72 degrees Fahrenheit is equal to approximately 22.2 degrees Celsius. To convert Fahrenheit to Celsius, you can use the following formula:

$$Temperature\ in\ Celsius\ (°C) = (Temperature\ in\ Fahrenheit\ (°F) - 32) \times \frac{5}{9}$$

Using this formula, we can calculate that:

$$72°F = (72 - 32) \times \frac{5}{9} = 40 \times \frac{5}{9} = 22.2°C$$

Therefore, 72 degrees Fahrenheit is approximately equal to 22.2 degrees Celsius.
