The accessibility impact is probably that you need to programatically
associate any external unit indicator (be it static text or a dropdown)
with the text field, so that screenreaders will present the value and
the unit to users as somewhat of a single entity, rather than as
unrelated controls.

Since the text box will most likely have a descriptive label as well,
this will often mean associating at least two other controls with the
same text box, which isn't technically-challenging for our screenreaders
to handle AFAIK, but I'd imagine it can't help but add a little
complexity to the task for the user.

Cheeri,
Calum.
