Temperature units are typically used in Celsius (Celsius), Fahrenheit (Fahrenheit), and Kelvin (Kelvin).
- Celsius/°C:Swedish astronomer Anders Celsius proposed a temperature scale in 1742, defining the boiling point and melting point of water as 0 and 100.
- Fahrenheit/°F:The temperature scale developed by German physicist Daniel Gabriel Fahrenheit in 1724. It defines the freezing point of water as 32°F and the average body temperature as 98.6°F. The Fahrenheit system is mainly used in the United States, while most other countries use Celsius.
- Kelvin/K:A unit that represents the absolute scale of temperature, developed by British physicist William Thomson, who proposed the Kelvin reference point. Kelvin temperature starts from absolute zero, and when the temperature is 0K, it corresponds to the absolute zero temperature (the molecular thermal motion is completely stopped). The relationship between Celsius and Kelvin is as follows.Kelvin(K) = Celsius(°C) + 273.15
