Question

Which sentence has correct capitalization? Do they use Fahrenheit thermometers to measure temperature in the swiss alps? Do they use fahrenheit thermometers to measure temperature in the Swiss alps? Do they use Fahrenheit thermometers to measure temperature in the Swiss Alps? Do they use fahrenheit thermometers to measure temperature in the swiss alps?

Answer 1

The third sentance because Swiss Alps is a proper noun, a place, and Fahrenheit is a unit of temperature, also a proper noun.

Answer 2

I think it's the third one since Fahrenheit should be capitalized and Swiss Alps should be capitalized since it is a specific mountain range/landmark.
