Temperature scales are devices used to measure temperature at different points. A number of temperature scales are in use. These scales have a lower fixed point (LFP) which is the temperature of pure ice at one atmosphere pressure. It is also called as ice point.
Also, these scales have a upper fixed value (UFP) which is the temperature of steam at one atmosphere or atmospheric pressure. It is also called steam point.
The interval between the ice point and the steam point is divided into different numbers of divisions for different scales as written below (for the ones you are asked are temperature scales used currently)
Name of the scale used: Reaumur, it's symbol (for each degree) is °R, lower fixed point is 0°R, upper fixed point is 80°R and number of divisions are 80.
Name of the scale used: Celsius, it's symbol (for each degree) is °C, lower fixed point is 0°C, upper fixed point is 100°C and number of divisions are 100.
Name of the scale used: Fahrenheit, it's symbol (for each degree) is °F, lower fixed point is 32°F, upper fixed point is 212°F and number of divisions on the scale is 180.
Name of the scale is: Rankine, it's symbol (for each degree) is Ra, lower fixed point is 460 Ra, upper fixed point is 672 Ra and number of division on the scale is 212.
Name of the scale used: Kelvin, it's symbol (for each degree) is K, lower fixed point is 273 K, upper fixed point is 373 K and the number of divisions on the scale present is 100.
