Here's how to convert between Fahrenheit (°F) and Celsius (°C):

Fahrenheit to Celsius:

* Subtract 32 from the Fahrenheit temperature.

* Multiply the result by 5/9.

Formula: (°F - 32) × 5/9 = °C

Celsius to Fahrenheit:

* Multiply the Celsius temperature by 9/5.

* Add 32 to the result.

Formula: (°C × 9/5) + 32 = °F

Example:

* Convert 77°F to Celsius:

(77 - 32) × 5/9 = 25°C

* Convert 25°C to Fahrenheit:

(25 × 9/5) + 32 = 77°F
