Complete Guide: PX to CM Converter
Everything you need to know about using this tool effectively
The PX to CM Converter transforms pixel measurements to centimeters using a configurable DPI (dots per inch) value. The standard screen DPI is 96, which means 96 pixels equal 1 inch (2.54 cm). For print, 300 DPI is common. The tool accepts any DPI value and converts instantly. All processing happens in the browser.
This tool applies the formula: cm = px / DPI × 2.54. You enter the pixel value and set the DPI, and the tool calculates the centimeter equivalent.

96 DPI is the standard web/screen resolution.
300 DPI is the standard for print-quality output.
The formula is cm = px / DPI × 2.54.
Different devices have different actual DPI values.
What is DPI?
DPI (dots per inch) is the number of pixels that fit in one inch. Higher DPI means more pixels per inch, resulting in finer detail.
Is my data sent to a server?
No. All conversion happens in your browser. Nothing is transmitted.
What DPI should I use?
96 for screen/web design. 300 for print. 72 for older Mac systems.
Can I convert cm to px?
Yes. The tool works in both directions.
Why do different DPI values give different results?
DPI determines how many pixels fit in an inch. At 96 DPI, 96 pixels = 1 inch = 2.54 cm. At 300 DPI, 300 pixels = 1 inch = 2.54 cm.
