THE METRIC OR DECIMAL SYSTEM

The _metric system_ is a French system of weights and measures much used in the arts and sciences in every civilized country and as each unit is multiplied or divided by 10 to obtain ascending or descending values it is much more convenient to use than the older English system of arbitrary measures.

The metric system is based on the _meter_, which is one-ten millionth of the distance from the Earth’s equator to the North Pole. There are five units, the four latter being derived from the meter and these are:

1. The _meter_ which is the unit of length and is about 3.280 feet in length.

2. The _are_ which is the unit of surface and is 100 square meters in area.

3. The _liter_ which is the unit of capacity and is 1 cubic decimeter, which is equal to 1.0567 United States quarts.

4. The _stere_ which is the unit of solidity and is equal to 1 cubic meter.

5. The _gram_ is the unit of weight and is the weight of 1 cubic centimeter of distilled water at its maxim density.
