Multiply by nine, divide by five, and add thirty-two is the formula for what conversion?

brooksy92491, sorry, it doesn't work. 100 x 2 + 30 = 230 and not 212....

new info for me.thanks

The USA and I believe one third world country are the only places where Fahrenheit is still used. The vast majority of countries in the world use the Celsius scale for temperature.

deebea, same thing

Maybe, just use Celsius all the time and forget about Fahrenheit 😅

I double it take 10 percent off and add 32

Wouldn't it be easier to say (C) Celsius x 1.8 + 32 = (F) Fahrenheit. the wording off the question threw me momentarily, yet due to remembering my favourite equation, I got to the right answer & in time aswell

brooksy92491, you'd better go back to school. Using your formula boiling point of water is 230°F

Player #272443, I got it right without even thinking about it!!

veritates loquitur, I got it right without even thinking about it!!

Bit complicated. Just double and add 30. Hey presto! Celsius to Fahrenheit..
