Excel doesn't support any rowheight or any column width. It does it in
increments. There are 72 points to an inch, so you would have to compute
the number of points to a millimeter, then adjust settings to get as close a
possible.

Look at the built-in functions

centimeterstopoints
inchestopoints
pointstoscreenpixelsY
pointstoscreenpixelsX

they may be of some use.
