How to convert Celsius temperatures to Fahrenheit:
Multiply the Celsius temperature by 9/5.
Add 32o to adjust for the offset in the Fahrenheit scale.
Example: convert 37o C to Fahrenheit.
37 * 9/5 = 333/5 = 66.6
66.6 + 32 = 98.6o F

How to convert Celsius temperatures to Fahrenheit with mental math.
Double the Celsius temperature (multiply by 2).
Take 1/10 of this number (2 * 1/10 = 0.2) and subtract it from the number above.
Add 32o to adjust for the offset in the Fahrenheit scale.

Example: convert 37o C to Fahrenheit.
37 * 2 = 74
74 * 1/10 = 7.4
74 - 7.4 = 66.6
66.6 + 32 = 98.6o F

How would that work with 0o C?

[Clanad]

Same way...

0o Celsius X 2 = 0

0 x 1/10 = 0

0 + 32 = 32o F

32o F = 0o C.

Try it with -40 degrees Celcius.
