The standard for measuring temperature is referred to as the temperature scale. It is the starting point (zero point) of the reading to determine the temperature and the basic unit (degrees) of the measured temperature.
First, commonly used "temperature standard"
1. Fahrenheit temperature scale (° F ) : The Fahrenheit temperature scale stipulates that the water has a freezing point of 32 degrees and a boiling point of 212 degrees at one atmosphere. The zero point and the boiling point are equally divided into 180 equal parts. Each aliquot represents a degree of Fahrenheit and is expressed in ° F.
2. Celsius temperature scale (°C): The Celsius temperature scale is divided into 100 equal parts between the freezing point and the boiling point. Each aliquot is called a degree Celsius. Expressed in °C. The freezing point is specified to be zero degrees (
3. The conversion relationship between Celsius temperature (°C) and Fahrenheit temperature (° F ) is:

C = ——(F - 32)

Second, the international practical temperature scale
In addition to Celsius temperature, there is also a Kelvin temperature scale. The Kjeldahl temperature scale stipulates that the temperature at which the molecular operation stops is absolute zero. Its symbol is represented by " T " and its unit is Kelvin. The unit symbol is indicated by K. The conversion relationship between the Kjelda temperature scale and the Celsius temperature scale is:
t=TT 0
