Your company has certain preferences and settings which span across your organization, such as a unit of measure (cm vs. in) or default currency.
Note: If you have multiple users in your organization unless you set their permissions to deny access, they will also be able to view (and change) these settings.
How to edit/update your organizational preferences:
Go to Settings > Account > Preferences. From here you can edit all fields including mileage unit (km vs. mile), measurement unit (cm vs. in), write-off allowance for mileage, default currency, and timezone.
