Steel, also known as rebar or reinforcing bars embedded in concrete elements to increase their tensile strength. As we know, steel is used to form structural members such as columns, beams, foundations, footings and building slabs. Various sizes of steel bars are supplied by the supplier in lengths of 12 meters or 40 feet.

The unit mass of steel or rebar is the ratio between the weight of the steel and its unit volume. It is usually expressed in kilograms per cubic meter (kg/m3) or pounds per cubic foot (lb/ft3). The unit of mass for steel is 7850 kg/m3 (kilograms per cubic meter) or 490 lbs/ft3 (pounds per cubic foot).

Unit weight of steel: The unit weight of steel is defined as the ratio between the weight of steel and the unit volume of steel, the unit weight of steel is usually measured in kg per cubic meter and is 7850 kg/m3, measured in kN per cubic meter is 78.5 kN/m3 or measured in grams per cubic centimeter is 7.85 g/cm3 which is roughly equivalent to pounds per cubic foot is 490 lbs/ft3 or measured in pounds per cubic yard is 13,231 lbs/ yd3.

Typically, the diameter of steel rods is 8 mm (2.5 soot), 10 mm (3 soot), 12 mm (4 soot), 16 mm (5 soot), 20 mm (6 soot), 25 mm ( 8 soot), 32 mm etc. or U-bend lengths of 12m or 40ft.

And read steel weight bar, steel weight formula, derivation d2/162, different sizes of steel bars, 8mm steel weight per meter, 10mm steel weight, 12mm steel weight, weight of 16 mm steel bar and 20 mm steel weight.

The unit weight of steel is defined as the ratio between the weight of the steel and its unit volume, the weight of steel is measured in kilograms (kg) and pounds (lbs) and its volume is measured in cubic meters (m3) and feet. cubic (ft3). Then its unit weight = unit mass/unit volume, represented as W = m/V, where W is the unit weight of the steel, m is the mass, and V is the volume. It is also known as specific gravity of steel or density of steel and its SI unit is kilogram per cubic meter (kg/m3). Steel is the most used element in civil engineering for construction. Once the unit weight of steel is known, it is easy to calculate the amount of steel needed for projects.
