Serin serout problem

[skimask]

----------- If I do that I will still have three posibilities with the same conversion won't I?
I mean
1) +C and +F
2) -C and +F
3) -C and -F

And all based from the celsius value....
1) if tempC > 0 then both C and F are positive
2) if tempC => -17 and tempC <=0 then C is negative, F is positive
3) if tempC < -17 then both C and F are negative

or in Kelvin terms...
1) if tempK > 273 then C/F +
2) if tempK => 256 and tempK <=273 then C- and F+
3) if tempK < 256 then C/F -
