To convert degrees Fahrenheit to degrees Celsius, you can use the formula:
\[ C = \frac{5}{9} \times (F - 32) \]
Where \( C \) is degrees Celsius and \( F \) is degrees Fahrenheit.
For 63 degrees Fahrenheit:
\[ C = \frac{5}{9} \times (63 - 32) \] \[ C = \frac{5}{9} \times 31 \] \[ C \approx 17.22 \]
So, 63 degrees Fahrenheit is approximately 17.22 degrees Celsius.
