736 MEASURES OF MASS AND CAPACITY 



The metric system of weights and measures, now legalised 

 in this country, is everywhere extensively used in scientific 

 observations, and, from the simplicity of its decimal grada- 

 tions, is certain to become general. The metric tables of 

 weight, capacity, and length, with their relations to the 

 corresponding English tables, are appended : 



MEASURES OF MASS 



1 milligramme = O'OOl gm. = 0'015432 gr. =approx. / T grain. 

 1 centigramme = O'Ol =0'15432 = ,, ^ 

 1 decigramme = O'l =1*5432 grs. = Ingrains. 

 1 gramme = 1-0 =15-4323 = 15| 



1 decagramme = 10*0 =0*022046 Ib. = 154J 

 1 hectogramme = 100-0 =0-22046 . 



1 kilogramme =1000*0 =2-2046, or 2 Ibs., 3 ozs., and 120 



grains nearly. 



In commerce the kilogramme is calculated as 2 and one- 

 tenth pounds. 



The gramme, taken as the unit of weight, is a cubic centi- 

 metre of water at 4 C. or 39- 2 Fahr. 



MEASURES OF CAPACITY 



1 c.cm., or 1 millilitre = 1 gramme of water = 0-0610 c. in. 



= nearly 17 minims. 

 10 ,, ,,1 centilitre = 10 gramme of water = 0-610 c. in. 



= nearly 170 minims. 

 100 ,,1 decilitre = 100 gramme of water = 6'10 c. in. 



= nearly 3J ounces. 



1000 1 litre =1000 gramme of water =61 '0 c. in. 



= nearly 35J ounces. 



A litre is equal to 1' 75980 pint, or 1 pint, 15 ounces, 

 1 drachm, and 34 minims nearly. 



MEASURES OF LENGTH 



1 millimetre =0'001 metre = 0-039370, or ^ English inch. 



1 centimetre =0-01 = 0-39370, or f English inch. 



1 decimetre =0'1 = 3-9370, or nearly 4 English inches. 



1 metre =1'0 =39-370113, or 1 yard, 3'37 ins. nearly.
