg/m.
