32°F is 0°C which is why you need the 32 in there. For the fraction I always just try to think about whether Celsius or Fahrenheit is bigger. Accordingly, I’ll need a number smaller or larger than one.
edit:
Aight I got the fraction wrong, which kinda proves that it’s useless to remember lmao.
The easy way to remember the multiplier is that there’s exactly 180 degrees between boiling and freezing in Fahrenheit, and 100 in Celsius. Just use 1.8 instead of a fraction.
In Fahrenheit, 0 is the temperature of ice in some random brine, just as 0 in Celsius is the temp of ice water.
Fahrenheit and Celsius are defined nearly identically. Fahrenheit just chose some weird values for its basic constants, like using a weird ice brine instead of just ice water.
Here’s how you convert between the two:
T[°C] = (T[°F] - 32)* 5/9
32°F is 0°C which is why you need the 32 in there. For the fraction I always just try to think about whether Celsius or Fahrenheit is bigger. Accordingly, I’ll need a number smaller or larger than one.

And the -32, hmm? Checkmate, atheists

32 degrees F is freezing, as is 0 C.
Ramen.
I find it easier to do mental arithmetic with the fraction (and I didn’t know the boiling point of water in Fahrenheit). But thanks anyways!
That edit lol I used to know this by heart at some point in my life. Now I’m fine knowing that it exists and use software to do it for me instead
