## Definition - What does Metric System mean?

The Metric System is the decimal system of measurement which is internationally agreed. Its uncoordinated use by different engineering and scientific disciplines specifically in the 19th century concluded in various choices of the base units, even when all depended on same definitions of the kilogram and the meter. Despite numerous changes and developments in the Metric System since its outset, the basic concepts have not been changed. It has been designed for the transnational use with a basic set of measurement units known as base units.

## Petropedia explains Metric System

The Metric System is the system of measurement units with three commonly used base units – gram, liter and meter. A gram is unit of mass which is approximately equal to 0.0022 pounds, a liter is unit of volume equivalent to 1.05 quarts and meter is unit of length which is equal to 3.28 feet.

The submultiples and multiples of the metric units are related by the powers of ten. The relationship is also compatible with decimal system of the numbers which contributes enormously to the convenience of metric units. The Metric System underwent numerous refinements and scientific progress for base units which resulted into a modern Metric System known as the International System of Units "SI".
