What is the weather forecast of my Apple mobile phone over 80 degrees?

Fahrenheit temperature. It's normal to convert it into degrees Celsius.

Centigrade is a unit of temperature measurement with the symbol "℃", which is widely used in the world at present. It was first proposed by Swedish astronomer anders celsius in 1742, and has been continuously improved since then.

The meaning of Celsius degree means that the temperature of pure ice-water mixture is 0 degree and the boiling point of water is 1 00 degree at 1 standard atmospheric pressure, and the period is divided into 100 parts on average, and each part is 1 degree, which is recorded as1degree. Celsius temperature has been incorporated into the International System of Units (SI). T(K)=t(℃)+273. 15, where t is the absolute temperature.
