US UK EUR CM indicates the size code of each country, that is, China is looking at CM, and the United States is looking at US, Britain is looking at UK, and Europe is looking at EUR. The numbers below all represent sizes, and we can buy NIKE in China. EUR indicates the size of 41 yards and 42 yards, which means CM is the length, so sometimes CM needs to be compared. For example, Adidas' 442/3 CHN (the meaning of CM) is 27, which means Nike's 42.5 CM is 27.
