Question

What is 29 degrees Celsius in Fahrenheit?

Answer 1

Hint: In the above question, we are given a temperature value in the degrees Celsius unit, equal to $29$ degree Celsius, which has to be converted into the degrees Fahrenheit unit. For this, we need to use the unit conversion formula from the degrees Celsius to the degrees Fahrenheit, which is given by the expression $^{\circ }F=\dfrac{9}{5}\left( ^{\circ }C \right)+32$. Thus, we need to multiply the given temperature by nine, divide it by five, and then finally add $32$ to finally get the temperature in the degrees Fahrenheit.

Complete step-by-step solution:
The value of the temperature given in the above question is $29$ degrees Celsius. According to the question, this has to be converted to degrees Fahrenheit. We know that the unit conversion formula for converting the temperature in the degrees Celsius to the degrees Fahrenheit is given by
${{\Rightarrow }^{\circ }}F=\dfrac{9}{5}\left( ^{\circ }C \right)+32$
Substituting the given temperature of \[{{29}^{\circ }}C\] in the above formula, we get
$\begin{align}
  & {{\Rightarrow }^{\circ }}F=\dfrac{9}{5}\left( 29 \right)+32 \\
 & {{\Rightarrow }^{\circ }}F=\dfrac{261}{5}+32 \\
\end{align}$
On dividing, we get
\[\begin{align}
  & {{\Rightarrow }^{\circ }}F=52.2+32 \\
 & {{\Rightarrow }^{\circ }}F=84.2 \\
\end{align}\]
Hence, the given temperature in the degrees Fahrenheit is equal to \[{{84.2}^{\circ }}F\].

Note: From the unit conversion formula from the degrees Celsius to the degrees Fahrenheit, which is $^{\circ }F=\dfrac{9}{5}\left( ^{\circ }C \right)+32$, we can derive the opposite relation as $^{\circ }C=\dfrac{5}{9}\left( ^{\circ }F \right)-32$. Students are generally confused between these two relations. For this, we need to remember the fact that the temperature in the degrees Fahrenheit is always greater than that in the degrees Celsius. Also, we must follow the BODMAS rule, according to which we must first multiply the temperature by $\dfrac{9}{5}$ and then add $32$ to it.
