The metric system is a decimalised system of measurement. It exists in several variations, with different choices of base units, though the choice of base units does not affect its day-to-day use. Over the last two centuries, different variants have been considered the metric system. Since the 1960s the International System of Units (SI) ("Système International d'Unités" in French, hence "SI") has been the internationally recognised standard metric system. Metric units are widely used around the world for personal, commercial and scientific purposes. A standard set of prefixes in multiples of 10 may be used to derive larger and smaller units. However, the prefixes for multiples of 1000 are the most commonly used~
the SI system and Metric system?
The metric system is an international decimalised system of measurement, first adopted by France in 1791, that is the common system of measuring units used by most of the world. It exists in several variations, with different choices of fundamental units, though the choice of base units does not affect its day-to-day use. Over the last two centuries, different variants have been considered the metric system. Since the 1960s the International System of Units ("Système International d'Unités" in French, hence "SI") has been the internationally recognised standard metric system. Metric units are widely used around the world for personal, commercial and scientific purposes. A standard set of prefixes in powers of ten may be used to derive larger and smaller units from the base units.
According to the US CIA World Factbook in 2006, the International System of Units is the official system of measurement for all nations except for Burma, Liberia, and the United StatesHowever, a number of other jurisdictions have laws mandating or permitting other systems of measurement in some or all contexts, such as the United Kingdom — where for example the Traffic Sign Regulations only allow distance signs displaying imperial units (miles or yards) — or Hong Kong. Also, other standardised measuring systems other than metric are still in universal international use, such as nautical miles and knots in international aviation.
Which is better the metric system or the customary system? Why?
Metric system is better .It is the official system of measurement for all nations except for Burma, Liberia, and the United States A standard set of prefixes in powers of ten may be used to derive larger and smaller units from the base units. Originally, units for volume and mass were directly related to each other, with mass defined in terms of a volume of water. Even though that definition is no longer used, the relation is quite close at room temperature and nearly exact at 4 °C. So as a practical matter, one can fill a container with water and weigh it to get the volume. For example,
1000 litres = 1 cubic metre ≈ 1 tonne of water
1 litre = 1 cubic decimetre ≈ 1 kilogram of water
1 millilitre = 1 cubic centimetre ≈ 1 gram of water
1 microlitre = 1 cubic millimetre ≈ 1 milligram of water .---- Countries which have officially adopted the metric system (green). The United States customary system (also called American system or, more rarely, "English units") is the most commonly used system of measurement in the United States. It is similar but not identical to the British Imperial units. The U.S. is the only industrialized nation that does not mainly use the metric system in its commercial and standards activities, although the International System of Units (SI, often referred to as "metric") is universally used in science, and increasingly in medicine, government, and many sectors of industry. The vast majority of U.S. customary units have been defined in terms of the meter and the kilogram since the Mendenhall Order of 1893 (and, in practice, for many years before that date). These definitions were refined in 1959.
The U.S. customary units have common roots with the Imperial units which were used in the British Empire. Many U.S. units are virtually identical to their Imperial counterparts, but the U.S. customary system developed from English units in use before the Imperial system was standardized in 1824, and there are several numerical differences from the Imperial system.

In the United States, metric units are widely used in science and industry, but customary units predominate in household use. At retail stores, the litre is a commonly used unit for volume, especially on bottles of beverages, and milligrams are used to denominate the amounts of medications, rather than grains. Also, other standardized measuring systems other than metric are still in universal international use, such as nautical miles and knots in international aviation.
