What is this blog post about?

At the time of buying steel bars, calculation of unit weight of steel bars is a most important thing. Because in most cases civil engineers or contractors recommend to buy steel bars in pieces, bundles or in tons. In most cases, the estimation of steel bars are calculated in tons and also sometimes dealer sell steel bars at per kg or per ton rate.
This blog post helps you to get the exact result of the searches unit weight of steel bar or steel bar weight per meter. You can find here the unit weight of all sizes steel bars particularly.

Few Important Points about TMT Steel Bar

• TMT steel bars are supplied in U bent or straight rods.
• Standard length of TMT steel bar (any size) is 12 meter or 40 feet.
• As per IS 1786:2008 the tolerance of TMT steel bars should adhere as per IS guideline.
• TMT steel bars are manufactured in different diameters: 8 mm, 10 mm, 12 mm, 16 mm, 20 mm, 25 mm, 28 mm, 32 mm.
• Weight of TMT steel bars can be explained in Kilogram or Quintal or Ton, where
1 Quintal = 100 kg ‖ 1 Ton = 1000 kg

Just scroll down and learn how to calculate the unit weight of steel bars of any size (diameter).

The unit weight of 8mm, 10mm, 12mm, 16mm, 20mm, 25mm steel bars are given below and also the formula to derive the unit weight of steel bars given.

Unit Weight of Steel Bars

The unit weight of steel bar is the weight of a steel bar of one meter length in kg. For example, the standard weight of 8mm steel bar of 1 meter length is 0.395 kg. So the unit weight of 8mm steel bar is 0.395 kg.

Unit Weight of Steel Bars: Formula

There is a formula to calculate the unit weight of any size TMT steel bars. It is D²/162, where D is the size (diameter) of the TMT steel bar and the result is given in kg.

Unit Weight of Steel Bars: Calculation

Unit weight of steel bars is calculated by the formula D²/162, where D is the size (diameter) of the TMT steel bar. For example, unit weight of 8mm steel bar is 8²/162 kg = 0.395 kg.

Unit Weight of 6mm Steel Bar Weight Per Meter
