I guess this makes sense although Fahrenheit isn't very scientific.

I use F every day but I don't see the point. I mean other than water (which I know in C.. 0 and 100 lol) these temperatures are just as "random" to me as they would be in F.

ssc4k got the point. however, i would ban all non-SI scales on the planet just because the (most) SI scales are perfectly defined in terms of physical constants and are reproducible

I have programmed something to change temperature scales.

Just powder.c, you can compile it yourself. Run the program with argument 'F'.
