Pixel to centimeter (cm) conversion is not as straightforward as people may think. This is because there is no set ratio between pixels and centimeters, which means that the number of pixels per cm can vary from screen to screen. In order to calculate this, we need the PPI (pixels per inch), also known as DPI (dots per inch) of the screen or printer. If you do not know your PPI, you can find it here, or you can use 96 which is usually pretty close and will still likely give you an accurate result for this conversion.
pixels at pixels per inch is cm.
