What is Px to Cm Converter?

Centimeters(cm) are a widely used unit of measurement in everyday life. It is highly demanded in print media, web development, and screen design. This pixels-to-centimeter converter is a free online tool for converting pixels to equivalent centimeters.

How to use the Pixels to Centimeters Converter

Before using the px to cm converter, you must know about PPI and DPI.

PPI stands for Pixels Per Inch, and DPI stands for Dots Per Inch. These two terms are crucial for preparing print designs. Moreover, PPI refers to the density of pixels within one-inch square. On the other hand, DPI refers to the density of ink dots a printer can place within one inch.

If you convert pixels to inches in print media, the standard PPI resolution may be 300 PPI or 150 PPI.

W3C recommends the standard and default PPI of 96 Pixels per inch for web design. In print media, the common print resolution is 300 PPI or higher. In the third case, photo editing software uses PPI to define image resolution.  

Steps to Use the Px to Cm Converter

Here are some steps through which you can understand how to use this pixels to centimeter tool with the correct values:

Step 1: First, set the Pixels Per Inch(PPI). This value depends on your need for conversion, which may be for web, print, or other purposes. All the values are mentioned above.

Step 2: Input the Pixel (PX) Value in the PX input field that you want to convert into centimeters. 

Step 3:  Press the convert button and view the Centimeter (CM) Result instantly.

How to Convert PX to CM: The Formula Explained

If you want to convert px to cm manually, you must have explicit knowledge of the relationship of pixels to inches and centimeters.

According to W3C, the unit equivalents are:

1 inch = 2.54 centimeters 

1 inch = 96 pixels (for web/CSS)

Deriving the Formula:

From these equivalencies, we can relate centimeters and pixels:

2.54 centimeters = 96 pixels

To find out how many centimeters are in one pixel, we divide both sides by 96:

1 pixel = 2.54 centimeters / 96

Thus, the formula becomes:

Centimeters (cm) = Pixels (px) * ( 2.54 / PPI )

cm = px * ( 2.54 / 96 )

Example Calculation:

Let’s convert 258 pixels to centimeters using the web-standard 96 PPI:

Centimeters (cm) = 258px * ( 2.54 / 96 )

Centimeters (cm) ≈ 7cm

Therefore, 258 pixels is approximately equal to 7 centimeters at 96 PPI.

Difference between PX & CM

There are some main differences between these two units:

Pixels are digital units that are used mainly for screen-based media. Conversely, Centimeters are physical units of length used primarily for print media and physical dimensions. Thus, the nature of these two units differ significantly.

Moreover, pixels are not inherently scalable across different screen sizes. However, a pixel’s density may vary, such as a 16px font on one screen being 16px on another. Centimeters are fixed and absolute. A 1 cm line will always be 1cm, regardless of object or context. Thus, its size is constant in physical space.
