The kelvin (symbol: K) is a unit increment of temperature and is one of the seven SI base units. The Kelvin scale is a thermodynamic (absolute) temperature scale referenced to absolute zero, the absence of all thermal energy. So by definition, the temperature of a substance at absolute zero is zero kelvin (0 K). The secondary reference point on the Kelvin scale is the triple point of water (0.01 degrees Celsius). The Kelvin scale is the difference between these two reference points, with the kelvin defined as one 273.16th of this scale. The Kelvin scale and the kelvin are named after the Belfast-born physicist and engineer William Thomson, 1st Baron Kelvin (1824-1907), who wrote of the need for an "absolute thermometric scale". Unlike the degree Fahrenheit and degree Celsius, the kelvin is not referred to as a "degree", nor is it typeset with a degree symbol; that is, it is written K and not °K. The kelvin and the degree Celsius are often used together, as they have the same interval, and 0 kelvin is −273.15 degrees Celsius.short answer - temperature.Kelvin is the absolute temperature scale, with the same size degree as Celsius, but with zero set at 'absolute zero' - the temperature you can't go lower than...
"K" stands for Kelvin. There is a Kelvin thermometer, different from Celsius and Fahrenheit.Answer:Kelvin is a temperature scale named after Lord Kelvin (1824-1907), who wrote of the need for an "absolute thermometric scale".. Each degree Kelvin is the same size as a Celsius degree and 1.8 times as big as a Fahrenheit degree. The starting point for the Kelvin scale is absolute zero (0oK = -273oC or -460oF)
Kelvin Scale.
Celsius and Kelvin scales use the same size unit or "degree." But Kelvin has its zero point at absolute zero rather than the freezing point of water. Absolute zero (zero K) is about -273.15° Celsius.To convert Celsius to Kelvin, add 273.15. For example 100° C is 373.15 kelvins.To convert kelvins to Celsius, subtract 273.15. For very large numbers, such as 5000 K, the value (4726.85° C) is not going to be that different.
If the temperature is 1K then it would be -272oC, or -457oF. Each degree of Kelvin is equal to each degree of Celsius, they just have a different stating point. 0 degrees Celsius is the freezing point of water, whilst 0 degrees Kelvin is absolute zero. Which would be approximately -273 degrees Celsius.
