When a parameter uses a small unit, such as centimeters, the parameter should be formatted at the same order of magnitude

E.g. oil level is measured in centimeters, but is being converted to miles in the app UI. We should probably keep units within the order of magnitude that they're defined but converting to the appropriate metric system based on user preferences.

Start at the app UI code that converts parameter units, then trace how user measurement-system preferences are read. Done means small units such as centimeters remain at a comparable order of magnitude while still following the user's metric-system preference; verify the oil-level example in the UI.
