I thought I should post again. I was reminded that on protractors, rulers and thermometers, the number sign is omitted (per Tactile Graphics Guidelines) so it really doesn't matter if they are done in UEB or Nemeth as they can easily be done in either code without changing what appears in braille. If you are in Nemeth already, you can stay in Nemeth. If you are in UEB, you could stay in UEB. Obviously if any of the numbers are decimals, negative numbers, or degrees, they would have to be done in Nemeth. Sorry for the confusion!
