40=1+3+9+27?? Or how about -40 degree being the unique temperature at which Celsius and Fahrenheit scales correspond? :P

no then 1+2+4+8=15, so it could also be unique, there are n numbers, which follow the above pattern, and there are also other degrees of temp. between 1 and a million like water boils at 100 deg Celsius etc to be unique, so why among 1 to a million 40 can be unique by your statement......But well done for giving knowledge about 40.

Ohh...but -40 degree is the only temperature at which celcius and farenheit become equal ....right?

hey you are right, but it firstly is -40 not 40 k by this logic any one can cross question you why 40 only why not any other number at some other respect...as simplest one there are only 60 seconds in a minute so 60 must be unique among 1 and a million, think about something logically not scientifically ........
