There are three different scales to measure temperature. These are the Celsius scale, the Fahrenheit scale and the Kelvin I scale.
Celsius scale : In the Celsius scale, the lower fixed point is j 0 °C, the upper fixed point is 100 °C, and the length of the thermometer between the lower fixed point and the upper j fixed point is divided into 100 equal parts.
Fahrenheit scale : In the Fahrenheit scale, the lower fixed point is 32 °F, the upper fixed point is 212 °F, and the length of the thermometer between the lower fixed point and the 1 upper fixed point is divided into 180 equal parts.
Kelvin scale : In the Kelvin scale, the lower fixed point is 273 K, the upper fixed point is 373 K, and the length of the thermometer between the lower fixed point and the upper fixed point is divided into 100 equal parts.
