Formula and Logic
This tool uses standard international shoe size conversion charts. For example, US men's size 9 is approximately UK size 8 and EU size 42.
Conversions are based on linear offsets for each region pair, adjusted for half sizes where applicable.
Japanese sizes are derived from foot length in centimeters, so the tool calculates an approximate millimeter value for reference.

Shoe sizes can vary by brand and style, so always check the manufacturer's size guide when shopping online.
For athletic shoes, consider sizing up for extra room, especially if you have wide feet.
When traveling, knowing your size in the local region can save time and avoid returns.
Common unit conversion: 1 inch = 25.4 mm, which is used for Japanese size calculations.
