Convertitore da US uomo a UK

US Men's shoe sizes follow a scale where size 9 corresponds to a foot length of approximately 27 cm, with each half-size adding about 0.42 cm. The US system is used throughout North America and differs from UK sizes by approximately one full size (US 9 ≈ UK 8). Athletic shoe sizes may vary slightly between brands.

UK shoe sizes are the basis for the US system but offset by approximately one size — UK 8 corresponds to a US Men's 9 and a foot length of about 27 cm. The UK system is used throughout Britain, Ireland, and many Commonwealth countries, and it closely matches the Indian shoe size system.
