Temperature is often measured in degrees Celsius,$^\circ C$, or degrees Fahrenheit,$^\circ F$.
 
The freezing point of water is $0^\circ$C and $32^\circ$F.
The boiling point of water is $100^\circ$C and $212^\circ$F.
 
Is there a temperature at which Celsius and Fahrenheit readings are the same? 

Can you describe a way of converting Fahrenheit readings into Celsius?
Can you describe a way of converting Celsius readings into Fahrenheit?

 
 

An extension challenge:


Scientists often use the Kelvin scale of temperature, where the freezing point of water is $273.15^\circ K$ and the boiling point of water is $373.15^\circ K$. 
 
Is there a temperature at which Kelvin and Fahrenheit readings are the same?
Is there a temperature at which Kelvin and Celsius readings are the same?
