How much does 1 meter of 14 reinforcement weigh?
When using rebar to strengthen foundations or other structures, an important question arises: how much does the rebar weigh? This is necessary in order to calculate the required volume of materials, since reinforcing bars are usually sold by weight.
How to calculate the weight of reinforcement?
“Weight classes” are best described in relation to their diameter. For clarity, we present them in the table.
Knowing the weight of 1 meter of reinforcement, you can determine the required quantity. For example, when strengthening the foundation, the required amount of reinforcement per meter is calculated, comparing it with the corresponding diameter, you can calculate the required quantity to order.
In addition, having knowledge of the weight of a meter of reinforcement makes it possible to estimate:
- reinforcement coefficient (weight of reinforcement divided by volume of poured concrete);
- required material for 1 cubic meter of foundation concrete.
How much does the reinforcement weigh in linear meters?
Here the weight according to GOST depends directly on the diameter, since each 1 m rod of different diameter will have a different weight. For example, you use d 20 material, which requires 200 meters in length. The weight of fittings in this category is 2.47 kg per meter, so you need to order 200x2.47 = 494 (kg). In addition, the weight, based on linear meters, depends on the nature of the profile surface: will it be corrugated or smooth.
The weight of a meter of mesh reinforcement for the frame of a reinforced concrete foundation, screed or plastering work, brickwork will depend on the size of the fabric, the cell, as well as on the diameter of the wire itself.
How much does a meter of reinforcement weigh based on length? For purchase, the calculation is carried out taking into account the total length of the rods that are in the pack and the weight of a linear meter (according to the table). In order to convert from meters to tons, the specific gravity is multiplied by the number of linear meters.

Answers from forum users and experts to the question: How much does a meter of reinforcement weigh?
I can help you with this question because it was also the case that I was transporting fittings in the trunk. A meter of reinforcement weighs about 2 kilograms. but the point is not the weight, but how you fold it into the trunk, because you can take 5 meters if you fold it poorly, but you can take 10 meters. So when you fold, stack one on top of the other

Often, when buying metal products, beginners cannot understand the simplest things like size, weight and other metric characteristics. For example, when purchasing reinforcement, you should know how to determine its weight.
How much does reinforcement of different diameters weigh?
The indicator of how much the reinforcement weighs depends on:
- the type of metal from which it is made;
- the length of the rods and their diameter;
- manufacturer, since these products can be manufactured in accordance with GOST or according to the company’s (factory’s) own technical specifications.
The diameter of the reinforcement according to GOST (steel grade A500C) can range from 6 mm (the thinnest) to 40 mm thick (the thickest). Most often, in technical and commercial documents when selling this material, the weight of this product is presented per 1 linear meter.
How much does a meter of reinforcement weigh depending on the diameter?
- 6 mm – 0.222 kg;
- 8 mm – 0.395 kg;
- 10 mm – 0.617 kg;
- 12 mm – 0.888 kg;
- 14 mm – 1.21 kg;
- 16 mm – 1.58 kg;
- 18 mm – 2 kg;
- 20 mm – 2.47 kg;
- 22 mm – 2.98 kg;
- 25 mm – 3.85 kg;
- 28 mm – 4.83 kg;
- 32 mm – 6.31 kg;
- 36 mm – 7.99 kg;
- 40 mm – 9.87 kg;
- 45 mm – 12.48 kg;
- 50 mm – 15.41 kg;
- 60 mm – 22.19 kg;
- 70 mm – 30.21 kg;
- 80 mm – 39.46 kg.
The weight of a linear meter of reinforcement can be calculated independently using a simple formula
1 m x (3.14 x D x D/4),
where D is the diameter of the reinforcement. The resulting figure must be multiplied by the specific gravity of the reinforcing steel, which is equal to 7850 kg/m3. For example, if you need to calculate the weight of one meter of reinforcement with a diameter of 14 mm:
Volume: 1 meter x (3.14 x 0.014 m x 0.014 m / 4) = 0.00015386
Weight: 0.00015386 x 7850 kg/m3 = 1.207. If rounded to the nearest hundredth, the weight is approximately equal to the weight from the table above.
It will also be useful to familiarize yourself with other information that will help you figure out how to purchase and transport reinforcement - we advise you to study our article How to knit reinforcement correctly.
What is the weight of the reinforcement?
When building a house or other construction work, construction (metal) reinforcement is used for the base of the foundation, on the floors, between windows, or on the blind area around the house.
Metal fittings made in Ukraine
In this article we will talk about Ukrainian-made metal reinforcement, and not fiberglass or basalt reinforcement - we do not sell this type of reinforcement.
The amount of reinforcement that is given to you by a foreman or when you independently calculate a house is usually calculated in meters. This is easy to calculate, since suppose you have a house 10 m by 15 m, depending on the type of foundation and its height, you can calculate how many meters of reinforcement you need. Experienced builders can already tell you a clear weight because they know the weight of the reinforcement, but it happens that they exaggerate the amount of metal required for the purpose of profit, what is there to hide.
How to calculate the theoretical weight of reinforcement?
And now specifically on the weight of reinforcement of each diameter. There is a formula with which you can easily calculate the theoretical weight of the reinforcement, but here it should be emphasized that it is theoretical, but not practical: m = d2/162.272, where m is the mass of one meter, d2 is the diameter of the reinforcement squared, and the number 162.272 is a constant number in the fittings. But, unfortunately, this weight agrees with the reference book, but this is also a theory.
Here's what happens in practice:
- reinforcement with a diameter of 8 mm - according to theory, a meter should weigh according to the formula 8x8/162.272 = 395 grams, but in fact the weight of one meter is 430 grams, some trading companies consider the weight of a meter to be 450 grams. It should be noted here that such a weight rarely happens, but very rarely in other cases - this is simply additional income for metal depots or trading organizations;
- reinforcement with a diameter of 10 mm - here, according to theory, 617 grams, in nature 630 - 640 grams, but not like 660 or 700 grams - this is no longer fair trade;
- fittings with a diameter of 12 mm - the weight of a linear meter according to the reference book is 888 grams, when weighed 900 grams - no more, yes it happens, but rarely 890 grams;
- reinforcement with a diameter of 14 mm - the weight of a linear meter in theory agrees with practice 1 kg 200 grams - there are no miracles here, just reality. I don’t know how to explain this. Maybe this is due to the high demand for reinforcement with diameters of 8, 10, 12 mm.
Manufacturers ship in tonnage and it is profitable for them to sell a larger quantity by weight; accordingly, they somehow increase some element in the composition of the metal.
Although somehow the reinforcement arrived, which was produced in Moldova, then the weight of the 8 mm reinforcement coincided with the theory - exactly 417 grams.
— reinforcement 16 mm — weight in theory 1 kg 570 grams, weight in practice 1 kg 600 grams;
— reinforcement 18 mm — weight per linear meter 2 kg — theory and practice converge;
— reinforcement 20 mm — weight of one meter 2 kg 47 grams — theory and practice converge.
Well, we’ll finish with this diameter, since thicker reinforcement diameters are not used in construction of up to 5 floors.
This is the answer to the question: what is the weight of the reinforcement?
Recommendations for purchasing fittings
You should be warned that if the weight of the fittings is overestimated in comparison with the weight that was provided to you here, beware of such sellers. Because they are simply fooling you.
Prices for rolled metal have skyrocketed, and everyone is trying to buy cheaper and may end up with dishonest sellers who, under the guise of a low price, will bring you not 1 ton, but 900 kg, but you will pay 300 UAH less per ton than the average market price, but you will also receive 100 kg less. Therefore, ask strictly when purchasing.
And in one ton of reinforcement 12 mm - 1111 meters? - if yes, the seller agrees, then everything is fine, but if he starts -. use. it means something is wrong - they want to deceive you.
The weight of reinforcement 8 mm in diameter is given according to an extract from the assortment specified in GOST
If I understand correctly, then you are not interested in the weight of 8 mm reinforcement in general, but most likely the weight of one meter of reinforcement. This question could be asked in the Yandex PS a little differently: the weight of a meter of reinforcement is 8 mm, the weight of a linear meter of reinforcement is 8 mm, the conditional weight of reinforcement is 8 mm, the specific or theoretical weight of reinforcement is 8 mm, the calculated weight of reinforcement is 8 mm, and so on.
Despite the fact that these questions are formulated slightly differently, in general we are talking about the same thing. In fact, you want to calculate how much the 8 mm diameter reinforcement that you have in stock weighs, or the 8 mm reinforcement that you want to buy, but for some reason, it is not convenient for you to weigh the 8 mm reinforcement on a scale and it is more convenient to refer to the table reinforcement weights. Such a table of reinforcement weights is in GOST for reinforcement.
From the reinforcement weight table, you need to find out the theoretical weight of one linear meter of reinforcement with an 8 mm diameter.
Weight of reinforcement 8 mm diameter #8212; according to GOST
We did some not very complicated work for you, so that you do not need to download a free table of reinforcement weights or download the entire range of reinforcement, and we found the exact value of the mass of one linear meter of 8 mm reinforcement.
REINFORCEMENT WEIGHT 8 mm #8212; is 0.395 kg per linear meter.
How to use the value you found now: the weight of reinforcement 6 mm in diameter?
In fact, using the table for calculating the weight of reinforcement is very simple and convenient, although it looks somewhat #171;intimidating#187; at first glance. There are quite detailed tables of the weight of linear meta reinforcement . taking into account different types of fittings according to GOST (there are actually three of them). I'll show you with an example. So, for example, you want to buy 25 meters of reinforcement with a diameter of 8 mm.
Perhaps you need to reinforce the foundation for a fence or solve some other construction problem. When selling 8mm reinforcement, the seller usually sets the price of the reinforcement in tons; it is in tonnage that he buys it at the factory. He sells you 8 mm reinforcement in meters, in linear meters, of which you need exactly 25 m. That is, the price of 8 mm reinforcement per ton tells you absolutely nothing.
In order to somehow convert the number of linear meters of 8 mm reinforcement you have into #171; categories close to: price per ton of 8mm #187; reinforcement, you need to calculate how much your 25 meters of reinforcement with a diameter of 8 mm weigh. We find line #8212 in the table for calculating the weight of reinforcement; the weight of a linear meter of 8 mm reinforcement (we have already done this for you #8212; see above), opposite shows the weight of a meter of 8 mm reinforcement in kilograms #8212; 0.395 kg.
Now, knowing the weight of one meter of 8 mm reinforcement, we must multiply it by the number of meters #8212; 0.395 x 25 = 9.875 kg. That is, your 25 linear meters weigh exactly 9.875 kg. This is the THEORETICAL WEIGHT OF A METER OF REINFORCEMENT 8 mm in diameter.
