How many centimeters does 1 pixel equal?

1cm contains 25 pixels.

The unit of pixel is "one" and centimeter is the unit of length. One centimeter is not equal to how many pixels, only one centimeter contains how many pixels.

For example, for a display, the dot pitch is 0.28mm, so how many pixels there are in one centimeter can be calculated.

How many pixels a centimeter contains depends on the specific device.

A pixel refers to a small square of an image, called a pixel. These small squares have definite positions and assigned color values, and the color and position of these small squares determine the appearance of the image.

Pixel can be regarded as an inseparable unit or element in the whole image, that is to say, it cannot be cut into smaller units or elements, and it exists as a single color unit. Each dot matrix image contains a certain number of pixels, which determine the size of the image on the screen.

Extended data:

Several other concepts, such as voxel, texture element and surface element, are all derived from the concept of pixel and used in other computer graphics and image processing applications.

Dots are sometimes used to represent pixels, especially for computer marketers, and most of the time they are represented by DPI (dots per inch).

When the picture size is in pixels, we need to specify its fixed resolution in order to convert the picture size into the actual size in reality. For example, the resolution of the most commonly used pictures in web pages is 72, that is, 7265438 pixels per inch +0 inch equals 2.54 cm, then it can be concluded that each cm equals 28 pixels through conversion; Another example is a picture with the length of 15x 15cm, which is equal to the length of 420*420 pixels.
