Reference

How typography and screen length conversion works

A CSS pixel is defined here as 1/96 inch, matching the web reference pixel convention. Physical device pixels depend on actual pixel density, so the assumption is displayed in every result.

Values are converted to inch first, then from that reference into the requested unit. Keeping a single documented reference reduces inconsistent pair-by-pair constants.

Accuracy note: Pixel conversions assume 96 pixels per inch. Use actual device or print PPI when physical pixel size matters.
