Fun to fuck with people in winter that it will be in the thirties tomorrow. I like to show little kids and see what they say. If they’re younger than ~8, it tends to work, then I get to tell them about the world a little more and if they’re interested, teach them how to convert. That was the first conversion I figured out, it’s pretty easy, and it’s applicable to the real world, so it’s great at getting kids into math.
