More Imperial vs. Metric vs. ... Geological?

I was in the health clinic this afternoon and the doctor asked me to step on the scales. She read off "58" and returned to her desk to write it down. Obviously that's in kilograms, not pounds, so I asked if she could convert that measurement for me (I haven't weighed myself in at least 6 months, so I was curious what Ireland has done to me).

Her reply: "Oh of course. That's between 9 and 9 1/2 stones."

I chuckled. "Um, and a stone is...?"

She then laughed and said, "Oh dear, you want me to really convert it, like, into pounds, mathematically??"

So she got out her pen and paper and announced that I weighed 155 pounds.
Whoa, I was certain that was NOT correct. She had no concept of what an average girl of my size would weigh in pounds, hence did not realize that was out of the ballpark for me. I questioned her about this calculation, and her reply was:

"Are you disputing my mathematics??"

I innocently smiled. She recalculated and found that in fact, I weigh 128 pounds. Much more reasonable.

She then asked me what my height is. I replied with 5'8''.
She then stared and said, "Oh dear, you're going to make me do another conversion??"
I then realized that of course, they don't speak of height in terms of feet and inches either, but rather centimeters.

She needed to get my BMI, which turned out to be 20. (Good, acceptable range is somewhere between 19-25.)

She took my blood pressure and then looked at me: "Are you a runner?" Yes. "Your pulse is 51, so I knew you must be fit." Little did she know that I also just briskly walked at least mile in the chilling winter cold and wind...

I got my prescription, took it to the local chemist (pharmacy), and literally within 20 seconds (I timed it), I was out the door with my meds. Gotta love this local community style!
