JP (cm) to Mondopoint (mm) Shoe Size for Kids

Snapshot

20 JP (cm) size equals 200 Mondopoint (mm) 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 mm cohort as the profile basis.
Example: For 18 JP (cm) size, the mm cohort returns 180 Mondopoint (mm) size under the same mapping assumptions.
Use the reverse page if you need the opposite direction with the same basis.

Full API documentation

Explanation

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

JP (cm) size to Mondopoint (mm) size is cohort-bound here: the selected mm 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: mm cohort.
Consistency rule: calculator output and table values keep the same shoe-size cohort in both directions.

Common Conversion Values

JP (cm) size	Mondopoint (mm) size
