This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.
This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?
Just post some stuff and don't spam.

I prefer the converted fractions for ease. Your solution while right will confuse most Americans. (1.8x-40c)+32=-40f
Dear fellow Americans: Fun tip, lazy (but inaccurate) math is (2x-40c)+30= -50f which when you get to normal ranges works well enough in a margin of error. Or just learn to enjoy the beautiful thing that is Celsius and stop using/converting to Fahrenheit.
Americans use fractions daily. The rest of the avoids them. The dimensional analysis maybe.
I've done 9/5+32 in my head so much it's easier and faster for me. Then it's 100% accurate to boot.
