There are only 5 countries in the world that still use Fahrenheit to measure temperature, the Bahamas, Belize, the Cayman Islands, Palau, and the United States.

American’s are stubborn and will often argue that their way is the best no matter what. For example, the Fahrenheit scale is still used for temperature despite it not making total sense as a temperature scale.

Once upon a time Fahrenheit was used by almost all English speaking countries, but in the 1960’s and 70’s most of these countries switched over to Celsius, with the United States being the most noticeable exception.

Today, only five countries, including the United States, use the Fahrenheit scale. The Bahamas, Belize, the Cayman Islands, Palau, and the United States and associated territories (Puerto Rico, Guam and the U.S. Virgin Islands) use the scale for every day applications, though the scientific community around the world uses either Celsius of Kelvin. Canada sometimes uses Fahrenheit, but the official temperature scale is Celsius.

Celsius is now considered the international standard for measuring temperature. It’s likely that one day in the future the remaining Fahrenheit-loyal countries will switch over to this scale. Surely once the United States changes the others would follow suit.
