It is the temperature that has ABSOLUTELY no motion. It is called absolute zero. The Kelvin scale was introduced to be focused around the absolute zero temperature. When you convert Celsius to Kelvin you just add 273 to the Celsius scale. If you do that to your degrees right here... your Kelvin scale would read 0. The lowest degree possible for Celsius is -273 for Kelvin it is 0.

Start by taking the number in Celsius and multiply it by 9. Then divide that number by 5, and then add 32. This is how you convert Celsius to Fahrenheit or use the equation F = (9/5)C + 32
In this case, the answer is also -40 degrees Fahrenheit.

Nothing special. That's a very cold temperature though, at least for humans and most living beings. -40°C is the temperature at which the Celsius and the Fahrenheit scale happen to have the same numerical reading, i.e., when it is -40°C, it is also -40°F.
