Question

Convert ${32}^{\circ }C$ to Fahrenheit scale.

• A. ${109.6}^{\circ }F$
• B. ${89.6}^{\circ }F$
• C. ${70}^{\circ }F$
• D. ${99.6}^{\circ }F$

Answer 1

The correct option is B ${89.6}^{\circ }F$

Given, temperature in Celsius scale, $C={32}^{\circ }C$.
Let $F$ be the temperature in Fahrenheit scale and $C$ be the temperature in Celsius scale.
We know, $C=\frac{5}{9}(F-32)$
$\Rightarrow F=\left(\frac{C\times 9}{5}\right)+32$
$\Rightarrow F=\left(\frac{32\times 9}{5}\right)+32=57.6+32={89.6}^{\circ }F$
