That's not a zero. The small circle is the symbol for "degree."
The Fahrenheit equivalent to zero degrees Centigrade is 32. Centigrade is another name for Celsius, and zero Celsius is the same as zero centigrade.
Zero degrees Centigrade is the same a 32 degrees Fahrenheit, both mark the freezing point. Therefore 0 degrees Fahrenheit would be much colder than 0 degrees Centigrade.
Zero degrees Celsius is equal to 32 degrees Fahrenheit.
32 F
No, the freezing point of water is 32 degrees Fahrenheit.
Sub-zero is anything that is less than zero. That means that-1 degree, -2 degrees, -3 degrees, etc. are all 'sub-zero'. To be complete, you also have to specify whether you are talking centigrade or Fahrenheit. When centigrade, it just means the same as below freezing (0 degrees centigrade). When Fahrenheit, sub zero is starting to be seriously cold since freezing is +32 degrees Fahrenheit.

Zero (0) degrees, assuming you mean the freezing point of water, which is 32 degrees Fahrenheit.
47 degrees Fahrenheit is 8.33333 centigrade
Most modern domestic freezers are set to -18 Centigrade. (approx zero Fahrenheit)
A Fahrenheit degree is 5/9 the size of a centigrade degree.
Fahrenheit = 5/9 ( Centigrade - 32)
