Convert PX to CM

Quick question

How convert PX to CM ?

var doc = activeDocument;
var artLayer = activeDocument.activeLayer;
var textItem = artLayer.textItem;
textItem.kind = TextType.PARAGRAPHTEXT;
var textWidth = textItem.width.as("px"); 
var textHeight = textItem.height.as("px"); 
alert(textWidth+"_"+textHeight);

textItem.width.as("cm");  ----> It does not show the correct value and the value is different depending on the resolution.

I believe you need to set the units for everything to what ever you want to use:

app.preferences.rulerUnits = Units.PIXELS;

I found a solution

var LB = activeDocument.activeLayer.bounds;
var width = LB[2].as("cm") - LB[0].as("cm");
alert(width);

This is not true.
Just like almost always lying textItem.width and textItem.height

My point was that I found a way to solve my problem differently.

I wanted to know the width of the text in centimeters and now I know.

If I mislead you, I apologize;) Of course, textItem.width is still useless.
