To convert Fahrenheit to Celsius, you can use the formula:
\[ C = \frac{5}{9} \times (F - 32) \]
Where \( F \) is the temperature in Fahrenheit and \( C \) is the temperature in Celsius.
In this case, \( F = 300 \):
\[ C = \frac{5}{9} \times (300 - 32) \] \[ C = \frac{5}{9} \times (268) \] \[ C = \frac{1340}{9} \] \[ C \approx 148.89 \]
As an integer, the temperature in Celsius is:
\[ C \approx 149 \]
Therefore, 300 °F is approximately 149 °C.
