How do you convert ${{50}^{\circ }}C$ to Fahrenheit?

Hint: In the US customary system of measurement, the most common units of distance are inches, feet, yards, and Fahrenheit. The relation between $^{\circ }C$ and $^{\circ }F$ is $F=1.8C+32$ where we have considered the values in their unit’s name. We use the formula to find the temperature of ${{50}^{\circ }}C$ into Fahrenheit.

Complete step-by-step answer:
We need to convert the temperature by changing its unit from $^{\circ }C$ and $^{\circ }F$.
We find the relation between $^{\circ }C$ and $^{\circ }F$ where $F=1.8C+32$, values taken in their unit’s name.
We already have that in unitary system. The unitary method is a method in which we find the value of a unit and then the value of a required number of units. The unitary method is also used to find the value of a single unit from a given multiple.
We need the equivalent temperature of ${{50}^{\circ }}C$. We are converting $^{\circ }C$ to $^{\circ }F$.
We put the value of $C=50$ in the relation of $F=1.8C+32$.
So, $F=1.8\times 50+32=90+32=122$.
Therefore, ${{50}^{\circ }}C$ is equivalent to ${{122}^{\circ }}F$.

Note: The $^{\circ }C$ and $^{\circ }F$ are units of measurement for temperature in both the US customary units and the British systems of measurement. This unit is used in the particular regional measurement units. It can also be changed to other common measurement units using the relation in that system.
