Use the Settings 
panel to change the units of measurement you’d like to use in your model. You can also choose how many decimal places to display.
Notes:
- Anyone with access to a shared model can update the settings. Once modified, the units are updated for everyone.
- When you change the settings, they are not only applied to measurement, but they’re applied to the distance used for the Show Nearby and Show Only Nearby commands.
Currently, you can only modify settings in a desktop environment.
