help me as i am not good in math. also if you know how to convert miles to kilometers etc etc..well i think there must be a cheat sheet or an easy formula to learn that you can do in your head.

I could give you the mathematical formula, but I don't get the impression that is what you are wanting. Assuming you are talking about outside temperatures and not scientific temps (such as heat of combustion, chemical reactions, etc.) then you only need to remember a few temps:
-40F = -40C (F and C get pretty close when you get down "below zero")
32F = 0C, water's freezing point
75F ~ 23C, a nice comfortable day
high 90s F ~ 30C, a really hot day
212F = 100C, water's boiling point
For miles to kilometers, multiply by 1.6 which is about half again as much. For km to miles, multiply by .6, which is pretty close to half.
A 10k run is about 6 miles. 60mph is about 90km/h.
None of these are exact, but they are all in the ball park.

C = 5/9(F-32)
F = 9/5C +32
If you did not care about being exactly right, and only wanted a ballpark figure, you could use:
C = 1/2(F-32)
F = 2C +32
A kilometer is approximately = 5/8 mile

to change c to f use 9c/5+32
to change f to c use 5/9(f-32)
Example 1: convert 95 degrees ferenheit to degrees celcius
5/9(95-32)
5/9 x 63
35 celcius
Example 2 : convert 55 degrees celcius to degrees ferenheit
9(55)/5+35
495/5=99
99+32=131 ferenheit
go to this site its a conversion calculator http://www.nettam.com/convert.htm

celsius= 5/9(F-32) Fahrenheit=9C/5 +32

ºF = (9/5)ºC + 32
