SwitchExplanation
Formula: REM (16px root) = Millimeters × 0.23622. Why: rem and em are relative units, so this route uses the page's explicit 16px baseline assumption before applying the target unit through CSS pixels.
Millimeters (mm): a metric length unit used for precise print, packaging, and physical-size specifications.
REM (16px root): a CSS relative unit based on the root font size. This converter assumes a fixed 16px root size.
This route is useful when translating between fixed CSS lengths and relative typography units so spacing, font sizing, and responsive UI rules stay on an explicit baseline.
This conversion is purely multiplicative because both units reduce through CSS pixels using a fixed 96 px per inch baseline and explicit relative-unit assumptions where needed.
