The unit system used by default in SCRUFF is determined by the Region setting of your device. To change it, you can change your iOS device's Region setting to one that uses the unit system of your choice or you change these settings only for SCRUFF in the app.
- Go to the device main screen (Home button)
- Open the Settings app
- Tap General
- Tap Language & Region
- Tap Region
- Locate and select a region that uses Imperial units (e.g. United States) or metric units (e.g. United Kingdom)
- If SCRUFF is open, you will need to relaunch SCRUFF using iOS multitasking.
