The Benefits of Dual Scale

The main temperature scale of the metric system is the Celsius scale, which is widely used throughout the world. There are only a few countries in the world that use Fahrenheit as their temperature scale, including Belize, the Cayman Islands, the United States, the Bahamas, and Palau.

Since the Celsius scale is the most widely used temperature scale in many countries, people in these countries have the advantage of more easily understanding the readings on the thermometer. If the thermometer had only been measured in F, it would have been less popular in such countries. The dual temperature scale feature makes it more desirable all over the world.
