It's a lousy rainy day today. And my cisco book got all wet.

Give me snow any time now! Much dryer.

Not much rain or snow or cold on Phoenix - lots of hot air, though.

Winter is coming here, was quite cold this morning, well compared to regular sumer weather. Must of been about -1 or so. Right now it's 7.

oh please!!

Conversion of Temperature
There are two main temperature scales. The Fahrenheit Scale (used in the US) , and the Celsius Scale (part of the Metric System, used in most other Countries)

They both measure the same thing (temperature!), just using different numbers.

If you freeze water, it measures 0o in Celsius, but 32o in Fahrenheit
If you boil water, it measures 100o in Celsius, but 212o in Fahrenheit

The difference between freezing and boiling is (0 to 100 =) 100o in Celsius, but (32 to 212 =) 180o in Fahrenheit.

Looking at the diagram, notice:

The scales start at a different number (32 vs 0), so that will need to add or subtract 32
The scales rise at a different rate (180 vs 100), so we will also need to multiply
And this is how it works out:

To convert from Celsius to Fahrenheit, first multiply by 180/100, then add 32.
To convert from Fahrenheit to Celsius, first subtract 32, then multiply by 100/180

Note: 180/100 can be simplified to 9/5, and likewise 100/180=5/9.

Example 1
Convert 26o Celsius (A nice warm day!) to Fahrenheit

26× 9/5 = 234/5 = 46.8
46.8 + 32 = 78.8o F

Example 2
Convert 98.4o Fahrenheit (Normal Body Temperature!) to Celsius

98.4 - 32 = 66.4
66.4 × 5/9 = 331/9 = 36.9o C

If I don't specify the unit, assume it's celcius (the real scale

) Actually sometimes the numbers match up on both scales. (-40)
