What are in this post?
In this post we have shared the method to calculate Weight of TMT Bars Per Bundle and Per Meter.
After reading this blog post, you will be able to calculate the total weight of a bundle of TMT bars of sizes 8mm, 10mm, 12mm, 16mm, 20mm and 25mm and also calculate the weight per meter of TMT bars of each size easily. For your convenience, the weight-charts of TMT bars per bundle per meter are also posted in this blog post.
Every bundle of different sizes TMT bars has different numbers of TMT bars. But each TMT bar comes with length 12 meter (40 feet). So different sizes TMT bars have different per meter weight according to their diameter.
TMT bars are available in the market at the rate of per piece and per kg. Therefore, it becomes necessary for those who buy bars to know how many bars are in a bundle and what is the weight of a bundle of bars of each size. You will get all this information after reading this post. Along with this, the method of calculating the weight per meter of bars of different sizes has been told in this post.
Calculation of Weight of TMT Bars Per Bundle and Per Meter
Here you will be read about no. of TMT bars in a bundle and calculation of weight per bundle and weight per meter of 8mm, 10mm, 12mm, 16mm, 20mm and 25mm sized TMT bars in three different sections.
No. of TMT Bars in a Bundle
With the below table you can easily understand the total no. of TMT bars in a bundle.

Calculation of Weight of TMT Bars Per Meter
Every TMT bars come with length 12 meter (40 feet). But each TMT bars has different weight per meter. If you have knowledge about the size (diameter) of TMT bar, you can easily calculate the weight per meter of TMT bar of any size. The size (diameter) of the TMT bar is written on the every TMT bar.
Formula to Calculate the Weight of TMT Bars Per Meter
The formula to calculate the weight per meter of TMT bars is D²/162 kg.
Here D is the diameter (size) of TMT bar which is given on every TMT bar.
For example, if you have a 8mm TMT bar. Then the weight per meter of the 8mm TMT bar is = 8²/162 kg = 0.395 kg.

10 mm TMT Bar |
0.617 kg |
12 mm TMT Bar |
0.888 kg |
16 mm TMT Bar |
1.580 kg |
20 mm TMT Bar |
2.469 kg |
25 mm TMT Bar |
3.858 kg |
Calculation of Weight of TMT Bars Per Piece
The calculation of weight per piece of any sized TMT bar is very easy. You only need to remember the formula. And at the same time it is also necessary to know that the size of each TMT bar is 12 meters.
Formula to Calculate the Weight of TMT Bars Per Piece
The formula to calculate the weight per piece of any sized TMT bar is (D²/162)×12 kg. (Here D is the diameter of TMT bar.)
For example, we have a piece of 8mm TMT bar. Then the weight of a piece of 8mm TMT bar is = (8²/162)×12 kg = 0.395×12 kg = 4.74 kg.

Calculation of Weight of TMT Bars Per Bundle
You can easily calculate the weight per bundle of any sized TMT bar. If you have knowledge about the number of TMT bars in a bundle and weight of TMT bars per piece.
With the help of the above table you can get the weight per piece of any sized TMT bar. The number of TMT bars in a bundle of TMT bars of sizes 8mm, 10mm, 12mm, 16mm, 20mm and 25mm are 10, 7, 5, 3, 2 and 1 respectively.
Formula to Calculate the Weight of TMT Bars Per Bundle
The weight per bundle of any sized TMT bar is calculated by given formula.
Weight of one bundle TMT bars
= no. of TMT bars in a bundle × Weight per piece
Example: For 8mm TMT bars,
Weight of one bundle 8mm TMT bars
= no. of TMT bars in a bundle × Weight per piece
= 10×4.74 kg
= 47.4 kg.
