Why is Celsius more used than Fahrenheit?

Answer 1

The unit Celsius is part of the SI metric system of which countries such as China, and countries that compose of Europe primarily use. The United States is the only country that uses unit Fahrenheit when referring to temperature. However, using Celsius to display the temperature of the weather or anything in particular seems much more practical because it's easier to refer to and remember. In Celsius, the freezing point of water is 0 degrees, but in Fahrenheit, it's 32 degrees.

Answer 2

Because it is an internationally accepted standard rather than one used by a few recalcitrant countries. The zero of the Celsius scale is the freezing point of water rather than the contrived zero of the Fahrenheit scale (the lowest temperature of liquid brine). The upper point of the main scale, 100 degrees C, is where water boils rather than some arbitrary number such as 212 deg F.

Also, the Celsius scale is conveniently related to other physical measures: for example, a [gram] calorie is the amount of heat energy required to raise the temperature of 1 gram of water by 1 degree C. Finally, the Celsius scale uses the same degree as the absolute Kelvin scale, where 0 is a non-arbitrary temperature - one where thermodynamic energy would also be zero.

The only redeeming feature of the Fahrenheit scale is that, because its units are smaller, whole number temperatures are more useful for weather reports.

Answer 3

Celsius is more commonly used worldwide because it is based on the freezing and boiling points of water, making it more intuitive for everyday temperature references. Additionally, the Celsius scale is part of the International System of Units (SI), which promotes consistency and standardization in scientific measurements.
