Fahrenheit to Celsius | °F to °C

How the Converter Works:

1. Input:

   • Enter a temperature in Fahrenheit using the input field.

2. Negate Function:

   • The +/− button toggles the sign of the entered value between positive and negative.

3. Calculation:

   • When the “Calculate” button is clicked, the convertTemperature() function is called.
   • The formula for Fahrenheit to Celsius conversion is applied: $$\text{Celsius} = (\text{Fahrenheit} – 32) \times \frac{5}{9}$$
   • The result is displayed in the format: X°F = Y°C, where Y is the temperature in Celsius, rounded to two decimal places.

4. Clear Button:

   • The “Clear” button resets both the input field and the result display.

Examples:

1. Example 1:

   • Input: 100 °F
   • Calculation: $(100 – 32) \times \frac{5}{9} = 37.78 \, \text{°C}$
     
   • Result: 100°F = 37.78°C

2. Example 2:

   • Input: 32 °F
   • Calculation: $(32 – 32) \times \frac{5}{9} = 0 \, \text{°C}$
     
   • Result: 32°F = 0°C

3. Example 3:

   • Input: -40 °F
   • Calculation: $(-40 – 32) \times \frac{5}{9} = -40 \, \text{°C}$
     
   • Result: -40°F = -40°C
