What is the Weight of a 12mm Rod? Full Calculation Explained

When planning any construction project, understanding the 12mm rod weight is essential for accurate material estimation, budgeting, and structural planning. Whether you are building a residential house, commercial building, or infrastructure project, knowing the weight of TMT bars helps avoid material shortages and unnecessary expenses.

What is the Weight of a 12mm Rod?

The standard weight of a 12mm TMT bar is approximately 0.888 kg per meter. This value is calculated according to the standard formula used in the steel industry:

Weight per meter = (Diameter × Diameter) ÷ 162

For a 12mm rod:

(12 × 12) ÷ 162 = 0.888 kg/m

This means that every meter of a 12mm TMT bar weighs around 0.888 kilograms.
