Thanks for the comment, Ibendlin.   I do agree, and do subscribe, to
"Less is more".

As this is not an appropriate venue to discuss the development process
of my app, let me just briefly outline how it went with regard to the
button:
1. The elimination of "km/h" was considered and rejected as the
button's function could change to adapt to the use context (e.g.
"mph", "seconds", "km", etc. as I stated in the previous post)
2. Changing of button and font color according to the function, was
prototyped (without "km/h") and rejected as it gets so confusing.
3. Placement of "km/h" outside of the button, right next to it, was
considered and rejected for the likeliness of the button becoming too
small in the available space.
4. Alternating display of "34.5" and "km/h" was considered and
rejected because it forces user to wait in obtaining timing sensitive
info.
5. The use of audio (to indicate the figure displayed is in "km/h")
was considered, but audio is needed for another function, and the use
scenario cannot eliminate the simultaneous use of the two functions.

I am all ears if you could come up with a better idea, but the desire
to have large "23.4" and small "km/h" did not come that lightly.
Moreover, I love the challenge and the satisfaction in solving
problems and limitations, which came much quicker than I anticipated
in this case thanks to Mark Murphy and Zsolt Vasvari.
