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
15; 32-17=15
-15 degrees celsius
(-15) degrees Celsius = 258.15K
-15 degrees Celsius = 5 degrees Fahrenheit
-15 degree Celsius is colder than -3 degrees Celsius.
15 degrees C
-15 degrees Fahrenheit = -26.1 degrees Celsius
15 degrees Celsius = 288.15 kelvin
15 degrees Celsius = 59 degrees Fahrenheit.
-15 degrees Celsius = 5 degrees Fahrenheit
(-15) degrees Celsius = 5 degrees Fahrenheit.
15 degrees Celsius = 59 degrees Fahrenheit
