Imperial Rule

Damned Fahrenheit. I don't understand it in the slightest. Everything here only gives the temperature in Fahrenheit and I just don't get it.

This is definitely more confusing than pounds vs kilograms (1 pound is about 500g-ish)
And far more devious than inches vs centimetres (1 inch is about 2 cm-ish)

Knowing the equation doesn't help much:

Celcius       = (Fahrenheit - 32) * (5/9)
Fahrenheit  = Celcius * (9/5) + 32

I'll be buggered if I have to do that in my head every time I want to know the temperature.

So the only other option to just to learn some general temperatures to give me a rough estimate.

This is where the Google weather app on my iGoogle homepage comes into its own. I have a Celsius and Fahrenheit version of the same app side by side as a daily temperature reminder/helper.

Yeah, it's damned cold here still. It was -5C this morning.

So from the above I can calculate that

0C = 32F

5C = 41.5F

10C = 50F

Unfortuntely I haven't needed any temporatures above 50 since i got here. Roll on spring!
