Fahrenheit to Celsius: (100F -30)/2= 35C

Just remember 100F was Fahrenheit's wife's body temperature when she had a low grade fever. Normal body temperature is 36.8C, and with a low fever it's between 37 and 38C. It's so easy! haha.

Not quite. It is 37.78.

In temperature couple of degrees means a lot.

For outside temperatures it's close enough though. As an American who travels to Central America quite a bit being about to do: (C*2) + 30 to get F is close enough.
