You can change the metric display precision – between 3 and 5 digits to the right of the decimal point – from the PCB Editor – General page of the Preferences dialog ( DXP»Preferences). Toggling units at any time does not affect system accuracy as all numerical calculations are carried out at system resolution. The current unit of measurement is reflected next to the dialog's name, as well as in any fields that display a value. Simply click on the icon, in the top-left corner of the dialog, and choose the Toggle Units command from the subsequent menu that appears (shortcut: Ctrl+Q). Many dialogs in the PCB Editor offer the ability to toggle the currently used measurement unit, between Metric (mm) and Imperial (mil).

This dialog provides controls for defining the various grid systems, specifying units of measurement and controlling the display and position of an associated (back) sheet on which the board is placed. Options specific to the active PCB document are defined in the Board Options dialog, which can be accessed by choosing Design✻oard Options from the main menus. The following sections offer useful hints and tips with respect to viewing and inspecting PCB documents in the main design window.
