36. System for Measurement Unit Configuration
There is a device that measures the following parameters. It provides readings in the preferred unit system as follows
- Temperature: Celsius, Fahrenheit
- Distance: Kilometers, Miles
- Weight: Kilograms, Pounds
- Volume: Liters, Gallons
Where users can select their preferred unit e.g. Temperature- Celsius, Distance- Miles, etc.
Create a system to change unit preferences and save the preferences such that they will be retained even if the device restarts/ powered OFF.
Also, the user will have the option to restore it to the default factory setting.

3. It must accept the changes from the user and update the EEPROM.
