The measurement units used in your PXE user interfaces can be changed according to your own preferences regardless of the permissions you have.
Tip: Preferences can also be changed by administrators for specific users from the Preferences tab of the Manage Users dialog. See Creating a User Profile.
Note: The measurement unit change only applies to the web interface and command line interface. Setting your preferences does not change the default measurement units, which apply to all users before any individual user or the administrator sets preferred measurement units on a per-user basis. See Setting Default Measurement Units for information on changing default measurement units.
