One of the salient features of the metric system is its coherency, as the units used in measurement are directly related to one another, and a standard set of prefixes based on powers of ten. It also has a standard set of inter-related base units which can be used for deriving smaller of larger units of measure. The metric system is based on the decimal system and avoids fractional notation for its conversions as well as measurements.
