SwitchExplanation
Formula: Millimeters = Inches × 25.4. Why: print-oriented units such as points, picas, inches, centimeters, millimeters, and Q units are normalized through the CSS reference of 96 pixels per inch.
Inches (in): a physical length unit used in print and CSS reference conversions, tied to 96 CSS pixels per inch.
Millimeters (mm): a metric length unit used for precise print, packaging, and physical-size specifications.
This route is useful when comparing print-oriented typography measures across points, picas, millimeters, centimeters, inches, and Q units for editorial and layout work.
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.
