Why are there two different names for the temperature?
The two different names for temperature, Celsius and Fahrenheit, are based on different historical scales developed by different scientists. Celsius, also known as centigrade, is more commonly used internationally and is based on the freezing point (0°C) and boiling point (100°C) of water. Fahrenheit is used primarily in the United States and is based on a scale where water freezes at 32°F and boils at 212°F.
