What are the pros and cons of using Fahrenheit?

Answer 1

Pros:

• Fahrenheit may be familiar to the population of the country that uses it and change is always difficult;
• Fahrenheit has smaller degrees than Celsius so there is less need to use decimals;
• ...

Cons:

• Celsius is used in science so all Fahrenheit temperatures have to be converted to Celsius when teaching or using science
• Kelvin which is the absolute temperature scale has the same unit intervals as Celsius but Fahrenheit has to be converted using the not easy to remember formula: K = (F - 32) x5/9 + 273.15
• Fahrenheit is slightly less "intuitive" when it comes to the boiling point of water 212 oF compared to 100 oC and freezing point of water 32 oF or 0 oC
• ...

Points of Interest:

• Fahrenheit uses a mixture of brine+ammonia to obtain zero and body temperature as 100
• Celsius uses the melting point of water as zero and 100 as the boiling point of water to get its degree intervals
• Kelvin is an absolute temperature scale with zero corresponding to the theoretical point of no energy. 0 K = -273.15 oC. (Note Kelvin does not use the degree symbol)

Answer 2

Pros: Fahrenheit scale is more precise for everyday temperature measurements, with smaller degree increments than Celsius. It is commonly used in the United States and some other countries, making it easier for individuals in those regions to relate to temperature readings. Cons: Fahrenheit can be more difficult to convert to Celsius, which is the standard unit of temperature measurement in most of the world. This can cause confusion when communicating temperatures internationally.
