What are the lower and upper fixing points in Celsius and Fabrcnheit scales?

Explanation

Centigrade(Celsiums) scale of temperature :
In centigrade scale of temperature lower fixed point is freezing point of water aL one atomsphere pressure, as `0^(@)C` .The upper limit is boilling point of water at 1 atm pressure, as `100^(@)C`.
Fahrenheit scale of temperature:
In Fahrenheit scale, the lower fixed point is freezing point of water at one atmosphere pressure , as `32^(@)F`. The upper fixed point is boiling point of water at 1 atm pressure, as `212^(@)F`.
