There is a number of different systems of measurement in practical use. Most of the world has adapted a decimal system called metric. Its main advantage is all multiples and submultiples of the base units are related to the base unit by factors of powers of ten. Technically, there are various metric systems. Currently International System of Units (SI) which is based on meter, kilogram and second is recognized as the standard one. In US the imperial and customary units are still utilized in trade and household use.
