📏 What measure do you want to convert to?

I want to convert 12 US sneakers size to:

Systems that are used in the United States 🇺🇸.

The most common is the customary, described in more detail below, which for men's shoes is one size shorter than the UK equivalent, making a men's 13 in the US the same size as a men's 12 in the UK.

• The US traditional system is similar to British sizes but starts counting at one rather than zero, so equivalent sizes are one greater.
• Female sneakers size (barleycorns) = 3 × last length (in) − 23 ≈ 3 × foot length (in) − 21. (where barleycorn is 1⁄3 inch)
• Considering to "standard" or "FIA" (Footwear Industries of America) scale, women's sizes are men's sizes plus 1 (so a women's 12 us is a men's 11 us)
• There is also the "common" scale, where women's sizes are equal to men's sizes plus 1.5.
• In the United States and Canada, there are different systems that are used concurrently.
