Question

Highlight the different scales of temperature from one scale to another (Fahrenheit, Celsius, and Kelvin scales)

Accepted Answer

Scales of temperature:

A scale is marked on the thermometer. The temperature of the body in contact with the thermometer can be read on that scale. Three scales of temperature are in common in use. These are:

Celsius scale or centigrade scale
Fahrenheit scale
Kelvin Scale

Celsius scale:

On the Celsius scale, the interval between lower and upper fixed points is divided into 100 equal parts. The lower fixed point is marked as 0°C and the upper fixed point is marked as 100°C.

Fahrenheit scale:

On the Fahrenheit scale, the interval between lower and upper fixed points is divided into 180 equal parts. The lower fixed point is marked as 32°F and the upper fixed point is marked as 212°F.

Kelvin scale:

In SI units, the unit of temperature is Kelvin (K) and its scale is called the Kelvin scale of temperature. The interval between lower and upper fixed points is divided into 100 equal parts. Thus, a change in 1°C is equal to a change of 1K. The lower fixed point on this scale corresponds to 273 K and the upper fixed point is referred to as 373 K. The zero on this scale is called the absolute zero and is equal to -273°C.
