> It can be summer and 90degrees in Turin, and inside the cathedral is 30 degrees and so chill.

Which temperature scale are you using here?

[throw_pm23]

I suppose Celsius and 90 is a poetic exaggeration for 35+, while 30 being realistic for inside a stone-building mid-summer in Italy.

Alternatively, Fahrenheit, and 90 is realistic for outdoors mid-summer in Italy and 30 is a poetic exaggeration for ~80 inside a stone-building. If meant literally, the holy water would freeze inside the cathedral. Besides, nobody uses Fahrenheit in Europe, but poetic exaggeration is common.

I've never heard of anyone proclaim 30 deg c as being "so chill". Also much hotter than what I would expect a cathedral to be.

But then again, I am sensitive to heat.

Probably not Kelvin.

Shitty life-hacks: you can ballpark converting from Celsius to Fahrenheit by multiplying by 2!

[throw_pm23]

This life-hack is significantly improved if you change it to:

C->F: multiply by 2, then add 30

F->C: subtract 30, then divide by 2.

At room temperatures, the +32 is significant, at cooking temperatures, who's oven is even accurate to 16/32 degrees? It depends on if knowing the "right" answer is more important than knowing an answer that will get you to what you want e.g., tasty muffins rather than charcoal briquettes :)

Ill say. If I follow GPs life-hack for 30C I get 60F, which is significantly different from 86F. Some life-hack.

[combray]

30*2 + 30 = 90, which is pretty close to 86.

Going the other way

86-30 / 2 = 28 which is close to 30.

I was referring to the comment above that one.

That's why they called it a "shitty" life hack.

[elviejo]

This is the correct life hack. is approximate enough to give you an idea. and easy enough to do mentally
