How do you convert Celsius temp to Fahrenheit?

If you have to know how to do it manually:

Tf = ((9/5)*Tc)+32

For example, to convert a Celsius temperature of 100 into degrees Fahrenheit, first multiply the Celsius temperature reading by nine-fifths to get 180. Then add 32 to 180 and get 212°F.

Or if it's not for school and you don't have to show your method, use a website. I have the page in the source bookmarked, it converts temperature, distance, weight, etc, etc. Very useful!

I like to use Google. It can do lots of conversions. For example, go to google.com and enter "20 celsius in fahrenheit" and you get:

20 degrees Celsius = 68 degrees Fahrenheit

Double the celsius temperature and then add 32. This will put you winthin one degree Fahrenheit

(temp Celsius) * 1.8 + 32 = temp Fahrenheit

so if it's 15 degrees C, 15*1.8+32=59 degrees F

100*9 =x

x/5 =z * 32=

100*9/5+32=
