HI. Temperatures Centigrade and Fahrenheit 



Upon the centigrade scale, the freezing-point of water is C. 

 and the boiling-point 100 C. Upon the Fahrenheit scale, the 

 same points are 32 F. and 212 F., respectively. The same in- 

 terval is thus 100 on the one scale and 180 on the other. The 



degree Fahrenheit is therefore - - or - of 1 Centigrade. Any 



loU y 

 temperatures can be converted by using the formulae: 



= ( F< _ 32), 

 y 



32. 



The following table (IV) contains the temperatures from C. 

 to 35 C., with the corresponding values on the Fahrenheit scale 

 (32 F. to 95 F.). 



IV. Vapor Pressures of Water 



Both the Fahrenheit (F) or ordinary and the Centigrade (C) temperatures are given.
