Calculate Weight of Steel rebar from length – 8,10,12,16, 20mm..

 

Calculate Weight of Steel rebar from length – 8,10,12,16, 20mm..


Steel rebars are available in different diameters like 8mm, 10mm, 12mm, 16mm, 20mm, 25mm, etc.., In this article, I am going to show you a simple method to calculate the weight of steel rebar from its length (meter and foot) with some examples. In the end, I will also give you a list that contains the weight of all steel rebar per meter and foot.

The calculations given below are valid for all steel rods like TMT, CMT, mild steel, etc..,

Case 1

If the length of the rebar is in meter and the diameter of rebar is in mm, the weight of steel rebar W = (D2/162) * L

i.e., Weight of steel reinforcement= (Diameter square/162) * Length

Case 2

If the length of the rebar is in feet and the diameter is in mm, the weight of steel reinforcement W = (D2/533) * L

Examples

Let’s find the weight of TMT steel rod of length 1 meter @ 8mm dia

Weight of 1 meter @ 8mm steel rod = (82/162) * 1 = 0.395 kg

Weight of 12 meter @ 8mm steel bar = (82/162) * 12 = 4.74 kg

Weight of 40 feet @ 8mm steel bar = (82/533) * 12 = 4.80 kg

Weight of 1 meter @ 10mm steel rod = (102/162) * 1 = 0.617 kg

Weight of 12 meter @ 10mm steel bar = (82/162) * 12 = 7.407 kg

WEIGHT OF STEEL REBAR FROM LENGTH

Mostly, Steel rebars like TMT are supplied in the length of 12 meters or in 40 feet.
