yeah this is referring to how high it is above normal, not actually 25 degrees celsius. there was a delta of 45 deg Fahrenheit.

Kinda...but you want 77 - 32 (which is 45).

That's not how converting relative Celsius to Fahrenheit works. If I say "it's 10 degrees Celsius colder today than yesterday", that's the same as saying "it's 18 degress Fahrenheit today".

Oops oops yes, mea culpa. Note to self: avoid (posting to) HN after a few drinks. Thanks to all those who corrected me.

REDACTED: No.. not oops. He's wrong, you're right.

Ah why did you reply to your own comment instead of pressing edit. I thought you were the grandparent poster replying to the correction. God damnit.

The "+32" in the conversion from Celsius measures to Fahrenheit measures is to account for the base offset differences in the absolute measures.

It's a temperature difference, not an absolute temperature

25deltaC = 45deltaF (just multiply by 1.8 for delta C to F)
