Answer
The three common temperature scales are:
1. Kelvin $(K)$
2. Celsius $(C^{o})$
3. Fahrenheit $(F^{o})$
Yes, the size of a degree differs among them.
Work Step by Step
The size of degree and scale of each is different. At $0^{o}C$ you see the freezing point of water, but at $0K$ you see absolute zero.
Note that a degree symbol $(^{o})$ is not used for Kelvin measurements.
