The default unit for GCAP is FPS. You can change the unit from FPS to SI and vice versa by following these steps. It is recommended that you change the unit right after starting your new project because if you are still working on a screen, the unit on that screen will not be changed until you close that screen and open it again.
Step 1: Go to the “Preferences” menu and Select “Unit”
Step 2: Select the Unit that you want.
