Kelvin, celsius and fahrenheit are three types of what scales?

They are temperature scale.

Explanation:

Kelvin scale: It is the absolute scale to measure the temperature.

For Kelvin scale, the melting point of ice is 273 degree, the boiling point of water is 373 degree and the number of divisions between the melting point and the boiling point is 100.

For Celsius scale, the melting point of ice is 0 degree, the boiling point of water is 100 degree and the number of divisions between the melting point and the boiling point is 100.

For Fahrenheit scale, the melting point of ice is 32 degree, the boiling point of water is 212 degree and the number of divisions between the melting point and the boiling point is 180.
