Woohoo!

Thanks, Q.

 

Wait, wait, wait - I posted those beautiful conversion formulas just for you, little guildenstern, and you didn't use them!? I feel so unloved :(

Well the truth is (*ashamed*) they looked a little froody to me and I thought you were just being facesious... it was the whole (9/5) / (5/9) thing that threw me! I didn't see those fractions as having any place in those formulas! And I still don't!! I'm sorry O_O

Except now I see that that probably means "divided by" and so I feel even more dork-assier. Ah well.

me not smrt to nokw the convershuns.

 

But now I know for next time.

*SNIFF* Well, okay...

 

But they are for real. It does make sense because there should be a scaling factor (the fraction) and an offset (the 32).

 

Try it with what you know - boiling and freezing. Boiling point in F is 212 and in C is 100.

 

Remember the formulas:

 

To convert Celcius to Fahrenheit: F = C * (9/5) + 32

 

To convert Fahrenheit to Celcius: C = (F - 32) * (5/9)

 

So, let's do boiling, C to F.

F=100*(9/5)+32 = 100*1.8+32 = 180+32 = 212

OK, it works.

 

Now backwards just for good measure.

C=(212-32)*(5/9) = 180*(5/9) = 180/1.8 = 100

OK, that works too.

 

For freezing (32 F and 0 C), C to F.

F = 0*(9/5)+32 = 0+32 = 32

OK.

 

For F to C

C = (32-32)*(5/9) = 0*(5/9) = 0

OK.

 

So, there's some intuition that it works from checking those examples.

 

Now for your specific tempuratre, 27 C.

F = 27*(9/5)+32 = 27*1.8+32 = 48.6+32 = 80.6

So, that's what it is.

 

See, I wouldn't lie to you! Now keep those formulas handy!

Hmm, actually...

 

I had been thinking about doing a thread about how some various parts of a computer work, for those interested but who have not have the opportunity to learn yet. Maybe something like that.
