What is the formula to convert Fahrenheit to Celsius?

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

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

Subtract 30 from the Fahrenheit temperature and divide the result by 2. For example, 80°F - 30 = 50 / 2 = 25°C (exact is 26.67°C).

What is normal human body temperature in Celsius?
