THE METRIC SYSTEM.

The fundamental unit of the metric system is the meter (the unit of length). From this the units of ma.s.s (gram) and capacity (liter) are derived. All other units are the decimal sub-divisions or multiples of these. These three units are simply related, so that for all practical purposes the volume of one kilogram of water (one liter) is equal to one cubic decimeter.
