Check the fuses. If they are good, the electroluminescent display has failed. The flourecence may have been affected by temperature change or age.
To switch the temperature unit on your multi function display from Fahrenheit to Celsius, consult your vehicle's user manual for specific instructions. Typically, you would navigate through the settings menu on the display panel using the buttons or touchscreen to find the temperature unit setting and select Celsius.
Press and hold the recirculation button. Then press the temperature up ("+") button to switch between degrees Celsius & Fahrenheit on the Climate Control Temperature and Instrument Panel Outside Temperature displays.

Look for an option related to display preferences, then select the temperature display setting. Follow the on-screen prompts to switch from the direction indicator to the temperature display.
The change is 7 Celsius degrees (NOT degrees Celsius).
To convert from Kelvin to Celsius, simply subtract 273.15 from the temperature in Kelvin. So if the temperature changes by K in Kelvin, it will also change by K in Celsius.
You can find the change in temperature by subtracting the initial temperature from the final temperature. For example, if the initial temperature is 20 degrees Celsius and the final temperature is 30 degrees Celsius, the change in temperature would be 10 degrees Celsius (30 - 20 = 10).
The temperature change of 1 degree Celsius is equivalent to approximately 1.8 degrees Fahrenheit. This means that the temperature would change by 1.8 feet when converted from Celsius to Fahrenheit.
