Question

The average body temperature of a normal human body is $98.6{}^\circ F$. A patient checked his body temperature which reads $38{}^\circ C$. Help this patient to convert the body temperature in ${}^\circ F$ . Does he have a fever?

Answer 1

Hint: Fahrenheit and degree Celsius and kelvin are the three measuring units of temperature. The most commonly used unit of temperature on regular bases is Fahrenheit. But the researchers’ maximum times prefer to use kelvin for the study purpose of different experiments.
As per the given question,
Normal body temperature is $98{}^\circ F$
The temperature measured by the patient is $38{}^\circ C$

Formula used:
$F=\dfrac{9}{5}C+32$

Complete step-by-step answer:
Temperature is measured by an instrument lite thermometer. There are many different types of thermometers available in the market such as digital thermometer, infrared thermometer, strip-type thermometers, and so on. The most commonly used thermometer used around us is the mercury thermometer.
From the question, we know that the patient’s body temperature in Celsius is $38{}^\circ C$.
So by converting the temperature of the patient into Fahrenheit using the stander formula,
$F=\dfrac{9}{5}C+32$
By putting the value of temperature in Celsius:
$\begin{align}
  & F=\dfrac{9}{5}(38)+32 \\
 & \Rightarrow F=\dfrac{342}{5}+32 \\
 & \Rightarrow F=100.4{}^\circ F \\
\end{align}$
So the measured body temperature of the patient is $100.4{}^\circ F$in Fahrenheit.
As per the question it is mentioned that the normal human body temperature is \[98{}^\circ F\]. So from the calculation, we found that the temperature measured by the patient is $100.4{}^\circ F$ which is greater than the normal human body temperature.
Thus we can conclude that the patient is suffering from fever.

Note: Fahrenheit is used in medical fields as it provides almost 1.8 times more preciseness than the Celsius unit. As there are not many decimal places when the calculation is done in Fahrenheit it is easy to relate the air temperature and all us to compare small shifts in the temperature more accurately. While converting the temperature from Celsius to Fahrenheit it is important to take care of the values and the signs used as per the standard formula because a small human error can cause a huge calculation difference.
