Eight degrees below zero Celsius. It is a subtraction problem.
I suggest you convert each of the Fahrenheit temperatures to Celsius (or the other way round, each of the Celsius temperatures to Fahrenheit), and then compare.
15K = -258.15ºCYou can use this equation to convert Kelvin to degrees Celsius: ºC = K - 273.15

15 - x
15 degrees celsius
The difference between 40 degrees Celsius and -25 degrees Celsius is 65 degrees Celsius. This is because you subtract the lower temperature (-25) from the higher temperature (40) to get the difference.

15 degrees Celsius below 0 is -15 degrees Celsius.
15 degrees Fahrenheit = -9.4 degrees Celsius.
-15 degrees Celsius is colder than -3 degrees Celsius. The lower the temperature, the colder it is.
-15 degrees Celsius is equivalent to 5 degrees Fahrenheit.
5 degrees Celsius is colder than 15 degrees Celsius.
(-15) degrees Celsius = 258.15K
15 degrees C
To convert Celsius to Kelvin, simply add 273. So, 15 degrees Celsius is equivalent to 288 Kelvin (15 + 273).
15 degrees Fahrenheit
