: Activation of the inch measuring system
The inch measuring system is used to read and write geometric data in units of
length.
Technological data in units of length, e.g. feedrates, tool offsets or settable work
offsets, as well as machine data and system variables, are read and written using
the parameterized basic system (MD10240
$MN_SCALING_SYSTEM_IS_METRIC).
: Activation of the metric measuring system
The metric measuring system is used to read and write geometric data in units of
length.

: Activation of the inch measuring system
All geometrical and technological data in units of length (see above) is read and
written using the inch measuring system.
: Activation of the metric measuring system
All geometrical and technological data in units of length (see above) is read and
written using the metric measuring system.
