Unit conversion utility
Not sure if this is possible but it would be cool if the forum had an option where you could have some kind of conversion chart or application to convert Celsius and Fahrenheit and inches and centimeters.

Google does this. just type in 5cm to in, 56 fahrenheit to celsius, etc etc and it spits it out for you. I use it a lot.

I have a small program like that for my Palm handheld from www.4bcx.com. Click on "Downloads." It is still available and still free. It is a handy little program.
I regularly teach a class of 14 year olds. It is always fun to convert temperatures from Celsius to Fahrenheit or vice-versa right in front of them in my head with no paper and no calculator. (One degree Celsius is 1.8 degrees Fahrenheit.) Multiply by 2 and then subtract 0.2 times the number from the answer. It is a lot easier to juggle varieties of 2 in one's head than 1.8 and it gets you to the same place. Do not forget to add or subtract 32 for the difference between the systems on the freezing point of water.
For example: calculate 10 deg. Celsius into Fahrenheit .
10 x 2 = 20.
10 x 0.2 = 2.
20 - 2 = 18.
18 + 32 = 50 deg. Fahrenheit.
Calculate 65 deg. F. into Celsius
65 - 32 = 33
33/2 = 16.5
0.2 x 16.5 = 3.3
16.5 + 3.3 =19.8 degrees Celsius

Concerning temperatures, if Fahrenheit is your normal reference and you want to "understand" Celsius temperatures, remember what the Europeans say: "Ten is cool, twenty is comfortable, thirty is hot." That works for a pretty good rule of thumb.
Concerning millimeters to inches, just remember that one inch is about 25 millimeters. So, a 56 cm frame is 560 mm. At 4 inches per 100 mm, 56 cm is about 22 inches.
Usually when I want to convert between English and Metric I am a long distance away from a computer. The little Palm program I mentioned is very portable. But, being able to make a reasonably precise conversion in your head is very helpful.
