Rod is known as steel bar and Reinforcement bar. Rod is also known as rebar and it is a short form of the reinforcement bar. Steel bar comes in different sizes and it sells according to weight. Many countries of the world follow their own different measurement, and gradation systems for rods. The United States and some European countries follow the imperial measurement system and the rest of the world follows the metric system. So In this article, we will discuss 8mm rod weight per foot, 8mm rod weight per meter, 8mm rod weight per piece, and 8mm rod weight per bundle.

Rod is used in reinforced concrete structures and load-bearing structures, Like beams, columns, foundations, Dams, bridges, etc. Rod gives more strength to the structure in which it is used. You can not imagine concrete structure construction without using rods.

The steel rod surface is deformed with ribs. The ribs of the rod prevent the slipping risk and it helps to get a better bond after tieing with steel wire. The steel rod is coated with epoxy resin which prevents the rod from rusting in a moist environment.

## 8mm rod weight per foot, per meter, per piece, and per bundle

Rod comes in different sizes like 8mm, 10mm, 12mm, 16mm, 20mm, 25mm, 32mm, etc. But the **length of the steel bar** is 12 meters or 40 feet. 8mm rod is generally used for the slab, roof slab, and such like structures. It is a very thin bar so it can not use in other structures like beams, columns, etc. As I already tell you different countries have their own gradation and measurement system. So We will discuss 8mm rod weight per foot, per meter, per piece, and per bundle.

Generally, there are two formulas for calculating the rod weight.

- D
^{2}L/162. This formula is usable when rod length is given in meters. - D
^{2}L/533. This formula is usable when rod length is given in foot.

In the above two formula D represent the diameter of the rod and L represent the length of the rod.

### 8mm rod weight per foot

Diameter of the rod = 8

Length of the rod = 1 foot.

Therefore rod weight = D^{2}L/533

= (8)^{2} × 1/533

= 64/533 = 0.120 kg.

So, 8mm rod weight per foot is 0.120 kg.

### 8mm rod weight per meter

Diameter of the rod = 8

Length of the rod = 1 meter.

Therefore rod weight = D^{2}L/162

= (8)^{2} × 1/162

= 64/162 = 0.395 kg.

So, 8mm rod weight per meter is 0.395 kg.

### 8mm rod weight per piece

As I already tell you steel bar comes in 12 meters or 40 feet. So if you will take rod length in meters then you have to use (D^{2}L/162) this formula. But if you will take rod length in feet then you have to use (D^{2}L/533) this formula.

Here I will take rod length in meters. So 1 piece rod length is 12 meters.

Diameter of the rod = 8

Length of the rod = 12 meters.

Therefore rod weight = D^{2}L/162

= (8)^{2} × 12/162

= 768/162 = 4.740 kg.

So, 8mm rod weight per piece is 4.740 kg.

### 8mm rod weight per bundle

To calculate the rod weight per bundle we have to know how many 8mm rod comes in a bundle. 10 rods come in a bundle. There are so many methods to calculate rod weight in 1 bundle. But we will use the easiest way.

We know the 1 piece 8 mm rod weight and there are 10 pieces in an 8 mm rod bundle.

1 piece 8mm rod weight = 4.740 kg.

So, 1 bundle 8 mm rod weight = 1 piece bar weight × total number of rods in a bundle.

= 4.740 × 10

= 47.4 kg.

Therefore, 8mm rod weight per bundle is 47.4 kg.

#### Conclusion

In this article, we have discussed there is the weight of 8mm rod is 0.120 kg per foot, the weight of 8mm rod is 0.395 kg per meter, the weight of 8mm rod is 4.740 kg per piece, and the weight of 8mm rod is 47.4 kg per bundle.

#### FAQ

**How many 8mm of rods come in 1-ton weight?**

There are 211 piece rods of 8mm come in 1 ton. Because 1 ton is equal to 1000 kg and 1 piece 8 mm rod weight is 4.740 kg. So 1000 ÷ 4.740 = 210.970 = 211 piece.

**How many 8mm of rods come in 100 kg or 1 quintal?**

There are 21 piece rods of 8mm come in 1 quintal. Because 1 quintal is equal to 100 kg and 1 piece 8mm rod weight is 4.740 kg. So 100 ÷ 4.740 = 21.097 = 21 piece.
