What is the reason that the weather forecast temperature of mobile phone is 76 degrees lower than the timely weather temperature and 30 degrees 8 1 degree higher?

Mobile phone weather forecast shows that the temperature is 76 degrees lower than the timely weather temperature and 8 1 30 degrees higher, because the weather forecast uses Fahrenheit temperature.

Fahrenheit and Celsius are converted into = (9/5)℃+32.

Fahrenheit scale symbol, 1724, developed by German Warren Hite. He set the temperature of a certain concentration of salt water at 0℉ and the freezing point of pure water at 32 ℉. Let the boiling point temperature of water at standard atmospheric pressure be 2 12℉, and divide it into 180 equal parts, each equal part represents 1 degree. This is the Fahrenheit temperature scale, which is indicated by the symbol F.

The stipulation of the temperature of Celsius sets the temperature of ice-water mixture at standard atmospheric pressure at 0 degrees Celsius, and the temperature of boiling water at 100 degrees Celsius. Temperatures between 0 degrees Celsius and 100 degrees Celsius are divided into 100 equal parts, and each equal part represents 1 degrees Celsius.
