WEIGHTS, MEASURES, AND TEMPERATURES 



As the metric system of weights and measures and the 

 Centigrade appraisement of temperatures are universally 

 employed in scientific works, the following tables showing 

 the equivalents in our common English standards of those 

 in most frequent use, are given for the convenience of 

 students who have not already familiarized themselves with 

 the subject. The values given are approximate only, but will 

 answer for all practical purposes, except in cases where very 

 great exactitude is required. The micron, or micrometer, 

 is used principally by scientific investigators for measuring 

 extremely minute objects seen under the microscope.
