Question

Convert ${122}^{o}F$ into Celsius.

• A. ${30}^{o}C$
• B. ${40}^{o}C$
• C. ${50}^{o}C$
• D. ${60}^{o}C$

Answer 1

Answer: (C)

${50}^{o}C$

Conversion of temperature is

${}^{\circ }F=\frac{9}{5}{\times }^{\circ }C+{32}^{\circ }{\Rightarrow }^{\circ }C=\frac{5}{9}{(}^{\circ }F-{32}^{\circ })$

For ${122}^{\circ }F$
${}^{\circ }C=\frac{5}{9}({122}^{\circ }-{32}^{\circ }){}^{}{}^{\circ }C=\frac{5}{9}\times {90}^{\circ }={50}^{\circ }$

So option $C$ is correct.
