The following formulas convert Celsius to Fahrenheit, and Fahrenheit to Celsius.

Tc = 5/9(Tf-32) and Tf = 9/5Tc+32 where Tc is the temperature in Celsius, and Tf is the temperature in Fahrenheit.

Tc = 5/9 (20-32)

= 5/9 (-12)

= -60/9

= -6.666 degrees Celsius Conversion: 20°F = -6 2/3°C ≈ -6.67°C
