The weight of a 12mm TMT (Thermo- Mechanically Treated) bar can vary slightly based on the specific density of the material used by the manufacturer. As a rough estimate, the weight of a 12mm TMT bar is around 0.89 kilograms per meter, 0.27 kilograms per foot, 10.667 kilograms per piece, or 52 to 53 kilograms per bundle.

12mm tmt bar weight per meter & per foot, hi guys in this article we know about calculation of weight of Steel bar 12mm size and 12mm steel bar weight per foot & per metre. calculation formula for steel weight per metre and per feet.

As we know that steel is load bearing material are used in construction line in field of industrial construction work, building construction, formation of bridge and dams superstructure of Industrial and commercial building, residential building and many types of construction in **civil engineering**.

One 12mm steel bar is approximately 12 metre or 40 feet, this help in calculation of steel weight. Number of TMT bar present in one bundle of 12mm size is 5

Calculation of 12mm Steel weight we used formula for Unit Weight of Steel. Unit Weight of steel rod is define as weight of Steel bars per metre in kg or per foot in kg. So we used two formula calculation of steel weight.

12mm Steel rod weight calculation formula per metre in kg or per foot in kg help you to find weight of one bundle of 12mm Steel bar and weight of one piece of Steel.

**The formula we are using for 12mm steel bar weight calculation are following:-**

**● 1) D^2 L/162 :- this formula are used for weight of tmt bar per metre in kg (m/kg)**

**● 2) D^2 L/533 :- this formula are used for weight of tmt bar per feet in kg (ft/kg).**

Where D = diameter of tmt bar and L is length of tmt bar and numerical figure 162 used for weight per metre in kg and 533 used for weight per foot in kg.

**1) D^2 L/162 and D^2 L/533 derivation**

**12mm tmt bar weight per meter & per foot**

12mm steel bar weight per metre calculation we used the formula D^2 L/162 and per foot D^2 L/162. We know that 12mm dia of Steel bar have 5 number of Steel in one bundle and length of one piece of rod is 12 m.

Calculating 12mm tmt bar weight per metre we used the formula D^2 L/162, if dia of steel = 12mm, length of steel rods = 1 meter, then 12mm tmt bar weight per meter = (12×12×1)/162 = 0.889 kgs, so 12mm tmt bar weight per metre is 0.889 kgs.

Length of 1 steel rod = 12 meter, then weight of 1 piece of 12mm tmt bar weight in kg = (12×12×12)/162 = 10.667 kgs, so weight of 1 piece 12mm Steel rod is 10.667 kgs.

Length of 1 steel rod = 12 meter, number of steel in 1 bundle =5,then weight of 1 bundle of 12mm steel rod in kg = (12×12×12×5)/162 = 53.34 kgs, so weight of 1 bundle 12mm Steel rod is 53.34 kgs.

Calculating 12mm tmt bar weight per foot we used the formula D^2 L/533, if dia of steel = 12mm, length of rods = 1 feet, then weight of 12mm tmt bar per foot = (12×12×1)/533 = 0.27 kgs/ft, so 12mm tmt bar weight per foot is 0.27 kgs.

**● summary :-**

1) 12mm steel rod weight per meter is 0.889 kgs

2) 12mm steel rod weight per feet is 0.27 kgs

3) 1 piece 12mm steel rod weight is 10.667 kgs

4) 1 bundle (5 nos) 12mm steel rod weight is 53.34 kgs.
