How do I change my Apple Watch move ring from Kj to Calories (watchOS 6)

On iPhone:

Go to health App.

Then “Show all health data”.

Next click “Active Energy”.

Next scroll to bottom and select “unit”. Change it to the opposite. If it is the one you want you need to toggle to the wrong one and back again anyway.

Go to Apple Watch and click on the activity app and it will (should) update.

I am in iOS 13.2.3 and WatchOS 6.1.

Try this;
