To convert Fahrenheit to Celsius, you can use the formula:
\[ C = \frac{5}{9}(F - 32) \]
Where \( F \) is the temperature in Fahrenheit and \( C \) is the temperature in Celsius.
In this case, you want to convert 149°F to Celsius:
\[ C = \frac{5}{9}(149 - 32) \] \[ C = \frac{5}{9}(117) \] \[ C = \frac{585}{9} \] \[ C \approx 65°C \]
So, the equivalent temperature in Celsius is 65°C.
