How it is calculated
Foot length (cm) = (EU - 2) ÷ 1.5, then JP size = foot length (cm), with 1 in = 2.54 cm. The JP size is rounded to the nearest 0.5 cm and the KR and CN size to the nearest 5 mm, following the ISO/TS 19407 formulas.
Example
Inputs: EU size = 42. Result: JP size (cm): 26.5 cm; Exact value before rounding: 26.67 cm; KR and CN size: 265 mm.
