The point of the example was to demonstrate descriptive names. For
local variables I usually wouldn't bother with the units, but in
general it's a good practice to help avoid crashing your orbiter into
Mars.

To me, the use of the standard name implies standard units, so no, "G"
is sufficient. YMMV.
