# Unit System

IGC allows the user to change the units displayed during various aspects of flight. The unit system can be changed by navigating to <mark style="color:orange;">**Application Settings**</mark>**&#x20;>&#x20;**<mark style="color:orange;">**General**</mark>**&#x20;>&#x20;**<mark style="color:orange;">**Units.**</mark>

{% hint style="warning" %}
NOTE: IGC must be rebooted for changes to the unit system to apply.
