Q.A patient's body temperature is recorded as $102\,^\circ\text{F}$ on a clinical (Fahrenheit) thermometer. Convert this reading to the Celsius and Kelvin scales, using $C = \dfrac{5}{9}(F-32)$ and $K = C + 273$.

Temperature is measured on the Celsius, Fahrenheit, or (SI, absolute) Kelvin scale, each fixed by two reference points (the ice point and steam point of water for Celsius/Fahrenheit; absolute zero for Kelvin) divided into a chosen number of equal degrees. The three scales are related by $\dfrac{C}{5} = \dfrac{F-32}{9} = \dfrac{K-273}{5}$, allowing any reading on one scale to be converted to either of the other two.
