The temperature in China is expressed in degrees, so what is the weather forecast temperature in western countries?

The "degree" you say is the abbreviation of "degree Celsius", which is a unit in physics, just like "kilometer, ton", and it is universal all over the world.

But some western countries use Fahrenheit as the unit. One degree Celsius equals 33.8 degrees Fahrenheit.

There is a movie in America called Fahrenheit 9 1 1.

(1) Fahrenheit

17 14 a glass mercury thermometer with mercury as the temperature measuring medium was made in Fahrenheit, Germany. The temperature of the mixture of ammonium chloride and ice water is chosen as the zero degree of thermometer, and the human body temperature is 100 degrees. Mercury thermometer is divided into 100 parts according to the volume expansion distance of mercury from 0 to 100 degrees, and each part is 100 parts. According to the Fahrenheit scale, the freezing point of water is 32 degrees Fahrenheit and the boiling point is 2 12 degrees Fahrenheit.

(2) Centigrade scale

1740 Swedes put forward that the freezing point of water at standard atmospheric pressure is 0 degrees and the boiling point of water is 100 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℃.
