1 Degree Celsius = 1 Degree Kelvin (They just have a different starting point)
Kelvin = Celsius + 273.15
291.15 K = 18C + 273.15
To convert Celsius to Kelvin, simply add 273.15. Therefore, 18 degrees Celsius is equal to 291.15 Kelvin.
To arrange the temperatures from warmest to coldest, you would start with 18 degrees Celsius as the warmest, followed by 4 degrees Celsius, 0 degrees Celsius, -1 degree Celsius, -11 degrees Celsius, and finally, -18 degrees Celsius as the coldest.

The difference between -6 degrees Celsius and 12 degrees Celsius is 18 degrees. This is calculated by subtracting the lower temperature (-6) from the higher temperature (12).

18 degrees Celsius is 291 degrees Kelvin and 64.4 degrees Fahrenheit. Hot and cold are all about personal opinion. The interior of a human is around 37 degrees Celsius, skin is around 34 degrees Celsius. Room temperature is accepted as being 21-4 degrees Celsius but like I said, hot and cold are all about personal opinion, I would class 18 degrees Celsius as 'cool' but I couldn't tell you what hot and cold are for you.
18 degrees Celsius is 64.5 degrees Fahrenheit or 291 kelvin. Not cold.
0 degrees Fahrenheit is approximately -18 degrees Celsius, and 255 Kelvin
-18 degrees Celsius = -0.4 degrees Fahrenheit
18 degrees Celsius = 64.4 degrees Fahrenheit.
18 deg Celsius = 64.4 deg Fahrenheit.
It would have to rise 18 degrees Celsius.
18 degrees Celsius minus 25 degrees Celsius equals -7 degrees Celsius.
20 degrees Celsius is colder than 18 degrees Celsius.
27.6
-7.78 degrees Celsius.
-18 degrees Celsius is equal to 0.4 degrees Fahrenheit.
18 degrees Celsius is already in the Celsius scale. There is no conversion needed as Celsius and centigrade are the same.
