This essay is really short and not on nearly as important of an issue as some of my others. However, it still bothers me all the same. Consider this a quick public service announcement: Please stop multiplying by 100 to convert a decimal into a percentage.
Seriously, this is honestly and without exagerration the fourth class I have been in where the professor has informed us that to get a percentage we should multiply by 100. Yes, it annoys me enough that I keep track. And it’s not just Denison, but my high school. …and this.
What’s wrong with this?
Well, .59 * 100 is not 59%, it’s 59, or 5900%. 5900% is not 59%. A conversion should not involve growing by a factor of 100.
What’s the matter?
The problem is that there’s a simple fix — tell people to multiply by 100%. .59 * 100% = .59 or 59%. Works perfectly.
Why are you so neurotic about this?
I don’t know. I don’t think I’m a naturally neurotic person. All the data points you get about my personality from this blog are sample bias anyway. This one just bothers me.
Is this really such a big problem?
No, but my brain isn’t really well equipped to keep track of the scales of problems. For good or for bad, this “multiply by 100″ endemic has a similar irksome-based valence to me as “people are dying from malaria”. This is one reason why I don’t let my philanthropy be dictated by my first-order intuitions about valence.
