Question

Convert ${40}^{o}C$ to Fahrenheit.

• A. ${104}^{o}F$
• B. ${107}^{o}F$
• C. ${117}^{o}F$
• D. ${124}^{o}F$

Answer 1

The correct option is A ${104}^{o}F$

The conversion of temprature from Celcius to Fahrenheit is

${}^{\circ }F=\frac{9}{5}{\times }^{\circ }C+{32}^{\circ }$

For ${40}^{\circ }C$

${}^{\circ }F=\frac{9}{5}\times {40}^{\circ }+{32}^{\circ }{}^{}{}^{\circ }F={72}^{\circ }+{32}^{\circ }={104}^{\circ }$

So option $A$ is correct.
