Form size in CM, Points and Pixels ? (1 Viewer)

I'm using a system with 1600*900 native resolution
When I load the forms on systems with lower resolution (LapTops with 1366*768 res) the form become too bit to the screen.

Forms size and objects placement is set in CM
When I develop in VBA I use the points measurements (Or is it Twips?) and use the magic 567 number to convert between the two. This works perfect

I just did a test and changed the resolution of my screen to 1280*720, and the Form seems to keep it size in pixels, not in CM
(Look at the pictures)

Is there a way to convert from this "So called" CM to pixels ?
I mostly want to know what is the biggest form's size I can show on 1366*768
screen.

I use the GetSystemMetrics32 to test the screen resolution

Hi. Not sure if this answers your question but according to this online converter, you are supposed to be able to display a 36 x 20 cm form.
