Pixels to Centimeters Converter (PX to CM)

A centimeter (cm) is a widely used unit of measurement in both the physical world and digital media, including web design and screen displays.

Use this Pixels to Centimeters Converter to quickly and accurately convert pixels (px) to centimeters (cm) for precise design adjustments.

Before You Use the Pixels to Centimeters Converter

If you're using the Pixels to Centimeters Converter, you likely need precise measurements for printing designs or editing images. Understanding DPI (dots per inch) and PPI (pixels per inch) is essential for accuracy.

• Understanding PPI vs. DPI

  PPI (Pixels Per Inch): Measures image resolution. For example, a 25cm × 25cm image at 300 PPI has better print quality than one at 96 PPI.

  DPI (Dots Per Inch): Refers to printed dots per inch on an output device (e.g., printer). Generally, 1px = 1 dot in printing.

• How Pixels Convert to Centimeters in Web Design

  For web and CSS measurements, the W3C standard states that 1 cm = 96px / 2.54:

  96px is the default PPI for web.

  2.54 cm = 1 inch, making this the standard conversion.

  The converter is optimized for web-based conversions, with a default PPI of 96. For print media, adjust the PPI/DPI setting to match the target resolution.

Steps to Use the Converter:

• Enter the PPI value.
• Input the Pixels value.
• Click the Convert button.

How to Convert Pixels to Centimeters

Pixel-to-centimeter conversion is crucial for web design, CSS styling, and print media. According to the World Wide Web Consortium (W3C), here are the standard unit conversions:

• Standard Pixel to Centimeter Conversion

  Unit	Equivalence
  Centimeters	1cm = 96px / 2.54
  Inches	1in = 2.54cm = 96px
  Pixels	1px = 1/96th of 1 inch

• Why Does 1 Inch = 96 Pixels in Web Design?

  In web development and CSS, 1 inch is defined as 96 pixels, based on the standard Pixels Per Inch (PPI) ratio. However, in print media, PPI varies depending on the resolution of the printed output.

• Deriving the Pixels to Centimeters Formula

  From the standard conversion:

  1cm = 96px / 2.54

  Rearranging the formula:

  1cm × 2.54 = 96px 
  1px = 2.54cm / 96 
  1px = 2.54cm / PPI

• Pixels to Centimeters Conversion Formula

  To manually convert pixels to centimeters, use the following formula:

  Centimeters = Pixels × (2.54 / PPI)

  Note: For web design or CSS, the default PPI is 96. For print media, adjust the PPI based on your target resolution.
