A rough guide to Celcius
In the past, when talking with someone from the non-US rest of the world and they would give a temperature in degrees Celcius, I would have to quickly do the mental math to convert to degrees Farenheit to get a sense of how warm or cold they were describing.

But in my recent trip to Australia, I finally worked out the the amazingly simple "rough guide to Celcius".

From zero to 10, wear a coat.
From 10 to 20, wear a jacket.
Room temperature is 20.
From 20 to 30, wear a shirt.
From 30 to 40, it's hot.
And 40 and above, find an AC before you heatstroke.

That wasn't hard at all.

or for F,

40 = cold
70 = neutral
100 = hot

More accurately:

0 = freezing point

4 = frost/snow starts melting

16-20 = room temperature

38 = human body temperature

40 = fever

60 = contact with items at this temperature or above may cause scalding/burns

Generally, I use these "facts" to understand temperatures in either F or C:

32F = 0C. Cold. Water freezes.

72F = ~22C. Comfortable room temperature.

98.6F = 37C. Body temperature. Hot.

Re: A rough guide to Celcius

Nice... I'll remember that in Europe this summer.

One suggestion:
From 30-40, go naked.
(yes, I live in San Francisco)

Living in Japan, I have noticed that very same thing. The difficulty comes when you want to cook and you either have a recipe if F and are using a C oven, or vice versa.

Do you know what 350F is in Celcius?

this from a bus driver in Victoria:

20 is hot
15 is nice
10 is cold
0 is ice
