II.— LAND MEASURE. 



Metric. 



Hektare, = square of 100 metres, 



dekare, = 10 ares, 



Are, = square of 10 metres, 



New Imperial. 

 = 2J acres. 

 = 1 rood. 

 = 4 square perches. 



III.— WEIGHTS. 



Metric. 



Ton, = 1000 kilos, 



quintogram, or quintal, . . = 100 kilos, 



quartogram, or myriagram, . = 10 kilos, 



Kilo, or kilogram, . . . . = 1000 grammes, 



metric pound, or half -kilogram, = 500 grammes, 



hekto, or hektogram, . . . = 100 grammes, 



dek, or dekagram, . . . . = 10 grammes, 



Gramme, = 



decigram, = ro gramme, 



centigram, = xio gramme, 



Milligram, = ~dW gramme, 



New Avoirdupois.

IV.— MEASURES OF CAPACITY. 



Metric. New Imperial, 



Stere, kilolite, or kilolitre, . = 1000 litres, = 111 J pecks, 



hektolite, or hektolitre, . . = 100 litres, = 11| pecks, 



dekalite, or dekalitre, . . = 10 litres, = 1 J peck, 



metric gallon or half -dekalitre, = 5 litres, = 1 J imperial gallon. 



Litre = = I gallon, or f quart. 



decilitre, = A litre, = it gallon. 



centilitre, = tjjq l itre > = *io gallon. 



Millite, or millilitre, . . . = roVo litre. = 4-500 gallon. 



In measuring commodities for purchase or sale, it shall he lawful to treat the follow- 

 ing measures as equivalent : — 



1 stere, and one cuhic metre ; 



1 hektolitre, and 100 cuhic decimetres ; 



1 dekalitre, and 10 cuhic decimetres ; 



1 litre, and 1 cuhic decimetre ; 



1 decilitre, and 100 cubic centimetres ; 



1 centilitre, and 10 cubic centimetres; 



1 millilitre, and 1 cubic centimetre. 



Note. — The stere differs very little from the cubic metre, the litre differs very little 



from the cubic decimetre, and the millilitre differs very little from the cubic centimetre ; 



the ratio of the stere to the cubic metre, or of the litre to the cubic decimetre, or of the 



millilitre to the cubic centimetre, being approximately the ratio of 100-016 to 100, or 



of 6251 to 6250.
