Specific gravity of iron, properties, application, and table of values
Iron is an element of the eighth group of the secondary subgroup of the corresponding table of elements and is one of the most common metals in the earth's crust, ranking second after aluminum.
Iron in its simplest form is a malleable type of metal, white in color with a silvery tint. This type of material has a high ability to undergo chemical reactions, especially the process of corrosion in air at high humidity and temperature.
In pure oxygen, iron burns in its simple form. When finely dispersed in air, it ignites spontaneously.
Usually, the name iron refers to its various alloys with an impurity content of up to 0.8 percent. The latter make it possible to improve the ductility and softness of pure metal.
Alloys with carbon are used, where the composition includes cast iron about 2.14 percent of carbon and steel about 2.14 percent of carbon, as well as alloys with the addition of alloying metals.
In its pure form, iron is very rarely found in nature, most often in the composition of nickel iron-type meteorites. It ranks fourth in prevalence in the world.
Iron Specific Gravity Table
Since iron is a complex material, it is not possible to independently calculate the weight of iron, namely the specific gravity indicator, in the field. These calculations are carried out in special chemical laboratories. However, the average specific gravity of iron is known and is 7.874 g/cm3.
To simplify the calculations, below is a table with the values of the specific gravity of iron, as well as its weight depending on the units of calculation.

Properties of iron
Iron is a typical metal that is white in color with silvery and grayish tints. It has good ductility, pronounced magnetic properties, and also perfectly changes its properties under the influence of impurities. Iron is characterized by magnetism.
This type of elements is divided into four modifications according to their crystalline characteristics:
Approximately 95 percent of all metallurgical production comes from iron, making it one of the most sought after metals in the world. Among the main directions it is worth noting:

How much does a cube of wood weigh?
When starting to build a house or make renovations, sometimes you have to face questions that seem simple at first glance, but you can’t immediately answer them. It seems awkward to approach specialists with such a question, but you need to know for sure. For those who can turn to the Internet, it’s easier - type in a search engine “How much does a cube of wood weigh” and in half a minute received a comprehensive result. By the way, really, how much?
The effect of humidity on the weight of wood
The weight of wood does not always have the same value. What does it depend on? First of all, from the moisture content of the wood. If we compare, for example, oak and birch, it turns out that a cubic meter of oak weighs 700 kg, and a birch weighs 600 kg. But it could be different. Weighing a cubic meter of birch, we get 900 kg, and oak will show the same 700. Or in both cases it will be 700 kg. Why do we get such different numbers? In this case, the moisture content of the wood plays a role.
There are four degrees of humidity: dry (10-18%), air-dry (19-23%), damp (24-45%) and wet (above 45%). Thus, it turns out that different rocks with the same humidity have different weights, as in the first example above. If the humidity is not the same, then the weight may fluctuate in one direction or another. The standard humidity is 12%.
Different density - different weight
Another factor that affects the weight of wood is its density. The highest density of iron and ebony wood is from 1100 to 1330 kg/m3. Boxwood and bog oak are close to them - 950-1100. For ordinary oak, beech, acacia, pear, and hornbeam, the density is about 700 kg/m3. It is even lower for pine, alder, and bamboo - 500 kg/m3. And the lowest is for cork wood, only 140 kg/m3.
Why do you need to know the weight of a cubic meter of wood?
Having knowledge in this area is sometimes very important. When purchasing building material, its quantity cannot be determined by eye by a non-specialist. Knowing the dimensions of the timber or lining, the material from which they are made and its moisture content, simple calculations allow you to determine the weight of the purchased product. How much does a cube of wood weigh? In this case, the answer to this question will help you figure out whether the seller sent you the goods correctly.
Heat transfer from wood
In addition, there is another indicator - heat transfer. It will come to the aid of those who use wood as firewood for heating. The higher the hardness, i.e. The density of the wood species, the higher its calorific value.
Of course, no one will heat a room with boxwood, but when choosing between linden and pine or birch and acacia, you can get much more heat if you know which of these species is the hardest.
Information about the density of each tree can be gleaned from the tables, since all this information is systematized for ease of use.

Question for experts: Just as accurately as possible plz
Sincerely, For your impudence
Best answers
If you give the steel grade, it will be possible to say reliably with an error of 1-2%. Since the weight of steel of different grades varies. So, ferrous metals differ from stainless steels by 15-20% (again, which brands to compare exactly).
Good luck to you!!!.
Using integrals and differential equations, measure the ax, then weigh it :)
Specific gravity of Iron (pure) 7.86 g.
/cm. cube A total cubic meter will weigh 7,860 kg. All sorts of rubbish is added to steel, but the additives amount to thousandths of iron. Therefore, this value can be considered accurate.
answer
This video will help you figure it out
Answers from experts
7700-7900 kg/m3, in calculations 7850 kg/m3 is usually used.
Depends on what metal! Aluminum - 2.7 t Iron - 7.87 t Steel - 7.85 t Copper - 8.96 t Gold - 19.3 t Lead - 11.34 t
Iridium - 22.65 t
I don’t remember its density, but the formula is: density x 1 = some kg
what metal? Mercury and titanium are different.
well, you know?! depending on what metal! Metals have different densities! For example, 1 meter of lead differs from 1 meter of aluminum by 50 times!
density = mass/volume => mass = density*volume, and weight (at rest) is mass*gravitational acceleration (9.8 m/s2).
the volume of any substance is equal to mass divided by density
Density times volume = mass (multiply in appropriate units). Without density (or at least the name of the metal) it is impossible to answer the question.
I’ll answer you exactly - 1 cubic meter of metal weighs 7800 kg - keep in mind that a meter per meter and with a thickness of one mm weighs 7.8 kg and multiply this by 1000 and you get 7800 kg - this means 7 tons and 800 kg. thank you for your attention
GUYS HOW TO CALCULATE THIS BARREL length 3.5 diameter 2 meters thickness 4 mm
the area of the barrel is equal to the area of the end surface multiplied by the length of the side surface and multiplied by the number P = 3.14
V = 3.14 * a*b*h
Use a tape measure to measure the circumference, you will get the diameter, and then according to the formula, the area of the cylinder.

How much does a cube of concrete weigh?
The use of cement mortar for construction purposes can be found much more often than most other known materials. That is why quite often it is necessary to find out the mass of one cubic meter of the mixture - the weight of finished concrete and reinforced concrete structures plays an important role in the design of structures. Next we will talk about how much a cube of concrete weighs and what affects this characteristic.
Classification by weight
The use of concrete mass has become quite widespread: from finishing purposes to the construction of dams. That is why the characteristics of the mixture are displayed by dividing them into classes and brands. This makes it possible to make precise choices for specific purposes.
For example, B25 grade of concrete is much stronger than B10 and, naturally, its mass will be greater. There is also a division depending on mass.
The table will help you see exactly the weight of concrete in 1m3, but more on that a little later, but for now let’s look at the division by “weight categories”:
- Thermal insulation;
- Easy;
- Heavy;
- Super heavy.
| types | stamps | specific gravity, kg |
| especially light | M50 - M75 | up to 500 |
| lungs | M100 - M200 | 500-1800 |
| heavy | M200 – M400 | 1800-2500 |
| especially heavy | M 450 and above | 2500-3000 |
Weight directly depends on the density of all elements and can be in the range of 300-3000 kg.
Thermal insulation (extra light)
This material is made from cement and fillers, which when mixed, produces a structure with about 85% voids. Used for the manufacture of structures with special requirements for thermal conductivity (they are not able to withstand significant load-bearing loads). This category includes mixtures weighing up to 500 kg per cubic meter. In some cases, a plasticizer for concrete is used to increase their strength.
It is worth considering the low resistance of porous structures to frost. When installing them, it is necessary to install waterproofing protection.
Easy
This is how a solution with a mass in the range of 500-1800 kg is classified. It is mainly used to create special building blocks, the structure of which contains pores - they can be formed with the help of foaming agents or due to the use of cellular fillers (expanded clay, for example).
Only ready-mixed concrete can exactly match the specified weight and grade.
Heavy
Heavy concrete is one of the most common in construction. It is ideal for the construction of structural components that perform a load-bearing function. The weight of the cube in this case can be 1800-2500 kg - this figure depends entirely on the percentage of sand and coarse filler, as well as the density of the latter (even when using granite and gravel filler in the same quantity, the final weight of one cubic meter will be different).
Super heavy (extra heavy)
For its manufacture, metal fillers are used, which increases the weight characteristics to a maximum limit of 1 cubic meter - a little more than 3000 kg. Such mixtures are used to prevent the spread of radioactive radiation through walls.
The production of super-heavy mixtures involves the use of materials quite specific to construction, the cost of which will make the construction of a house quite expensive. That is why they are used exclusively in the construction of objects with increased requirements for radiation protection.
Volumetric weight table
| Cement brand | Liquid state (t/m³) | Dry condition (t/m³) |
| M100 | 2 366 | 2 180 |
| M150 | 2 360 | 2 181 |
| M200 | 2 362 | 2 182 |
| M300 | 2 358 | 2 183 |
| M400 | 2 350 | 2 170 |
| M500 | 2 355 | 2 180 |
If we compare weight indicators in volumetric and specific ratios, it turns out that volumetrically M200 weighs the same as actual concrete M250.
Specific gravity table
Brand of concrete Specific gravity of 1 m3 of concrete| Concrete M100 | 2494 kg |
| Concrete M200 | 2432 kg |
| Concrete M250 | 2348 kg |
| Concrete M300 | 2389 kg |
| Concrete M350 | 2502 kg |
| Concrete M400 | 2376 kg |
| Concrete M500 | 2298 kg |
Now you know how much a cube of concrete of a particular brand weighs. Just keep in mind that it is possible to achieve exact compliance with the characteristics during its factory production.

How much does a cube of steel weigh?
The theoretical mass of a linear meter of rolled sheet metal is calculated based on reference information according to GOST or using a simple geometric formula ρу = ρ a s, (kg/m)
ρ - steel density 7850 kg/m 3
Specific volume is the volume per unit weight of a given substance. Dimension: m 3 / kg The reciprocal of the specific volume is the specific gravity. Dimension: kg/m 3
In addition to the specific volume, the state of the body can be characterized by molar volume = specific volume x μ, where μ is the molecular weight of the substance.
Methods for experimental determination of specific volumes of substances
Various methods are used: a method based on weighing, a pycnometer method, a hydrometer method and others, depending on the state of aggregation of the substance under study, pressure and temperature, as well as the possible conditions of the experiment.
Determination of metal specific gravity
The body under test is first weighed in the air, let its weight be = g1, and then immersed in water.
Due to the loss in weight of the object (according to Archimedes' law), the scale pan to which the body is suspended rises. To bring the scales to the equilibrium position, it is necessary to put some weight - g2. Body specific gravity = g1 : g2
The body under test can have any shape, but it must not be too small (so that, in comparison with its weight, the weight of the thread used for hanging can be neglected).
Example: A piece of high-speed steel weighs g1 = 450 g Additional weight g2 = 55 g
Specific gravity ϒ = g1/g2 = 450/55 = 8.3 g/cm3
Weight of 1 cubic meter (1 m 3, cube, cubic meter) of steel (stainless, acid-resistant, scale-resistant and heat-resistant):
