Metric System Chart for Kids One of the international standards used for conversion is the metric system. It is a decimal system of measurement, that was first adopted by France in the year 1791. It is common in most parts of the world. There are variations used in different countries, however the difference is in the base units, which does not make a difference in daily usage of these.

There is one point, which distinguishes the metric system from other measurement systems. It is the single unit used to describe every physical quantity. An example will help in better understanding of the system.

The prefixes used in the system are in the powers of ten, that are used for deriving larger, as well as smaller units from the base units. It is important to note that as a normal practice, fractions are not used in the system, because it is more easy and convenient to convert using different multiples in powers of ten rather than using fractions. To avoid decimals, adidas maniaadidas outlet multiples and sub multiples of seconds are used, for example, nano second, mega seconds, etc. There are three basic units, which are a part of the measurement conversion. They are gram, adidas obuv vypredaj meter, and liter. Meter is used for measuring length, while gram is used to measure weight and for capacity, liter is the unit of measurement. These basic units of measure are the only ones where no prefixes are used. Instead of converting them into another unit, prefixes are appended to the measurement. The prefixes used from the highest to the lowest are:Gram / Meter / LiterThe prefix either divides the unit of measure by a power of ten, or multiplies the unit by a positive power of ten.
