Hi,
First, you must know about actual size of your picture in cm.
For example your picture has 1000 pixel of height x 600 pixel of width. You should measure 1000 pixel = ? cm and 600 pixel = ? cm
See this example

You cannot do this by using only information contained in the image, for the same basic reasons I discussed over here
