MS square bar is a long, rectangular metal bar that is utilized extensively in the industrial and commercial sectors. It is very important in engineering work and has numerous uses, including crane gantries, bullock cart axles, conveyors, trucks, trailers, and tippers. It is also used as a bright bar and anchor bolt, among other things. There are numerous metal varieties of the square bar to choose from, including hot- and cold-rolled steel, aluminium, stainless steel, mild steel, and more.

The weight of the square bar calculator and its formula for MS bars in sizes 10mm, 12mm, 14mm, 16mm, 17mm, 20mm, 25mm, 32mm, 40mm, 42mm, 50mm, 53mm, 56mm, and 63mm are discussed in this article. Their weight is calculated using multiple formulas in kilograms per meter (kg/m), kilograms per foot (kg/ft), and pounds per foot (lb/ft).

MS square bar weight calculation formula, we should take derivation,

Area of square bar = S^2, where S is the side of the square bar, taking H as the height of the bar, then its volume is equal to S^2 × H.

The volume of square bar = S^2 × H,

Taking its density = 7850kg/m3, and Height = 1m,

Weight = Volume × density,

Weight of square bar = S^2×H × 7850kg/m3,

Weight = S^2 ×1/(1000)2 m2 ×7850kg/m3,

Weight = S^2× 0.00785 kg/m = side.mm2 × 0.007850 kg/m, when its measured in pound per foot, then their weight formula is side.mm2 × 0.005274 lb/ft, and when its measured in kilogram per foot, then their weight formula is side.mm2 × 0.002392 kg/ft.

It is recognized as a Carbon Steel square bar with a low quantity of carbon that's why it is known as a "low Carbon Steel square bar ." Mild steel/MS square bar is a highly malleable and highly adaptable metal suitable for commercial and industrial applications. The weight-based carbon content ranges from 0.05% to 0.25%.

The unit weight of a square bar is defined as the weight per unit volume, expressed in kilograms per meter3, meaning that the unit weight of a square bar is approximately 7850 kilograms per cubic meter. Their unit weight, expressed in pounds per square foot (lb/ft3), is 490 lb/m3.
