Office 365 Excel change column width to mm

[zillah]

Dear Experts

Attached blank excel sheet column width is read in pixel 8.43 (64 pixel) top of column A I tried File menu --> Option --> Advanced --> Display Ruler to mm --> Press OK button

But that won't change pixel to mm

Am I missing something ? is this the right wait doing it ?
