Why did the weather forecast of Apple 6plus change to 75 degrees?

The weather forecast of Apple 6plus is changed to 75 degrees to show Fahrenheit, so it can be changed to the commonly used Celsius.

The steps are as follows:

1, open the weather app.

2. The current temperature is Fahrenheit. Click the lower right button, as shown in the figure.

3. There is a degree switch in the lower left corner, which selects the unit of Celsius.

4. It can display our usual degree of Celsius.

Conversion formula:

Celsius temperature, freezing point temperature is 0 degrees Celsius, boiling point is 100 degrees Celsius.

Fahrenheit set the freezing point at 32 degrees Fahrenheit and the boiling point at 2 12 degrees Fahrenheit.

So 1 degree Celsius (1 equal part) is equal to 9/5 degrees Fahrenheit. Then, according to the freezing point temperature, we can get

The conversion formula between Celsius and Fahrenheit is:1℃ = 9×1/5+32 ℉ = 33.8 ℉.

℃ = 5×(℉- 32)/9,℉ = 9×℃ /5+32

Where is the ℉? Fahrenheit,℃? degree Celsius

The conversion formula between Kelvin temperature and Fahrenheit temperature is:

K = ℃+273. 15，K = 5×(℉- 32)/9+273. 15，℉ = 9×(K-273. 15)/5+32

So absolute zero 0 (k) = 9× (0-273.15)/5+32 (℉) =-459.67 (℉).
