What is the formula to convert Celsius to Fahrenheit?

The formula to convert Celsius to Fahrenheit is: Fahrenheit = (Celsius * 9/5) + 32.

What is the quick way to estimate C to F in my head?

For a quick estimate, double the Celsius temperature and add 30. For example, 20°C * 2 = 40 + 30 = 70°F (exact is 68°F).

At what temperature are Celsius and Fahrenheit equal?

Celsius and Fahrenheit are equal at -40 degrees (i.e., -40°C = -40°F).
