Extended data

Fahrenheit and Celsius are units used to measure temperature. Many countries in the world, including China, use degrees Celsius, while the United States and some other English-speaking countries use degrees Fahrenheit instead of degrees Celsius.

Fahrenheit temperature: choose the temperature of the mixture of ammonium chloride and ice water as the zero degree of the thermometer, and the human body temperature is 100 degrees. According to the volume expansion distance of mercury, the mercury thermometer is divided into 100 parts from 0 degree to 100 degree, and each part is 1 Fahrenheit, which is recorded as "1 Fahrenheit".

Celsius temperature, at standard atmospheric pressure, the temperature of ice-water mixture is defined as 0 degrees, and the boiling temperature of water is defined as 99.974 degrees. According to the two fixed temperature points of water, glass mercury thermometers are graded. Intercropping between two points is divided into 100 equal parts, and each part is called 1 Celsius. Record as 1℃.

The conversion relationship between Fahrenheit and Celsius is: t =1.8t℃+32 (t is the number of Celsius and t is the number of Fahrenheit).
