Katie and I were heading to the store.

Katie:  Maybe I should have worn more layers.

Me:  Yeah, it is cold.  The car says it is 40, but it feels more like 32.

Katie (Checking the weather on her phone):  This says it feels like 31 so you are close.

Me:  I knew it felt like it was freezing out there.

Katie:  In Celsius it is 4 degrees, but feels like -1.

Me:  I don’t think in Celsius, but it does feel like it is -1.

Katie:  I had to get used to using Celsius when I was telling people from other countries what the temperature was, so I am used to it.  I think our generation will be the one that changes us over to the metric system.

Me:  I don’t think that will happen, we were told the same thing when we were young.

Katie:  Yeah, but we were taught the metric system in school.

Me:  So were we.

Katie:  Well, in science class, we only used the metric system, so we were more immersed in it.

Me:  That is the same for us.  We used only the metric system in science as well.

Katie:  I thought the Challenger blowing up was much later.

Me:  What does that have to do with anything?

Katie:  They forgot to convert something into metric and that caused it to blow up.

Me:  It was an O-ring that caused the shuttle to blow up.  That is like a rubber washer and that happened when I was in school.

Katie (looking on her phone):  Oh it was the Mars Climate Orbiter in 1999.  My teacher told us that because of this, they started using metric in science classes.

Me:  Well, she was mistaken. We were taught the metric system and they also taught us Roman numerals.

Katie:  They spent maybe 10 minutes teaching us about Roman numerals and my band director went off on that when we did not know when a piece of music was written, because we could not decipher the date.
