Explanation

CN converts to JP (cm) by first mapping CN to millimeters, then mapping millimeters to JP (cm). Cohort profile fixed: Kids.

CN size to JP (cm) size is cohort-bound here: the selected cm cohort controls the mapping used by calculator and reference table.

Keep the same cohort in both directions to avoid mixing shoe-size systems that use different wearer-group mappings.

Method & Size Mapping

  • Model basis: output depends on the selected shoe-size cohort and follows the same cohort mapping in both directions.
  • Profile reference: cm cohort.
  • Consistency rule: calculator output and table values keep the same shoe-size cohort in both directions.
