K to C temperatures
#
# Define a function kelvin_to_celsius
# Given a temperature k in Kelvins, returns
# a temperature in degree celsisu units.

# 0 Kelvin is equivalent to -273.15 degrees Celsius.
# To convert from kelvin to celsius, subtract 273.15 from celsiustemperature.

# Run the code to test your function.

##my_kelvin = 273.15 # (water freezes at thistemperature).
##my_celsius = kelvin_to_celsius(my_kelvin)
##print(my_kelvin, "K equals", my_c_temp, "degrees C")
###
### Should say
### 273.15 K equals 0.0 degrees C
##
##another_K = 293.15 # Kelvins
##another_C = kelvin_to_celsius(another_K)
##print(another_K, "K equals", another_C, "degrees C")
### Should say
### 293.15 K equals 20.0 degrees C
