Add 40 to the number. Multiply the sum by 9/5. Subtract the 40.
To convert Fahrenheit to Celsius, do the same thing, except multiply by 5/9.
Another way is to memorize some Celsius temperatures every 5deg. 0C = 32F, 20C = 68F, 25C = 77F, and 100C = 212 F. Then, every time you want to convert an odd Celsius temperature, just remember that every time you go up or down by 1degC, you go up or down by 1.8degF. You'll learn to do it in your head.

multiply by two and add thirtytwo
for example:
25 C x 2 = 50 + 32 = 82 F
that works up to relatively high temperatures, but once you get into the thousands, you should multiply the celcius temperature by 9 and then divide by 5, that will give you the exact temperature.
for example:
5000 C x 9 = 45000/5 = 9000 F

Wellllll... 32 degrees farenheit is equal to zero degrees celsius, right?
Just add 32 degrees when converting... ?? Multiply C x 2 + 32

to convert celsius to farenheit use this equation
F= (1.8)(C) + 32
C= (F-32)/1.8
