You can resize a figure containing an image of a given pixel size so it could map to any size.

You really can't, unless you have some specification for how many pixels/cm your print or display is supposed to be.
For example, if you are making a GUI and you need to determine its size and/or position on a display, the uicontrol() option 'position' is specified as:
Pixels.
Starting in R2015b, distances in pixels are independent of your system resolution on
Windows® and Macintosh systems:
On Windows systems, a pixel is 1/96th of an inch.
On Macintosh systems, a pixel is 1/72nd of an inch.
On Linux® systems, the size of a pixel is determined by your system resolution.
Here, if you're trying to do a pixels -> inches conversion, you have a conversion standard.
There needs to be some sort of metric by which you're using to convert pixels to a physical measurement.
