°C = (°F − 32) × 5/9
The two scales intersect at −40° — that is the one temperature where Celsius and Fahrenheit are equal.

Quick Mental Math
For a rough estimate going from Celsius to Fahrenheit: double the Celsius value and add 30. For example, 25°C ≈ (25×2) + 30 = 80°F (actual: 77°F). Close enough for everyday use, though use the converter above for precision.
