On Friday, one of my co-workers was reading a patient’s chart note and decided to share what she read. This is the conversation that followed:
Her: This poor patient had a 9 mm kidney stone. I just googled a picture of it to see how big it is. That thing is damn near an inch.
Me: 9 mm is almost a centimeter, not an inch. While yes, that would be painful, it’s not even half an inch.
Her: Oh, I see it here next to a dime. The metric system still confuses me.
