One of the hardest things for new physics students to get used to is the fact that most physics professors seem to be obsessed with units of measurement. The reason for this is simple - if you don’t mention the units you’re using, your statements will usually have no content. For example, if a friend is traveling around the world and tells you that his hotel room was “4,000”, that means nothing. If it was 4,000 US dollars, it must have been a nice room. If it’s 4,000 lira or 4,000 yen, it might have been a phone booth.
