What are the various units to measure temperature of substance?

Answer 1

There are really only two units that are widely used to describe temperature:

-- the Kelvin/degree Celsius, equal to 1/100 of the difference between water

freezing and water boiling;

-- the degree Fahrenheit/degree Rankine, equal to 1/180 of the difference between

water freezing and water boiling;

The Reaumer degree, equal to 1/80 of the difference between water freezing and

water boiling, was used in Europe until the late 18th Century. Its only modern use

is in the measuring of milk temperature in cheese production. It's used in some

Italian dairies making Parmigiano-Reggiano and Grana Padano cheeses and in

Swiss Alp cheeses.

Answer 2

The common units to measure temperature include Celsius (°C), Fahrenheit (°F), and Kelvin (K). Celsius is based on the freezing and boiling points of water, Fahrenheit is commonly used in the United States, and Kelvin is the unit used in scientific settings as it is based on absolute zero.
