What is the Kelvin scale based on?

From there, the scale increases by degrees that are the same size as Celsius degrees. It is a scale that is based on energy content, rather than on arbitrary temperature values like the other two scale (based on water). Water freezes at the value 273.15 and boils at 373.15 Kelvin. read more

The Kelvin scale was also influenced by the Carnot engine, a theory that examines the relationship between pressure, work and temperature. It is one of the fundamentals of physics and thermodynamics and is a measure of the efficiency of an engine. read more

The Kelvin scale is an absolute thermodynamic temperature scale using as its null point absolute zero, the temperature at which all thermal motion ceases in the classical description of thermodynamics. The kelvin (symbol: K) is the base unit of temperature in the International System of Units (SI). read more

They are both based on physical properties of water. The only difference between them is the zero of each scale - the zero of kelvin scale is the absolute zero temperature and the zero of Celsius scale is the melting point of water at standard atmospheric pressure. read more
