在CSS中将“mm”缩放为“像素” [英] Scale 'mm' to 'pixels' in CSS
问题描述
我有一个容器,每个测量都以'mm'定义,以用于打印目的。但是,我想在一个600px宽的块中展示它的预览,完美契合。将其缩小的最佳方法是什么?
I have a container with every measurement defined in 'mm' for printing purposes. However, I want to show its preview inside a 600px wide block with perfect fit. What would be the best way to scale it down?
推荐答案
毫米至像素以及反之亦然公式考虑了屏幕的
The millimiter to pixels and vice-versa formula takes the DPI of the screen into consideration.
DPI意味着每英寸点数。
毫米级像素没有真相除非你有一个稳定的DPI值,你可以使用。
There's no truth in mm to pixels unless you have a stable DPI value you can use.
无论如何,这是公式:
mm =(pixels * 25.4)/ dpi
mm = (pixels * 25.4) / dpi
最常见的DPI如果我没有弄错的话,看到的值是72和96,但由于这是用于打印,它很可能取决于打印机设置
The most-usual seen DPI values seen are 72 and 96 if I'm not mistaken, but since this is for print it will most likely depend on the printer settings
