Why are prefixes used in the metric system?
The metric prefixes can be employed to scale the base units so that they can represent anything from a very large numeric value (for example by using prefixes such as Exa, Tera, or Mega) to a very small numeric value (for example by using prefixes such as Atto, Femto, or Pico).
