Shoe Size Conversion

Shoe size conversion is usually based on foot length or the number of centimeters of foot length. Size standards may vary in different countries and regions, but generally a conversion table or formula is provided to help consumers convert.

Here are some common size conversion methods:

1.International standard shoe size. Usually expressed in millimeters of foot length, such as 123 mm or 12.3 cm, which are actually the same.

2.European shoe size. The shoe size system in continental Europe is the same as that in mainland China, that is, one-third of 2 cm is used as the length of the shoe size. For example, for every 2/3 cm increase in foot length, the shoe size increases by one size. The conversion formula is:

European shoe size = (foot length (cm) ÷ (2/3) + 2.

3.American shoe size. The conversion formula is:

American shoe size = cm - 18 + 0.5.

4.British shoe size. The conversion formula is:

British shoe size = cm - 18.

5.Chinese shoe size. The Chinese standard shoe size is expressed in millimeters or centimeters, and the conversion formula is:

Chinese shoe size = (foot length (cm) × 2-10.

It should be noted that since different brands and styles of shoes may have slight size differences, it is best to try them on or refer to the size chart of a specific brand when buying shoes.

The specific steps are as follows:

1. First, know that the size of the shoe is based on the foot. The length is specified, generally women are 34-37, and men are 38-41.

2. The calculation method of shoe size and centimeters is: shoe length = (shoe size + 10) divided by 2.

3. The minimum adult shoe size is generally 220mm, and the female shoe size is 34, and the shoe size will increase by one size for every 5 mm increase.

1. The Chinese standard uses millimeters or centimeters as units to measure the size of shoes, that is, the millimeters or centimeters of the foot length data.

For example, 235 means that it is in millimeters, corresponding to 23.5 centimeters, and the actual sizes of the two are the same.

2. Shoe size conversion formula:

① Centimeters × 2-10 = European system , (European + 10) ÷ 2 = centimeters.

For example, if the Chinese shoe size is 230 mm, this formula is used to convert it to the European size. The Chinese shoe size is 235 mm, which is 23.5 cm, 23.5*2-10=37 yards. That is to say, the Chinese shoe size of 235 mm or 23.5 cm is equal to the European size of 37 yards.

② Centimeters - 18 + 0.5 = US, US + 18-0.5 = centimeters.

The Chinese shoe size is 235 mm, and this formula is used to convert it to the US size. The Chinese shoe size is 235 mm, which is 23.5 cm, 23.5-18 + 0.5 = 6. That is to say, the Chinese shoe size of 235 mm or 23.5 cm is equal to the US size of 6 yards.

③ Centimeters - 18 = British , British + 18 = centimeters.

The Chinese shoe size is 235 mm, and this formula is used to convert it to the British size. The Chinese shoe size is 235 mm, which is 23.5 cm, 23.5-18=5.5, which means that the Chinese shoe size is 235 mm or 23.5 cm, which is equal to the US size of 5.5.

Foot length measurement precautions:

1. During the measurement process, users should try not to tiptoe, because the human foot will change under different forces; it is also best to keep the body upright, so that our weight can be evenly distributed on both feet, and the data obtained will be accurate.

2. Sometimes there may be deviations in the size of the left and right feet. At this time, it is best to use the length of the larger foot as the basis for selecting the shoe size.

3. It is recommended to measure the size of the foot in the afternoon. Because the foot will swell slightly in the afternoon, it is more appropriate to use the data obtained at this time as the size basis.
