Example of how it might work:

x = Temperature(20, "c") #Room temperature
print x
y = x.converto("f")      #Room temperature in Farenheit
print y
print y == x
print Temperature(30, "c") + y #Addition of measurements with different units


Output:

20 (c)
xx (f)   #heh, don't know the exact conversion
50 (c)  #First measurement in an operation would be used for the return value
