1. Confirm whether the scale supports unit synchronization with app.
Read the manual to see if the scale supports syncing with APP.
2. If the scale does not support unit synchronization, you need to set the unit on the APP and the scale separately.
3. If the scale supports unit synchronization, you can synchronize the setting information to the scale after setting on the APP. The unit after the scale is synchronized will usually take effect the next time it is powered on for measurement.
