Celsius and Kelvin scales have the same unit, but they start at different temperatures. 0 Celsius is the freezing pt of water, but 0 Kelvin is absolute zero (the coldest temperature possible)

Celsius and Kelvin
The Celsius and Kelvin temperature scales have the same size unit. One degree Celsius is equal in size to one Kelvin, with the only difference being their zero points.
Both Celsius and Kelvin scales have the same size degree (1 degree Celsius is equivalent to 1 Kelvin). The zero point on both scales is also set at the same temperature, absolute zero, which is the coldest possible temperature at which all molecular movement stops.

The fundamental interval on the thermodynamic scale is the Kelvin scale, where the interval between each degree is the same size. This scale begins at absolute zero and is used to measure temperature in thermodynamics.
Kelvin and Celsius
The 'kelvin' and the celsius 'degree' are identical temperature intervals ... they are the same size. The marks on the kelvin thermometer and the marks on the celsius thermometer are the same distance apart. Both scales have 100 divisions between the freezing and boiling temperatures of water, but the scales start at different places. (Kelvin starts at 'absolute zero', celsius starts at the freezing temperature of water.) The graphs of these two scales are parallel lines. The graphs never intersect, meaning that there is no temperature where kelvin and celsius are the same number.
The three temperature scales (Fahrenheit, Celsius, Kelvin) will meet at the temperature of -40 degrees, which is equivalent on all three scales. At this temperature, -40 degrees Celsius is equal to -40 degrees Fahrenheit and approximately 233 Kelvin.
The two temperature scales do not have the same unit size. The difference between 80 and 90 ºF is not the same size as between 80 to 90 ºC. Celsius = (Fahrenheit - 32) x 5/9
The thermodynamic temperature scales are based on the third law of thermodynamics:The entropy of a system approaches a constant value as the temperature approaches zero. The entropy of a system at absolute zero is typically zero, and in all cases is determined only by the number of different ground states it has.The two commonly used thermodynamic temperature scales are Kelvin (K), which has temperature increments the same size as Celsius and Rankine (°R), which had temperature increments the same size as Fahrenheit.The thermodynamic temperature scales are further defined by extrapolation of the values PV at given temperatures as pressure approaches zero and thus the ideal gas law becomes a better and better approximation.
