Conversion tables for inch to metric sizes. Thread size: table of metric and inch threads

The process of selecting the required cross-sectional sizes of threads, cables and pipes often takes a lot of time. In addition to the fact that it is necessary to select the appropriate dimensions, taking into account the parameters of the equipment, the customer has to independently convert the data into suitable units of measurement. This process requires significant time.

We simplify this task because we invite you to use ready-made translation tables. On the page of our website you will find tables that will help you easily select the necessary threads for inch pipes, copper and aluminum wires and cables. Also, you can use the table for converting inch dimensions to metric ones, thereby accurately calculating the required section dimensions.

Unfortunately, most equipment manufacturers leave the customer alone with the calculations. Therefore, a person has to independently search for conversion tables on the Internet in order to select the optimal sizes of wire cross-sections and pipe diameters.

We value the time of our clients, providing everyone with the opportunity to use ready-made solutions. Our tables convert standard sizes from inches to millimeters.

On this page you will also find translations of the main energy units and pressure units, therefore, you will be able to choose the right refrigeration equipment, taking into account the individual placement conditions and operating modes of the units.

A very common question among users of foreign stores is whether the seller made a mistake, and if not, what does one size mean on Aliexpress?

No, this is not the seller’s mistake, he did everything right.

The thing is that in China, when sewing some products, they are not divided into size grids, but are sewn into one size that suits everyone.

These parameters are called differently: One Size, one size, one size, universal.

Why only this?

Items that have undergone changes in format are made from elastic, pliable materials. And these are also those things that, thanks to their open design and cut, can fit more than just one size.

This eliminates the need to sew a bunch of things with different volumes; you can sew a product that is similar in parameters to all its copies.

What things are universal?

The following are often created with a universal size:

• Leggings;
• Mikey;
• Socks and stockings;
• Robes;
• Scarves;
• Some types of dresses;
• Loose fit cardigans;
• Carnival costumes and overalls.

Who can afford One Size?

No matter how elastic the fabric is, unfortunately for some, it cannot become rubber. Even this fabric has its limits.

Yes, it really can fit the owners of several adjacent sizes in the grid, but it will not be able to accommodate the owner of a considerable 3 or 4XL.

Things created in China are designed for its inhabitants. And since even residents with XL dimensions are very rare, Chinese seamstresses don’t even think about larger sizes. Things would gather dust without much demand.

So what size does Aliexpress mean when they say one size?

You can include it here:

• owners of clothing sizes 40-46 or S-M (L);
• Those whose height is not less than 155 centimeters and not more than 175 centimeters;
• The approximate weight of such people ranges from 45 to 65-70 kilograms.

But, there is one nuance: sellers from Asian countries, having a miniature build and short stature, can and actually measure the parameters of their own body, which in the end, for a Russian person, can turn into a small thing.

How can a Russian person understand the boundaries of the phrase “one size” on Aliexpress?

To avoid conflicts and open disputes, you must carefully read the description of a particular product; usually, when indicating the “Universal” value, the merchant describes what parameters it may fit. Or, in extreme cases, he will simply write centimeters from and to. Here, for example, the description tells about who can order a dress:

The example clearly shows that the “immense” universal volume ended at a waist of 80 cm and a bust of 96.

Tricks

Another reason why you need to discuss all the details of the order with the seller is cunning and the desire to sell the product quickly.

Some sellers mark the size of the items they offer as universal, one-size-fits-all, which means they fit more than just one size. But in reality, this is only one size, just one remaining from the size range, or things are initially produced in one size.

Like any other products in this group, these will be designated with the hashtags “One Size”, “single size”, “one size”, “universal”, “free”. And when you find them in the search results list, of course, pay attention to them. You can look at the item in the pictures without consequences, but it’s unlikely to place an order.

The discussion will help you find out the parameters in centimeters of these products if they are not in the description.

Be careful, do not accept the field where one size is indicated (free) with the free delivery field (also free). In a situation where you were not vigilant, opening a dispute is useless.

P.S. Friends, when shopping in online stores, be sure to use. As they say, if you save, you earn it!

With this I want to say goodbye to you, happy shopping everyone!

Knowing your breast size is as important for any woman as knowing your dress or jeans size. And even more important, because the right one always gives special confidence. Determining the size is very simple, and it is advisable to do it at home, so that in the lingerie store you do not have to try on all the sets available there.

The easy way: just two parameters

Experts advise determining breast size in different ways: some say that you need to be completely undressed, others allow the presence of a light bra (without push-up). If you wish, you can choose any method, since the difference in performance will be minimal.

You only need to take two measurements, for which you need a metric tape, also called “centimeter”. They need to measure the volume of the chest, stretching it under the shoulder blades, through the armpits and the nipple line. The second parameter is even easier to calculate - with the same centimeter you need to measure the volume of the torso under the chest. In this case, it is advisable to stand straight and try to relax, and be sure to exhale.

The result will be two numbers. From the larger one (chest girth) you need to subtract the smaller one (underbust girth) - a simple problem. And then just check the small table.

Using this table is also easy. For example, if the volume under the bust is 92 cm, and the volume along its protruding part is 112 cm, then the fullness of the cup will be C, and accordingly there will be a number 90 in front of it. For most European manufacturers, the volume under the bust usually differs by five units and starts at 60. So on bras it will be 60, 65, 70, 75, 80, 85, etc.

Subtle tricks

Arriving at the store, even after carefully studying their parameters and determining sizes using tables, women may experience unexpected surprises. It seems that the customer is wearing a 75B bra, but in the boutique a 70D bra fits her perfectly. Accident or mistake? This is the so-called parallel dimension, when two bras can fit at the same time, completely matching in all respects. But usually the fair sex knows only one size, because good stores always have the necessary tables and a consultant will help you use them. There are advantages to parallel sizes: if the requested size is not available, you can always select its “analogue”.

Also, sometimes there are markings on bras that completely match the sizes of dresses or blouses. And it is indicated in Latin letters (XS, S, M, L, XL) or a number, where the size coincides with the European clothing size - 32, 34, 36, 38, etc. If it needs to be “correlated” with the Russian one, it is worth adding six units. So, European size 32 corresponds to Russian 38, and size 40 corresponds to 46. But even in this case, difficulties when buying lingerie usually do not arise, since sellers always know the volumes of women’s figures that correspond to these sizes.

Sometimes it happens that a woman’s wardrobe contains bras of different sizes, and they cannot be called parallel. Sometimes the comfort of a bra depends not only on a certain size, but also on the model. For example, bras from the same manufacturer, but completely different models, can look completely different on the same woman. And either size 75B, 70B, or even 80B can suit her. This shouldn’t be too surprising, because the main thing is a feeling of comfort, so sometimes you can use the fitting once again.

How to choose a bra as a gift

Firstly, this way you won’t have to explain for a long time to the seller who their chosen one is like. And secondly, she will probably be satisfied. Moreover, both beautiful lingerie and an understanding of how well the loved one knows her. And even if it’s awkward to ask a woman directly about her size, you can always look at the markings on her bra. And only then go to the store for such an exciting and luxurious gift.

– we’ll look at it in the next article.

Are you planning to go shopping? Shopping, buying new things, changing your style and image is certainly an exciting and interesting activity. However, the unclear letters that indicate sizes S M and L, xl, xxl can cause some confusion in the process of buying something you like if you don’t know what they mean.

How to determine clothing size

We are accustomed to thinking that the main indicator for determining size is half the chest circumference. It is important to take measurements correctly. The measuring tape should be positioned exactly horizontally, adhere tightly to the body without much tension or sagging, and pass through the most prominent points of the chest.

The person being measured must be wearing underwear or light summer clothing. In order to make the decoding of sizes S M L as accurate as possible, we recommend taking additional measurements:

chest girth;

waist circumference;

hip girth.

We measure the waist on a naked body, without retracting or protruding the stomach; the body position should be relaxed and natural. We measure the hips at their widest point.

Keep in mind that if your body type, for example, fits T-shirt sizes S M L, this does not mean that skirts or trousers will have the same size.

Correspondence of letter designations with numbers

There are several generally accepted size markings: Russian, European and American. The international letter designation system is usually used.

In order to decide what sizes S M L are, let’s say right away that the letter designation represents the first letter of the corresponding English word:

S – Small (small);

M – Middle;

L- Large (large).

The letter X (extra) can mean very small (XS) or, on the contrary, very large (HL).

For women

To determine S M L what sizes these are in the Russian manner of designating the size range, it is better to use a special table. The standard European size chart for women's clothing translated into Russian size S M L is as follows:

S – corresponds to 44;

M – for PoH value 46 cm;

L – means Russian 48.

For men

The table of clothing sizes S M L for men has a similar appearance. The principle for determining men's metric values ​​is the same as for women's clothing:

S – corresponds to the 46th;

L – means 50.

The size of men's clothing S M L, unlike women's, includes such an indicator as neck circumference. It is important when choosing and purchasing dress shirts.

For those who find it easier to navigate the usual size grid, using tables they can easily convert European designations into women's Russian sizes S M L.

How not to make a mistake when choosing clothes

Despite the fact that there is a generally accepted table of sizes S M L, the size of clothing from different manufacturers can vary significantly. Sometimes it happens that the winter collection will be more complete than the summer collection from the same brand. Please note that a product may be manufactured for a specific country's market, which may use a different metric system.

To be sure, it is better to use not average data, but size tables of the brand whose clothes you are going to buy. This information can usually be found on the manufacturer's website.

The surest way to avoid making mistakes when buying clothes is to try on the item in a brand store. If you plan to purchase clothes in an online store, then the right thing to do is to visit a real retail outlet and try on several items of the chosen brand.

If you summarize the data, you will get a summary table of the correspondence between the size range of women's and men's clothing.

Sometimes it is not always possible to depict a part on a drawing document in full size. The greatest difficulties are caused by the construction of volumetric parts with large dimensions that go beyond the A1 and A0 formats. Specialists often use a 2 to 1 scale in their work. How’s that? Everything is very simple - you need to proportionally increase all the dimensions of a part or any mechanism by 2 times so that they are better visible on the sheet.

What is scaling?

To construct any drawings, the Unified System of Design Documentation is used as a basis, which describes not only the principles of scaling, but also the rules for arranging parts in the drawing, applying dimensions, shading, and filling out the main inscription.

The word “scaling” itself is taken from the German language and means in the original translation “size, measurement”. Scales are used to depict large products - aircraft parts, structural elements of residential and public buildings, etc., as well as to enlarge small parts - the mechanism of a wristwatch.

M 1:1 is the actual size of the drawn part, and 1:2 is a reduction in the size of the part by 2 times so that it fits on a sheet of a certain format.

A scale of 2 to 1 is like a visual increase in the natural dimensions of the product by 2 times, so that the designer in production can understand more clearly what the finished part should look like.

The drawing standard from 1968 gives an idea of ​​the existing scales and methods of their construction: 1:1; 1:75; 1:500; 1:1000; 100:1; 4:1; 2:1.

The 2 to 1 scale is like the smallest of all magnification scales.

How to build a part?

To depict elements in a drawing, you need to know or measure their linear dimensions, then multiply them all by two and make a drawing using twice the dimensions. It is important to remember that there is no need to increase or decrease the size of the corners and the radii of the roundings!

When applying dimensions after constructing a drawing, the natural linear dimensions of the parts are indicated. In order for the designer to understand that the part was intentionally enlarged by 2 times, it is necessary to indicate “scale 2 to 1” in the drawing. This is indicated in the “Title Block” table in the “Scale” section.

If in the drawing only individual elements were enlarged 2 times, then above the image of these elements they write “scale 2 to 1” - this is like an enlargement of the selected object (see in the figure above).
