40 degrees Celsius or 104 degrees Farenheit?

No doubt we will see a mixture in the papers. It's more than 100 degrees Farenheit but 104 doesn't sound as meaningful as 40 degrees Celsius.

Personally - 40 C makes sense to me. I don't know what 100 F is - although I could work it out. I am not sure what a comfortable room temperature is in F but I know that I like 18 C - 20 C

So will you be saying it's 40 C or 104 F?

Exactly. Which is why my parents, in their 70s, would be embarrassed to use farenheit or any imperial measurement. The correlation between using outdated measuring systems and reading the Daily Mail and voting for Brexit is strong. These are all things they find repellant and are affronted when anyone assumes any of them about them just because of their age.

A rough conversion from Centigrade to
Fahrenheit is double it and add 30, so 12° centigrade is 12 +12=24 + 30 = 54° Fahrenheit.

As you get further up the scale in degrees C, it becomes less accurate by a few degrees, so 40° C is 40+40=80+30=110, when we know that it is actually 104°F.

9/5C + 32 = F

F - 32 / 9 x 5 = C

One of the very few things I learned in maths at school which has stayed with me!

I'm 55, I tend to use Celsius and decimal measurements but I understand Fahrenheit and imperial too, mainly due to a partial UK and partial US education, lol

I used metric/SI at school and Imperial at home (49).

It's not hard to switch between the two depending upon who you're speaking to on the basis of age/age+nationality. It's the nearest a lot of us (those who didn't have compulsory foreign language qualifications at school) have to understanding a second language.
