75 degrees Fahrenheit is equal to 23.89 degrees Celsius. To convert Fahrenheit to Celsius, you can use the following formula:

$$T_{(°C)} = (T_{(°F)} - 32) \times \frac{5}{9}$$

Using this formula, we can calculate that:

$$75°F = (75 - 32) \times \frac{5}{9} = 23.89°C$$

Therefore, 75 degrees Fahrenheit is equal to 23.89 degrees Celsius.
