How to calculate weight of 8 mm Steel bar per metre,weight of 8 mm Steel bar**,**in this topic we know about how to calculate weight of 8 mm Steel bar per metre.

If you have any project related with building construction we have require reinforcement diameter of 8 mm Steel bar in various purpose like footing and roof casting of slab and formation of mesh in foundation footing and also formation of various site of stirrup used as tie purpose for reinforcement used in column, beam and slab.

In this topic we know about what is standard weight of 8 mm Steel bar and their Unit Weight of Steel. And also calculate Unit Weight of 8 mm Steel bar per metre.

**weight of Steel bar**

we know that there is two types of Steel **TMT and TMX used in construction of building**. Weight of TMT bar depend upon its properties brand and according to size so might be little data vary from actual weight of Steel.

**Weight of 8 mm steel bar**

8 mm TMT bar have approx 12 metre in length and diameter is equal to 8 mm and their number is about 10 in one bundle.

**How to calculate unit weight of 8 mm Steel bar per metre**

**Given**:-

Dia of tmt bar = 8mm

Length of tmt bar = 12 meter

Number in one bundle = 10 nos

**weight of 1meter tmt bar of dia** 8mm

Weight = volume × density

Density of tmt bar = 7850 kg/m3

We have one formula for calculation of weight of Steel

Weight = (D^2/162) L kg/m

Where D = dia of steel bar=8mm

L = length of steel =1m

Putting all the value in given formula we get

Weight = (8×8/162)× 1 kg/m

Weight = 0.395 kg/m

0.395 kg is unit weight of 8 mm Steel bar per metre

** weight of 1 TMT bar of dia 8 mm**

We have length of 1 bar L= 12 meter

Dia of tmt bar = 8mm

Weight = (8×8/162)×12m

Weight = 4.74 kg

4.74 kg is weight of one piece of TMT bar of 8 mm

**weight of one bundle of TMT bar of dia 8 mm**

We have no. of bar in 1 bundle =10

Length of 1 bar = 12 meter

Weight = (8×8/162)×12×10 kg

Weight = 47.407 kg

47.407 kg is weight of one bundle of TMT bar dia of 8 mm.
