3 degrees Fahrenheit equal how many degrees Celsius?

Answer 1

3° F = -16.11° C

The way to remember the formula is that 212° F = 100° C, and 32° F = 0° C.

From this you can derive: F=9/5C+32

The separation between degrees Celsius is wider than the separation of Fahrenheit degrees. There are 5/9 change in degrees Celsius for every degree change of Fahrenheit. So a 3° change Fahrenheit is 15/9 or 5/3 (1-2/3) degree change in Celsius.
