WEIGHTS, MEASURES, AND TEMPERATURES 



As the metric system of weights and m.easures and the Centigrade measurement 

 of temperatures are employed in scientific work, the following tables showing the 

 English equivalents of those in most frequent use are given for the convenience of 

 those not already familiar with these standards. The values given are approximate 

 only, but will answer for all practical purposes.

The next table gives the Fahrenheit equivalent for every tenth degree Centigrade 

 from absolute zero to the boiling point of water. To find the corresponding 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, multi- 

 ply by five, and divide by nine.
