There are quite a number of temperature scales. For this task we will concentrate on four of the perhaps best-known ones:
Kelvin, Celsius, Fahrenheit, and Rankine.

The Celsius and Kelvin scales have the same magnitude, but different null points.

 0 degrees Celsius corresponds to 273.15 kelvin.
 0 kelvin is absolute zero.
The Fahrenheit and Rankine scales also have the same magnitude, but different null points.

 0 degrees Fahrenheit corresponds to 459.67 degrees Rankine.
 0 degrees Rankine is absolute zero.
The Celsius/Kelvin and Fahrenheit/Rankine scales have a ratio of 5 : 9.



Task
Write code that accepts a value of kelvin, converts it to values of the three other scales, and prints the result.



Example

K  21.00

C  -252.15

F  -421.87

R  37.80
