What is \[{{19}^{\circ }}\text{ C}\]in Fahrenheit?

Hint: Both the Fahrenheit and the Celsius are the two different ways of measurement of temperature. We can convert the degree Fahrenheit to Celsius and also Celsius to Fahrenheit. We have a formula given by $Celsius=\dfrac{5}{9}\times (Fahrenheit-32)$. By using this formula, we can get the required answer. Always remember this formula for conversion as it will save your precious time in exams.

Complete answer:
Degree Celsius is the measure of temperature and degree Fahrenheit also another way of measuring temperature.
There are different ways of measurements used to measure temperature. Those are, Celsius, Fahrenheit and Kelvin. In the given problem they have asked to convert from degree Celsius to degree Fahrenheit. This can be done by using a
Conversion formula given by:
$Fahrenheit=\dfrac{9}{5}\times (Celsius)+32$
Now, they have asked to convert \[{{19}^{\circ }}\text{ C}\]in Fahrenheit, so by substituting the Celsius value we will get the required form of temperature,
Therefore, $Fahrenheit=\dfrac{9}{5}\times (19)+32$
We get, \[{{19}^{\circ }}\text{ C}\]= ${{66.2}^{\circ }}\text{ F}$
Hence, we can say that \[{{19}^{\circ }}\text{ C}\] is equal to ${{66.2}^{\circ }}\text{ F}$

Note:
Temperature conversion is a very basic need. It is not only used in our school but also in real life. Sometimes, when we move to some other country, we see that they have different units for temperature, so if we know the conversion formula, we can convert the temperature into the desired units within a few seconds. Also, sometimes in between the questions, we get different values of temperature which are given in different units and we need to convert them into one unit. This takes a lot of time and sometimes also gets wrong if we don’t know the correct formula. It will also help in entrance examinations where time and accuracy are the key to success.
