The meaning of KELVIN is the base unit of temperature in the International System of Units that is defined by setting the fixed numerical value of the Boltzmann constant to be 1.380649 x 10—23 joules per kelvin and that is equal to 1/273.16 of the Kelvi
1.A unit of absolute temperature equal to 1/273.16 of the absolute temperature of the triple point of water. One kelvin degree is equal to one Celsius degree. See Table atmeasurement. 2.KelvinA temperature scale in which zero occurs at absolute zero and each degree equals one kelvin. Water...
Fahrenheit and Celsius Temperature Scales Absolute Zero and the Kelvin ScaleEnergy, Thermal
Celsius is a temperature scale based on the freezing point (0°C) and boiling point (100°C) of water at sea level. Kelvin, however, begins at absolute zero, the theoretical lowest possible temperature, and has units the same size as Celsius degrees. 6 The Celsius scale is commonly used...
The zero point of the Kelvin scale is absolute zero, which is when particles have minimum kinetic energy and cannot get colder. Each unit (a degree, in other scales) is 1 part in 273.16 parts of the difference between absolute zero and the triple point of water. This is the same size ...
Kelvin is a temperature scale designed so that zero degrees K is defined as absolute zero (at absolute zero, a hypothetical temperature, all molecular movement stops - all actual temperatures are above absolute zero) and the size of one unit is the same as the size of one degree Celsius. ...

0 kelvins are equal to −273.15 degrees Celsius, which is the point of absolute zero. The kelvin is the SI base unit for temperature in the metric system. Kelvins can be abbreviated as K; for example, 1 kelvin can be written as 1 K. The kelvin scale is different from other temp...
The kelvin (symbol: K) is the SI unit of temperature, and is one of the seven SI base units. It is defined by two facts: zero kelvins is absolute zero (when molecular motion stops), and one kelvin is the fraction 1/273.16 of the thermodynamic temperature of the triple point of ...
A scale of temperature beginning at absolute zero (-273.15°C). Each degree, or kelvin, has the same value as one degree on the Celsius scale. On the Kelvin scale water freezes at 273.15 K and boils at 373.15 K. See Note at Celsius. The American Heritage® Student Science Dictionary,...
