The following Python code enables you to convert temperatures, such as Celsius to Fahrenheit and Kelvin, Fahrenheit to Celsius and Kelvin, and Kelvin to Celsius and Fahrenheit.

The program imports the os and time modules so that we can do some tasks such as clearing the screen and using the sleep method. The code can be copied below, or it can be downloaded at the CosmicMatter GitHub repo, by clicking here.

(Note: The most up to date version of the source code will be located on GitHub in the link above. The code below is posted on the day of the posting of this article and not updated frequently).
