How do you calculate the size of a shoe? I know 240 is 38 yards. I completely forgot.

Shoe sizes, also known as shoe sizes, are commonly marked in the following ways: International, European, American and British.

The international standard shoe size indicates the number of millimeters of foot length.

The Chinese standard uses millimeters or centimeters. For example, 245 is the number of millimeters, and 24 1 2 is the number of centimeters, which means the same size.

Conversion formula. Number of centimeters 2 10 = European (European system + 10) 2 = number of centimeters.

Number of centimeters 18+US US +18 centimeters.

Centimeters 18 Imperial Imperial +18+ centimeters.

For example: 240*2-100 10=38

38 yards is 240.

The internationally used shoe size units include European size, American size, and buried millimeters, etc., and 240 is the number of millimeters. The Chinese standard shoe size is mostly measured in millimeters or centimeters, that is, the number of millimeters or centimeters in the stool of the foot length data.

For example, 240 means that it is measured in millimeters, which corresponds to 24 centimeters. We generally say that the number of yards is European yards, which can be based on: the number of centimeters multiplied by 2 minus 10 is equal to the European size, which is converted to 24 2-10 = 38, so 240 is what we usually call 38 yards.

Sizing regulations.

In the late 60s, Chinese mainland formulated the "Chinese shoe size" based on the national measurement of foot length, with length intervals of 1 (1 cm) and width of 1 (narrowest) to 5 (widest).

In 1998, the National Standard of the People's Republic of China based on the MondoPoint system and the millimeter was issued.

GB T3294-1998, known as the "new shoe size"; The shoe size that was previously measured in centimeters is henceforth referred to as the "old shoe size".

In the 21st century, jujube shoes in the Chinese mainland market are required to be marked with new shoe sizes. The conversion formula for the old and new shoe sizes is: new shoe size = (old shoe size + 10) 2.

No, 38 yards is converted to 235.

Conversion of shoe size burial type:

1. The number of centimeters 2-10 = European system, European system +10) 2 = number of centimeters.

For example, the Chinese shoe size is 230 mm, and the size converted to the European system is converted by this formula, and the Chinese shoe size is 235 mm, which is centimeter, yard. It also means that the Chinese shoe size of 235 mm or centimeter is equal to the size of 37 European size.

2. Centimeters - 18 + American, American + centimeters.

The Chinese shoe size is 235 mm, and the conversion to US size is converted using this formula, and the Chinese shoe size is 235 mm, which is centimeters. In other words, a Chinese shoe size of 235 mm or centimeter is equal to a size 6 US size.

Shoe sizes all over the placeEurope. The shoe size of France, Germany and other continental European countries is generally calculated as follows, and the unit is centimeter:

Shoe size = last length = foot length + 2).

However, the exact size may vary slightly depending on the quality of the last.

North America. Shoe sizes in the United States and Canada are last lengths measured in inches

Men's shoe size = 3 * foot length - 22

Women's shoe size (common) = 3 * foot length.

In addition, there is a relatively rare women's shoe size, which was proposed by the Footwear Industries of America

Women's shoe size (FIA) = 3 * foot length - 21

The shoe size for both boys and girls is calculated as the men's shoe size+.

Yes. If the old shoe size is 38 size, the new shoe size (38+10) 2=48 2=24cm=240mm and the new shoe size is 240 size.

It should be noted that the old code and the European code (French code, EU code) in Chinese mainland are fundamentally different and cannot be confused or used interchangeably. Hong Kong, China has always followed the European sizing system, with European yards as the standard unit. The new shoe size in Japan is the same as that in Chinese mainland, using MondoPoint as the standard 5mm base system.

Foot width measurement: Foot circumference refers to the width of the foot and refers to the vertical distance from the ball of the thumb to the base of the tail toe. Gently step on the paper to trace the shape of the outline (the pen is 90 degrees vertical), and then measure the length and width of the foot, and compare the following data table to generally judge the size based on the length of the foot.

If the foot width is smaller than the normal value, it will not have much effect, but if the foot width is higher than the normal value, or if the foot rubber thick version is thicker, it will affect the size as early as a coincidence, and you need to wear a larger size or even a larger size!

It is advisable to measure the size of your feet in the afternoon, as your feet will swell slightly in the afternoon, and the determined size will be most comfortable to wear in the afternoon. The left and right feet of the human body are basically symmetrical, but there must be a slight difference in size, so you should choose the larger one when measuring.

38 shoes should be 240,240 10*2-10=38 sizes, that is, 240 shoes, length 240mm, size 38.

38 shoes are 240. Formula: (shoe size +10) 2 cm, then 38 size:

38+10) 2=24 cm. The Chinese standard uses millimeters or centimeters to measure the size of shoes, that is, the number of millimeters or centimeters of foot length data, such as 38 yards, usually said 240 millimeters, or 24 centimeters, but the actual size of the two is the same.

Shoe precautions

1. The upper of canvas shoes should be cleaned with a neutral cleaning agent, such as laundry detergent and shower gel.

Do not use soap or laundry detergent for toothpaste.

Wait to clean, otherwise the fabric is easy to harden, and it will not be so easy to wear. It is recommended that the laces and upper of canvas shoes can be washed separately.

2. If the upper is white, after washing, you can spread a layer of toilet paper on the upper.

Then put it in the sun to dry, such as selling fiercely. This prevents direct sunlight from turning white shoes yellow, and also prevents the rubber part of the shoe from becoming brittle.

38 yards is 240.

In China's shoe size standards, the foot length is usually converted in millimeters or centimeters, and the corresponding foot length of size 38 shoes can be calculated according to the formula of (38 + 10) 2 = 24 cm, and 24 cm can be converted to get 240 mm, so size 38 shoes represent 240.

If your foot length is 240, you can choose a size 38 shoe; If it is higher than this value, it is best to change to shoes that are one size larger.
