This equation states the relationship between temperature in Celsius (C) and temperature in Fahrenheit (F):


F = 9
5
 C + 32


Many of us know that water freezes at 0°C.
Using the equation, we can work out that this is equal to 32°F.

We also know that water boils at 100°C, which is equal to 212°F.

Is there a temperature at which Celsius and Fahrenheit readings are the same?

Is there a temperature at which the Fahrenheit reading is 20 degrees higher than the Celsius reading?

Is there a temperature at which the Celsius reading is 20 degrees higher than the Fahrenheit reading?
