CM to PX: How the Conversion Works
Converting centimeters to pixels translates a physical, metric measurement into digital design units. Since the CSS standard fixes 1 inch at 96px, and 1 inch equals 2.54cm, each centimeter works out to approximately 37.8 pixels.
This conversion is especially useful when working from metric print specifications, packaging dimensions, or European paper sizes and needing to reproduce them accurately in a web layout or design tool.
For example, a 15cm × 21cm A5 page equals roughly 567px × 794px at 96 DPI. A 5cm icon equals about 189px.
