Question

Convert ${185}^{o}F$ into Celsius.

• A. ${58}^{o}C$
• B. ${65}^{o}C$
• C. ${85}^{o}C$
• D. ${95}^{o}C$

Answer 1

Answer: (C)

${85}^{o}C$

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 ${185}^{\circ }F$

${}^{\circ }C=\frac{5}{9}({185}^{\circ }-{32}^{\circ }){}^{}{}^{\circ }C=\frac{5}{9}\times {153}^{\circ }={85}^{\circ }$

So option $C$ is correct.
