Formula Used
- Men: anchor pairs (US→EU): 6→39, 7→40, 8→41, 9→42, 10→43, 11→44, 12→45, 13→46. Between anchors, EU ≈ EUlow + (US−USlow)×slope, where slope is the segment’s EU/US change (≈1 per US size).
- Women: anchor pairs (US→EU): 5→35.5, 6→37, 7→38, 8→39, 9→40, 10→41, 11→42. Same interpolation logic; practical rule of thumb ≈ US + 31.
- Unisex: applies the men mapping.
- Outputs are rounded to the nearest 0.5 EU, with min/max guards.
