12mm rod weight: Everything You Should Know

TMT bars stand as the most important structural element in any form of house construction. Whether it's your cozy home or a towering commercial edifice in the making, TMT bars play an irreplaceable role. As you progress on the research for the best TMT bars, your choice revolves around diameter specifications. While length typically adheres to a universal standard, diameters offer a varied set of options. The TMT bars come in diameters of 8 mm, 10 mm, 12 mm, 16 mm, 20 mm, and 32 mm, allowing you to select in alignment with your construction demands. Determining the right quantity of TMT bars hinges on your project's unique prerequisites. Calculating the weight of the bars is a pivotal consideration, and for your ease, we furnish you with a TMT bar weight chart.

What is weight of 12 mm steel rod?

Here's what our guide entails:

1. Weight Chart
2. Individual TMT Bar Specifications
3. Formula for Calculating TMT Bar Weight

Let's delve into a specific example: a 12 mm TMT bar adheres to these quality and utility criteria: Now, let's explore the formula to gauge the weight of TMT bars. When you procure TMT bars, they often come bundled with similar weights to maintain consistency, following the IS:1786-2008 standard.

TMT Steel Bar Weight Chart

SIZE	WEIGHT (Kgs/metre) as per ISI
MM	MIN	NOMINAL	MAX
8 mm	0.367	0.395	0.423
10 mm	0.574	0.617	0.66
12 mm	0.844	0.888	0.932
16 mm	1.501	1.58	1.659

For 8 mm, 10 mm, 16 mm and other sizes, compare the complete TMT steel bar weight chart.

Rod unit weight is expressed in kilograms per metre (kg/m). The estimating formula is D² ÷ 162 kg/m, where D is the nominal diameter in millimetres. The table above lists 0.888 kg/m as the published nominal unit weight for a 12 mm bar.

Using that published nominal value, a 12 m bar weighs 0.888 × 12 = 10.656 kg, or approximately 10.66 kg. The formula gives approximately 0.889 kg/m when rounded to three decimal places; the worked example uses the table’s nominal value.
