How to Convert Between Degrees Fahrenheit and Celsius
By Anne Marie Helmenstine, Ph.D.

Solution:

The conversion formula for °C to °F is
TF = 9/5(TC) + 32
TF = 9/5(20) + 32
TF = 36 + 32
TF = 68 °F

Answer:

The temperature in Fahrenheit of 20 °C is 68 °F.

Celsius and Fahrenheit are the same at -40°, but at ordinary temperatures, the Fahrenheit temperature will be higher than the Celsius value.
