My Window XP-regional-setting's measurement unit is already set at cm.

From the EXCEL HELP MENU
Unlike Microsoft Word, Excel does not provide a horizontal or vertical
ruler, and there is no quick way to measure the width or height of a
worksheet in inches. Excel uses characters, points, and pixels as units
of measurement.

The width of cells is displayed in characters and pixels rather than in
inches. When you drag the boundary of a column heading to adjust the
width of a column on the worksheet, a ScreenTip displays the width in
characters and shows pixels in parentheses.
The height of cells is displayed in points and pixels rather than in
inches. When you drag the boundary of a row heading to adjust the
height of a row on the worksheet, a ScreenTip displays the height in
points and shows pixels in parentheses.
An approximate conversion of points and pixels to inches is shown in
the following table.

Points Pixels Inches
18 24 .25
36 48 .5
72 96 1
108 144 1.5
144 192 2
