418 METEIC SYSTEM OF WEIGHTS AND MEASUEES. 



The temperatures given in this book are expressed 

 throughout in degrees of the Centigrade thermometer, un- 

 less otherwise specified. The following is a short compara- 

 tive table of the two scales, Centigrade and Fahrenheit. 



The formula for converting degrees on Fahrenheit's 

 scale to corresponding degrees on the Centigrade scale is 

 (F. 32) = C.; and for converting Centigrade to Fah- 

 renheit, | C. +32 = F.. For further data with regard to 

 thermometer scales, see Part L
