If you have multiple measurements of the same sort of thing, then they
will usually have the same scales - unless you have a really weird
design.  (Sometimes you do a bit of shifting in order to make a system a
little independent of the hardware - you might shift your 0..1023 input
from a 10-bit ADC by 2, to get a 0..4095 range, so that you can later
use a 12-bit ADC for more accuracy.)

If you have multiple different types of measurements, then there is no
issue with consistency - no one expects a temperature measurement to
have the same scaling as a current measurement.

I certainly agree that there are occasions where moving to floating
point and/or SI units (you can use SI units without floating point -
such as holding your voltage as an integer number of millivolts) can be
useful in simplifying the logic of the code.  But is the exception, not
the rule.

No on both counts.  Please re-read the posts.

It completely contradicts what you have been saying, making it a
revelation to you (though not to anyone who actually does embedded
programming).

Yes - but embedded programmers have developed techniques such as naming
variables, using types, comments, and documentation as a way of handling
this complexity.  It means we don't have to turn everything into
floating point and assume it is all scaled as 0 .. 1.0.
