The conversion relationship between the temperature in Celsius (° C) and the temperature in Fahrenheit (° F) is: ° F = 32 + ° C × 1.8, ° C = (° F) -32)1.8.

temperature is a physical quantity that represents the degree of heat and cold of an object. In microcosm, it is a physical quantity used to measure the degree of heat movement of molecules. Temperature can only indirectly, through friends, some characteristics of the object changes with the temperature measurement. The most used temperature scales in the world are Fahrenheit (°F), Celsius (°C), thermodynamic (K), Liehorn (°Ré), Rankine (R) and international practical temperature scale. From the viewpoint of molecular dynamics theory, temperature is a marker of the average kinetic energy of an object’s molecules. Temperature is the collective manifestation of a large number of molecular thermal motions, with statistical significance. But for individual molecules, temperature is meaningless.
03
Fahrenheit (° F) is a measure of temperature, named after its inventor, the German Gabriel D. Fahrenheit (1686-1736). The symbol ℉. Only five countries in the world use degrees Fahrenheit, including the Bahamas, Belize, the British Cayman Islands, Palau, the United States of America and other dependent territories (Puerto Rico, Guam, United States Virgin Islands).
04
The degree Celsius comes from the Swedish astronomer Anders Celsius proposed in 1742, and has been improved since then. The meaning of degrees Celsius means that at 1 standard atmospheric pressure, the temperature of the pure ice-water mixture is 0 degrees Celsius and the boiling point of water is 100 degrees Celsius. It is one of the widely used temperature scales in the world. Celsius is now included in the International System of Units.
