如何从像素转换为Cm或Mm? [英] How to convert from pixels to Cm or Mm?

问题描述

海佬..
我将白色像素算作区域检测，例如2500像素.我尝试使用此公式将像素转换为Cm:

区域检测(cm)= 1/像素区域检测* 2.54

但是结果表明每个像素的大小，这不是我所需要的.
我需要的是将以像素为单位的区域检测大小转换为Cm或Mm.
那么，如何将区域检测的大小从像素转换为Cm或Mm?
谢谢..::

Hai guys..
I was count white pixels as an area detection, for example 2500 pixels. I was tried using this formula to convert pixels to Cm :

area detection (cm) = 1 / pixels area detection * 2.54

But the result indicate the size of each pixels and it isn''t what i need.
What i need is to convert size of area detection in pixels to Cm or Mm.
So, how to convert size of area detection from pixels to Cm or Mm?
Thank you.. :)
