Steel formula:
Square tube weight per meter = (side length + side length) * 2 * thickness * 0.00785
Flat steel weight = width * thickness * 0.00785
Rebar and round bar weight per meter = diameter * diameter * 0.00617
Round tube weight per meter = (outer diameter - wall thickness) * wall thickness * 0.02466
Hexagon weight per meter = diameter of the opposite side * diameter of the opposite side * 0.0068
Weight per square meter of steel plate = thickness * 7.85
