(N/A) There are three common temperature scales: Celsius $(^{\circ}C)$,Fahrenheit $(^{\circ}F)$,and Kelvin $(K)$.
$(1)$ Relation between Celsius and Kelvin scales:
If $T_{C}$ is the temperature in Celsius and $T$ is the temperature in Kelvin,the relationship is given by:
$T = T_{C} + 273.15$
$(2)$ Relation between Celsius and Fahrenheit scales:
If $T_{F}$ is the temperature in Fahrenheit and $T_{C}$ is the temperature in Celsius,the relationship is given by:
$T_{F} = \frac{9}{5} T_{C} + 32$
$(3)$ General relation:
The general relation between these scales is given by the formula:
$\frac{T_{C} - 0}{100} = \frac{T_{F} - 32}{180} = \frac{T - 273.15}{100}$
These scales are compared based on fixed points like the ice point (freezing point of water) and the steam point (boiling point of water) at atmospheric pressure. The Kelvin scale is an absolute scale where $0 \ K$ is the absolute zero temperature,which is the lowest possible temperature.
