(From Gould's Dictionary of Medicine) 



To change Centigrade to Fahrenheit : (C X |) -i- 32 = F. 



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

 + 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° — 83°) 

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



■whence — 72° X 



• 40° C.
