The only difference between these two scales is where the zero mark is located.

#### Explanation:

The temperature on the Kelvin scale is simply the temperaure of the Celsius scale plus 273.15.

${T}_{\text{Kelvin" = T_"Celsius}} + 273.15$

In other words, if you move the 0 mark on a Celsius scale to 273.15, you get the Kelvin scale.

This means that the starting point of the Kelvin scale, $\text{0 K}$, which is known as absolute zero, would correspond to

${T}_{\text{Celsius" = T_"Kelvin}} - 273.15$

${T}_{\text{Celsius" = 0 - 273.15 = "-273.15"^@"C}}$

You can use water's freezing and boling temperatures as examples of how the Kelvin scale relates to the Celsius scale.

The freezing point of water is ${0}^{\circ} \text{C}$. Expressed in Kelvins, this temperature would be equal to

${T}_{\text{Kelvin" = 0^@"C" + 273.15 = "273.15 K}}$

The boling point of water is ${100}^{\circ} \text{C}$. Its Kelvin value will be

${T}_{\text{Kelvin" = 100^@"C" + 273.15 = "373.15 K}}$
