What would scientists need kelvins to measure?
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...
Why is it important to convert it to kelvin or Celsius?
Kelvin is an absolute temperature, whereas both Celsius and Fahrenheit (as well as others) do not have an absolute zero value. The advantage of the Celsius scale is that one Celsius degree is the same as one degree on the Kelvin scale. As a result temperature changes are the same whether measured in Kelvin or degrees C. Besides, nobody apart from the US uses Fahrenheit anyway. Oh, yes, also Burma and Liberia.
Convert this temperature to the Kelvin scale 25 C?
25 degrees Celsius = 298.15 kelvin[K] = [°C] + 273.15
How do you convert 70 degrees Celsius into Kelvin scale?
You can convert any Celsius temperature to Kelvins. Just ADD 273.15 to it.
How does a degree Celsius and a Kelvin compare?
0 Kelvin is -273.15 oCelsius. There is no negative portion on the Kelvin scale. 1 Kelvin degree has the same magnitude as 1 Celsius degree. If the temperature drops 15 K that is the same as dropping 15 oC Note Kelvin does not use the degree symbol.
