Editing Metric system (section)

===Ease of learning and use===
The metric system is intended to be easy to use and widely applicable, including units based on the natural world, decimal ratios, prefixes for multiples and sub-multiples, and a structure of base and derived units.

It is a [[coherent system]] with [[derived units]] built from base units using logical rather than empirical relationships and with multiples and submultiples of both units based on decimal factors and identified by a [[metric prefix|common set of prefixes]].<ref name=":0" />{{Rp|pages=15–18}}
