A pixel usually has a known size, and there are many ways to figure it out.
If it is a printed pixel, then it probably has a resolution of 300 or 600 dpi (or higher!), where dpi = dots per inch. So a 300 dpi pixel = 1/300 inches. To convert inches to centimeters, multiply by 2.54.
So... a 300 dpi pixel = 1/300 inches = 1/300*2.54 cm = 0.00847 cm
For a computer monitor pixel, if you don't know your monitor's dpi, you can measure the width of your screen in centimeters (for example, mine is 40 cm wide... be careful, most monitors are sold using a diagonal dimension). Then, figure out the maximum horizontal resolution of the monitor (look in your user guide if you don't know, but for example, let's say 1600 pixels). The pixel size is then (40/1600) cm = 0.025 cm

BeauIn truth, you don't convert pixels to cm. There is a little more information that is needed and without knowing exactly what it is that you want to do, it is difficult to address this completely. There is a de facto norm of 300 DPI /PPI for printing (that is 300 / 2.54 pixels/cm).
A pixel is one of the colored dots on your computer screen that makes up both images and text (as well as all of the blank areas in between them). Most computer screens display either 72 or 96 pixels per inch. Most printing is based on 300 pixels per inch (rarely 240 PPI).
If you are asking about printing: If you want to make a 4 x 6 inch print on a 300 DPI (Dot Per Inch) printer you need your file to contain 1200 x 1800 pixels. An 8 x10 printout will have to be 2400 x 3000 pixels. In reality, most consumer printing systems will handle this conversion for you. You just tell the software what size print you want to make the software will "re size" your image to the correct dimensions.

How much is 300 x 186 pixels in cm?
To convert pixels to centimeters, you need to know the pixel density (or PPI) of the screen. Without that information, it's not possible to accurately convert 300 x 186 pixels to centimeters.
What size is 1600 picture in cm?
The size of a 1600 picture will depend on the resolution of the image. For example, if it is 1600 pixels wide by 1200 pixels high (common for a 4:3 aspect ratio image), the size in centimeters will be influenced by the pixel density or dots per inch (DPI) when printed. Without knowing the DPI, it's not possible to provide an exact size in centimeters.
How many inches equals 250 pixels?
It depends on the resolution of the device. For a standard 96 pixels per inch resolution, 250 pixels would be approximately 2.6 inches.
What are the tiny dots visible on photo images called?
The tiny dots that are visible on photo images are called pixels. There are generally thousands of pixels in a small area of a photograph. The larger the number of pixels in a small area, the clearer the photograph appears.
What video-related term refers to the number of pixels on the display?
Resolution. It determines the clarity and detail of the image on the screen. It is often represented by two numbers, such as 1920x1080, where the first number refers to the horizontal pixels and the second number refers to the vertical pixels.
