 COMPARISON OF THERMOMETERS. 



(From GQiild's Dictionary of Medicine) 



To change Centigrade to Fahrenheit: (C X f ) + 32 = F. 



For example, to find the equivalent of 10 Centigrade, C = 10 (10 X f) 

 + 32 = 50 F. 



To change Fahrenheit to Centigrade: (F. 32) X f = C. 



For example, to reduce 50 F. to Centigrade, F. = 50 and (50 32) 

 X f = 10 C. or 40 F. to Centigrade, F. = 40 ( 40 32) = 72, 

 whence 72 X f = 40 C.
