In your head, or with a calculator?
1 degree C is exactly 1.8 degrees F.
With a calculator, 20 C = (1.8 * 20) + 32 = 68 F
To easily do it in your head, notice that the number 1.8 is close to the number 2, so you can round off by multiplying degrees C by 2 (instead of 1.8), and just adding 30 to the result (instead of 32, since you are a few degrees off anyway since 1.8 is not exactly 2). This rule of thumb works well for normal temperatures that you will find in most climates on Earth.
So, in the above example, 20 C => (2 * 20) + 30 = 70 F, which is close enough to the precise answer of 68 F

It's easier to remember the formula if you know the freezing and boiling points of water in both scales.
C = 0deg >100deg ... 100 deg from freezing to boiling
F = 32 deg>212deg ... 180 deg from freezing to boiling
So a deg C is almost twice as big as a deg F, since it takes 180 "Fs" to go the same distance as 100 "Cs"
or, reduced to lowest common denominator = 180/100 = 9/5
Since the same point on the F scale is defined as the number 32 and is equal to the number 0 on the C scale, then 0 in C = 32 in F, you have to add 32 to go from freezing in C to freezing in F.
Therefore the formula is F= (C X 9/5) + 32

The conversion formula is (C Degrees X 9/5) + 32. Celsius Degrees multiplied by 1.8 plus 32 = temperature in Fahrenheit Degrees.

c(9/5)+32 = f
where, c=temprature in celcius
f=temprature in farenheight

The real question is how to convert fathoms into angstroms, isn't it? And other weird stuff. Well, there is an absolutely excellent freeware tool that will convert just about everything. The people that offer the free version would just as soon sell you the fancy one, but the free one will dazzle your teachers and bore your friends. Go to ESB.com and get their unit convertor.

easily? go to this website:
http://www.onlineconversion.com/temperature.htm
its got conversions for just about anything.
otherwise follow these steps:
fisrt, Mulitply the Celsius temperature by 9
next, Divide the answer by 5.
Last, Add 32

Tc = (5/9)*(Tf-32)
Tc = Temperature in celcius
Tf = Temperature in Fahrenheit
from this:
Tf= ((9/5)*C)+32
