Converting the weight of reinforcement into its length and vice versa is required when solving practical problems of calculating construction estimates, purchasing material in trade, and drawing up a reinforcement scheme for a concrete structure. As a rule, it is not difficult to find fairly accurate tables for converting one unit of measurement to another - they are available both in reference books and on the Internet.

How much reinforcement is in 1 ton: meters, pieces
The number of meters and pieces of reinforcement in 1 ton depends on the diameter of the rod used. It is necessary to know this when purchasing material, so that you can independently check the quantity of goods supplied, as well as calculate the volume of reinforcement for reinforcing monolithic structures.
Footage of reinforcement in ton: calculation example, table
Let's look at an example of how the calculation is made and find out how many meters of reinforcement with a diameter of 12 mm are in 1 ton.
To calculate, we need to know the mass of 1 meter, look at the table of the weight of the reinforcement, it is equal to 0.888 kg. Now we divide 1000 kg by 0.888 kg, we get 1126.13 m. For convenience, below is a table that immediately indicates the footage of the most popular steel rods in construction.
| Rod diameter, mm. | Number of meters in 1 ton |
| 6 | 4504,5 |
| 8 | 2531,65 |
| 10 | 1620,75 |
| 12 | 1126,13 |
| 14 | 826,45 |
| 16 | 632,91 |
| 18 | 500 |
| 20 | 404,86 |
| 22 | 335,57 |
| 25 | 259,74 |
| 28 | 207,04 |
| 32 | 158,48 |
| 36 | 125,16 |
| 40 | 101,32 |
| 45 | 80,13 |
Knowing how many meters are in 1 ton, you can easily convert the reinforcement from meters to tons. For example: we will convert 8956 m of rods with a diameter of 12 mm into tons. For this, 8956/1126.13=7.953 (t). In this way, any size of whip can be converted by simply dividing the total length by the length of 1000 kg.
Number of reinforcement pieces per ton: calculation example, table
Knowing the footage of the rods in 1000 kg, you can make calculations by the piece. Let’s also look at how to do this using an example, let’s calculate how many pieces of 12 mm reinforcement are in 1 ton, 12 m long and 11.7 m long (the most common lengths produced by factories).
To calculate the number of pieces, we take the total footage in one ton, for rods 12 mm long, it is equal to 1126.13 m, and divide by the length of the rod 12 m, we get 93.84 pieces, for a rod 11.7 m long, the result is 96.25 pieces . The table below shows the number of whips of the most common sizes (calculated values are rounded to the nearest tenth).
| Diameter of fittings, mm. | Number of pieces per ton of rods 11.7 m long. | Quantity for rod length 12 m. |
| 6 | 385 | 375,4 |
| 8 | 216,4 | 211 |
| 10 | 138,5 | 135 |
| 12 | 96,2 | 93,8 |
| 14 | 70,6 | 68,9 |
| 16 | 54,1 | 52,7 |
| 18 | 42,7 | 41,7 |
| 20 | 34,6 | 33,7 |
| 22 | 28,7 | 28 |
| 25 | 22,2 | 21,6 |
| 28 | 17,7 | 17,2 |
| 32 | 13,5 | 13,2 |
| 36 | 10,7 | 10,4 |
| 40 | 8,6 | 8,4 |
| 45 | 6,8 | 6,7 |
An example of a calculation using a table: let’s say for reinforcing aerated concrete blocks and an armored belt, you need 600 kg of 10 mm reinforcement. In order to make it convenient to transport, 12 meter rods were cut into 6 m lengths. To find out their number, take the table value of 135 (pieces per ton) and multiply by 0.6, equal to 81 pieces. Since they were divided in half, we multiply 81 by 2, we get 162 rods of 6 meters each.
Do not forget that when cutting reinforcement into short rods, its consumption for reinforcing the structure increases, since more overlaps will have to be made. It is worth taking this into account when calculating and purchasing materials for construction.
According to these tables, you can calculate the required tonnage of rods for reinforcing a strip foundation, monolithic belt and other reinforcing structures, based on the footage of the building. And also, you can calculate for yourself whether the material was brought to you correctly by recalculating its quantity.
How to calculate the weight of reinforcement per 1 linear meter using the table?
The weight of the reinforcement is a very important parameter both for the construction of reinforced concrete structures and for the construction of various buildings (for example, greenhouses). The weight of the iron parts must be taken into account when planning the construction of the structure itself. The calculation of the number of reinforcing bars in free and stressed zones, the distance between the bars, etc. depends on it.
In addition, the cost of construction will depend on the weight of a meter of iron stubble. It is cheaper to purchase iron rods at wholesale stores, where the cost is indicated per ton. Calculations in construction are made in linear meters. Therefore, it is important to be able to calculate how many meters of rod are in one ton.
