Default WordML Unit Measurement ? pixel or point or inches

I created unit converted for openXML https://unit-converter-bcmmybn3dq-ez.a.run.app/

There also a table with formulas for all common office units.

It is something called DXA. There are 1440 DXA per inch. 1 inch is 72 points. 1 DXA is 1/20th's of a point (20 DXA is 1 point). There is also something called EMU's (914400 EMUs is 1 inch, 12700 EMUs is 1pt).

Please don't ask me how I know this. Microsoft ಠ_ಠ
