AU to JP (cm) Shoe Size for Women

Snapshot

7.5 AU size equals 24.5 JP (cm) size. Conversion Encyclopedia uses the same fixed conversion basis across the calculator, common values, and reverse page for this page.

Reference basis: This result uses the selected cm cohort as the profile basis.
Example: For 5 AU size, the cm cohort returns 22.5 JP (cm) size under the same mapping assumptions.
Use the reverse page if you need the opposite direction with the same basis.

Full API documentation

Explanation

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

For AU size to JP (cm) size, the active cm cohort determines the conversion constants applied to every value.

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.

Common Conversion Values

AU size	JP (cm) size
5	22.5
6.5	23.5

Which shoe-size cohort is used for AU to JP (cm)?

Women sizing is fixed for this shoe-size mapping.

How does this converter compute AU size to JP (cm) size?

The converter applies the formula defined for AU size to JP (cm) size, then renders rounded output for the direct answer and common-value rows.
