I'm not really sure how to explain what I stated earlier any clearer. I've never been any good at describing things, but I'll give it another try.

What I was trying to state is that, at points, one may not always equal one because the units that we measure things in are not constant.

(Is => how you would state that things are not equal in regular mathematics? All that I have ever seen was the equal sign with the slash or the equal sign with the question mark over it to mean questionable. Since I couldn't type either of those with my computer I borrowed '!=' from code, because '!' means not. Sorry if that isn't the way you write it on a computer...)
