If you've ever tried to buy a pair of shoes abroad, you might have noticed the differences in the shoe sizing methods. For example:

• In the UK, the shoe size can be counted with the formula:

  shoe size (barleycorn) = 3 × foot length [in] - 23

• In the United States, you can count the shoe size using the equation:

  shoe size (barleycorn) = 3 × foot length [in] - 22

  for males, and

  shoe size (barleycorn) = 3 × foot length [in] - 21

  for females.

You might notice the barleycorn unit. It's not a grain! 😊 It's equal to exactly 1/3 of an inch.
