Change the Unit System

You can change the unit system using the Unit System Selector or the Preferences.

When you enter a number in a field, the appropriate unit is automatically appended. If you enter a unit after a number, the number is converted to the current unit. For example, entering 10 in inside a field where millimeters are the current units results in 254 mm being displayed.

Units are displayed with mixed capitalization for readability, but you can use any combination of upper- and lowercase letters when you enter them.
