//! The UnitsAPI global functions are used to
//! convert a value from any unit into another unit.
//! Principles
//! Conversion is executed among three unit systems:
//! -   the SI System
//! -   the user's Local System
//! -   the user's Current System.
//! The SI System is the standard international unit
//! system. It is indicated by SI in the synopses of
//! the UnitsAPI functions.
//! The MDTV System corresponds to the SI
//! international standard but the length unit and all
//! its derivatives use millimeters instead of the meters.
//! Both systems are proposed by Open CASCADE;
//! the SI System is the standard option. By
//! selecting one of these two systems, the user
//! defines his Local System through the
//! SetLocalSystem function. The Local System is
//! indicated by LS in the synopses of the UnitsAPI functions.
//! The user's Local System units can be modified in
//! the working environment. The user defines his
//! Current System by modifying its units through
//! the SetCurrentUnit function. The Current
//! System is indicated by Current in the synopses
//! of the UnitsAPI functions.
