This example problem illustrates the method to convert temperatures from Celsius to Fahrenheit.

Problem:

What is the temperature in Celsius of 77 °F?

Solution:

The conversion formula for °F to °C is
TC = 5/9(TF - 32)
TC = 5/9(77 - 32)
TC = 5/9(45)
TC = 25 °C

Answer:

The temperature in Fahrenheit of 77 °F is 25 °C.
