THEILMOMETKIC SCALES 



On the Fahrenheit scale the freezing-point of Avater is 

 32°, and boiling-point 212°; on the Centigrade scale the 

 freezing-point is at zero, and the boiling-point at 100°. 



The following formula is used for converting Fahrenheit 

 into Centigrade and vice versa : 



F. into C. = (degree - 32) ^ 9 x 5. 

 C. into F. = degree -•- 5 x 9 + 32.
