Metric Weights and Measures 



Metric weight 



One gram is the weight of one cubic centimeter of distilled water 

 at its maximum density (39.1 F.) in a vacuum. As a matter of 

 fact, however, the gram now in use is the one-thousandth part of the 

 weight of a kilogram of platinum, which was deposited in the Palace 

 of the Archives in Paris, in 1799, by the international commission 

 which was appointed to fix the standards of what is now known as the 

 metric system.
