METRIC EQUIVALENTS OF POUNDS, FEET, ETC. 



The government publishes the equivalents in pounds, 

 etc., of the metric system, but the American shipper 

 wants to know what the pounds, inches, feet, and gal- 

 lons, to which he is accustomed, are in the metric 

 system. The following is a convenient table showing 

 the metric values of our measures. Some countries de- 

 mand that the metric system should be used in the 

 consular papers, and in most countries, especially in 

 Latin-America, the consignees ask for the weights, etc., 

 in the metric system. This table will be found valuable 

 for reference by invoice clerks and shipping clerks in the 

 export departments of manufacturing establishments.
