Various shoe sizing methods

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.
