What are the reasons to not use em units for transform values?

I'm thinking that if you want to maintain transformations in proportion to text and across different viewport sizes, ems would be suitable, wouldn't they? Especially if the transformed item is something like an SVG?

If you set BODY font size like 16px and then YOU SET some size to all other element font sizes with em.

NOW LETS SAY YOU WANT TO MAKE ALL TEXTS SMALLER/BIGGER onmobile/tablet/pc

you only have to change BODY font size and all others scale them self.

EM is like saying MULTIPLY BY

Example 1.5 em = multiply my body font size by 1.5x
(if your body size was 16px then 1.5 em will be 16px * 1,5 = 24px; )
