To convert between Celsius and Fahrenheit, use the formula \( °F = \frac{9}{5} (°C) + 32 \).
You can calculate the point where both scales meet by setting them equal to each other.
The relationship between Celsius and Fahrenheit is given by the formula: \[ °F = \frac{9}{5} (°C) + 32 \] For °C = °F, we substitute into the formula: \[ ° = \frac{9}{5} (°) + 32 \] Solving this, we get the answer \( ° = -40 \).
Conclusion:
The temperature at which Celsius is equal to Fahrenheit is -40°.
