Celsius
The world's most common temperature scale is Celsius. Abbreviated C, it is virtually the same as the old centigrade scale and therefore has 100 degrees between the melting point and boiling point of water, taken to occur at 0 and 100 degrees, respectively.
Kelvin
Temperature is a measure of the thermal energy of a system. Thus cooling can proceed only to the point at which all of the thermal energy is removed from the system, and this process defines the temperature of absolute zero. The Kelvin scale, also called the absolute temerature scale, takes its zero to be absolute zero. It uses units of kelvins (abbreviated K), which are the same size as the degrees on the Celsius scale.
Fahrenheit This anachronistic temperature scale, used primarily in the United States, has zero defined as the lowest temperature that can be reached with ice and salt, and 100 degrees as the hottest daytime temperature observed in Italy by Torricelli.
