Why does Kelvin (temperature unit) not have “degrees” like Celsius or Fahrenheit?

Question

Or probably the other way around, why do Celsius and Fahrenheit have “degrees” in its unit?

Answer 1

A degree is a change in temperature that is measured against a scale. The size of a degree is arbitrary. For example, originally the Celsius scale was set such that 0°C was the freezing point of water, while 100°C is its boiling point.

Kelvin is different because it’s an absolute scale. 0K is absolute zero — the point at which gas molecules have no thermal energy.
