Why does the weather forecast on the mobile phone show that the temperature is 76 degrees low and 81 degrees high, which is 30 degrees higher than the appropriate weather temperature?

The mobile phone weather forecast shows a temperature of 76 degrees low and 81 degrees high, which is 30 degrees higher than the appropriate weather temperature because the weather forecast uses Fahrenheit temperatures.

The conversion of Fahrenheit temperature and Celsius temperature is: ℉=(9/5) ℃+32.

The symbol of the Fahrenheit temperature scale is ℉. In 1724, the German Fahrenheit formulated the Fahrenheit temperature scale. He set the temperature when a certain concentration of salt water solidified as 0℉, and set the temperature of pure water as 0℉. The freezing point (ice point) temperature is set at 32℉, and the boiling point (boiling point) temperature of water under standard atmospheric pressure is set at 212℉. The middle is divided into 180 equal parts, each equal part represents 1 degree. This is the Fahrenheit temperature scale, with the symbol F Said, this is the temperature in Fahrenheit.

The regulations of Celsius temperature set the temperature of the ice-water mixture under standard atmospheric pressure as 0 degrees Celsius, and the temperature of boiling water as 100 degrees Celsius. 0 degrees Celsius and 100 degrees Celsius are divided into 100 equal parts, each equal. Minutes represent 1 degree Celsius.
