Cm vs Inch

Hi all,
how to switch from px/cm to px/inch ?

When in Resize Mode, select either Width or Height, and next to the out you’ll notice a small arrow icon indicating a drop down menu. This menu is where you will select your preferred unit of measure.

Ok,
it’s clear but I’ll like to select cm for height or width and px/in for Pixel per Unit.
Is it possible ?

The pixel per unit will apply to the unit of measure selected in the output Height/Width.
