像素到厘米? [英] Pixel to Centimeter?

我只想知道像素单位是否不变，是否可以将像素转换为厘米?

I just want to know if the pixel unit is something that doesn't change, and if we can convert from pixels to let's say centimeters ?

Similar to this question which asks about points instead of centimeters. There are 72 points per inch and there are 2.54 centimeters per inch, so just substitute 2.54 for 72 in the answer to that question. I'll quote and correct my answer here:

每英寸有2.54厘米；如果足以假设每英寸96像素，则公式很简单:

There are 2.54 centimeters per inch; if it is sufficient to assume 96 pixels per inch, the formula is rather simple:

厘米=像素* 2.54/96

centimeters = pixels * 2.54 / 96

有一种方法称为GetDeviceCaps，用于获取Microsoft Windows显示器每英寸的配置像素. Microsoft有一个名为开发可识别DPI的应用程序"的指南，请查找创建可识别DPI的字体"部分.

There is a way to get the configured pixels per inch of your display for Microsoft Windows called GetDeviceCaps. Microsoft has a guide called "Developing DPI-Aware Applications", look for the section "Creating DPI-Aware Fonts".
