> *shrug* You have your own way of looking at this.  However, I really did not want to leave someone that is just starting with a long and academic chapter on types in Ada.  It would be boring and discourage someone from learning Ada.

Define a temperature scale for a home thermometer. It has a measurement range from -30 to +40 °C.

Define a type for values you can read from a foldable meter rod (0 to 2 m).
