This simulation shows a thermometer. You can use the slider to change the temperature, which you can see in Kelvin, Celsius, and Fahrenheit. Here we have absolute zero at -273 degrees Celsius, which is just slightly off, but no big deal.
You can also see the temperatures of various different things, so you can see those relative to one another.
