Temperature Units Conversion
If the temperature is given as C in degrees celsius, the temperature can be expressed in degrees Fahrenheit with the formula:
[tex]F=\frac{9}{5}C+32[/tex]We are given the temperature as C=-6 °C, thus:
[tex]F=\frac{9}{5}(-6)+32=-10.8+32=21.2^oF\text{ }[/tex]Answer: A. 21.2°F
