The equation linking Celsius and Fahrenheit is

9*C = 5*(F - 32)


Suppose the temperatures are the same at X degrees.

Then 9*X = 5*(X - 32) = 5*X - 160

4*X = -160

and so X = -40

Centigrade and Fahrenheit same at what degree?

-40


Which is larger a Fahrenheit degree or a Kelvin?

A kelvin is larger. The kelvin "interval" is the same as a centigrade (celsius) degree


Are the freezing water at 32 degrees Fahrenheit the same as 0 degree centigrade?

Yes. we can convert Fahrenheit values to centigrade values and vice versa by the following formula: TC=(TF-32) X 5/9 where TC :Temperature in centigrade TF :Temperature in Fahrenheit


Is the difference in centigrade and Fahrenheit the same?

No.


What is the Fahrenheit equivalent to zero degrees centigrade?

The Fahrenheit equivalent to zero degrees Centigrade is 32. Centigrade is another name for Celsius, and zero Celsius is the same as zero centigrade.


What tempratrure centigrade and Fahrenheit give same reading?

-40


Which temperature has the same value in Centigrade and Fahrenheit?

Negative 40.


What is 9 Celsius?

Celsius is the same as centigrade. So 9 celsius = 9 centigrade = 48.2 fahrenheit.


Which is colder zero Fahrenheit or 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.


What is the significance of -40 degrees Fahrenheit?

When you convert Fahrenheit to centigrade (Celsius) you get exactly the same reading of -40.


When do Celsius and Fahrenheit have same temperature?

-40 Centigrade (celsius) is equal to -40 Fahrenheit.


What temperature is sub zero?

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.
