The correct answer is from Fabio's comment to pedrouan's answer, which references Apple's response on the forums: https://forums.developer.apple.com/thread/70258.

The Simulator does not respect the Temperature Unit setting, but real devices do respect that setting. Using MeasurementFormatter in the Simulator will always use the locale's default unit, but using MeasurementFormatter on a real device will use the user's selected Temperature Unit.
