THE METRIC SYSTEM 

 UNITS THE MOST COMMONLY USED DIVISIONS AND MULTIPLES 



Centimeter (cm.), o.oi Meter; Millimeter (mm.), o.ooi 

 Meter; Micron (/*), o.ooi Millimeter; the Micron is 

 the unit in Micrometry. 



Kilometer, 1000 Meters; used in measuring roads and 

 other long distances. 



THE GR\M FOR f Alilli g ram ( m g-), - O1 Gram. 



W _ T ; Kilogram, 1000 Grams, used for ordinary masses, like 



\\ I- 1 GUT 



I groceries, etc. 

 THE LITER FOR f Cubic Centimeter (cc.), o.ooi Liter. This is more com- 



CAPACITY j mon than the correct form, Milliliter.

Multiples are designated by the Greek prefixes; deka, 10 times; hecto, 100 

 times; kilo, 1000 times; myria, 10,000 times; mega, one million (1,000,000)
