368 APPENDIX 



TEMPERATURE EQUIVALENTS 



The next table gives the Fahrenheit equivalent, in round 

 numbers, for every tenth degree Centigrade from absolute 

 zero to the boiling point of water. To find the correspond- 

 ing F. for any degree C., multiply the given C. temperature 

 by nine, divide by five, and add thirty- two. Conversely, 

 to change F. to C. equivalent, subtract thirty-two, multiply 

 by five, and divide by nine.
