[–] vala@lemmy.dbzer0.com 14 points 11 hours ago (3 children) Wait... -40c == -40f Really? permalink fedilink source hideshow 3 child comments replies: [–] untorquer@quokk.au 18 points 11 hours ago (2 children) 9/5(conversion ratio) of -40 is -72 which is 32(offset) below -40. So... (9/5[F/C])*(-40[C])+32=-40[F] is where they meet. permalink fedilink source parent hideshow 2 child comments replies: [–] Stupidmanager@lemmy.world 2 points 3 hours ago (1 child) 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. permalink fedilink source parent hideshow 1 child comment replies: [–] untorquer@quokk.au 1 point 1 hour ago 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. permalink fedilink source parent
