25 degrees Celsius = 298.15 kelvin
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...
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.
25 degrees Celsius = 298.15 kelvin[K] = [°C] + 273.15
You can convert any Celsius temperature to Kelvins. Just ADD 273.15 to it.
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.
If the normal body temperature on the temperature scale is 310, this means the temperature scale is using Kelvin. To convert Celsius to Kelvin you just need to add 37 and the normal body temperature is 273 Celsius.
The SI unit of absolute temperature is the Kelvin, not the degree.
Kelvin is a temperature scale, like Fahrenheit or Centigrade. It is generally used in scientific contexts. One degree Kelvin is equal to one degree Centigrade. In order to find the temperature in Kelvin, I have provided the following equations. If you have a temperature in Fahrenheit and want to know it in Kelvin, it is easiest to convert to Centigrade first. (Fahrenheit Temperature - 32) X (5/9) = (Centigrade Temperature) If you have a Centigrade temperature and want to know it in Kelvin, you can convert it directly to Kelvin. (Centigrade Temperature + 273) = (Kelvin Temperature) The reason for the 273 is that scientists wanted the Kelvin scale to begin at Absolute Zero. Thus, Absolute Zero is 0 K and -273 degrees Centigrade. Since, as I stated above, one degree Centigrade is equal to one degree Kelvin, this equation works. If you want to convert back from Kelvin, the following equations may be used. (Kelvin Temperature -273) = (Centigrade Temperature) And if you're asked to report the temperature in Fahrenheit, use (Centigrade Temperature X (9/5)) +32 = (Fahrenheit Temperature) It should be noted that you do not include a degree symbol when you report a Kelvin temperature.
Because when expressing absolute temperature using the Kelvin scale, the unit of temperature is not the "degree", it's the "Kelvin". The "Kelvin" is a unit of temperature equal to one Celsius degree. There's no such thing as a "Kelvin degree".
No degree sign is used on the Kelvin scale.
The relationship between Kelvin and Celsius scale is K=C+273. 15. Where K is Kelvin temperature and C is Celsius temperature. Each degree on the Kelvin scale equals the same degree in Celsius scale differing only in the zero value. The freezing point of water and absolute zero are the zero values of Celsius and Kelvin scale respectively.
To convert form Centigrade (= Celsius) to Kelvin, add 273.
The "Kelvin" scale, which uses the same size of degree as Celsius, but with a zero value at absolute zero. (on the Celsius scale, absolute zero is -273.15° C) There are no negative temperature values on the Kelvin scale.
Add 273.15
Kelvin is the SI unit for temperature. Celsius is usually used in metric systems. 0 degree celsius is 273.15 Kelvin. Kelvin increases equally with celsius. So to convert celsius to kelvin, we just add 273.15 to celsius.
To convert any temperature to the kelvin scale, when its in oC add on 273. so in answer to your question, -146oC = 127K
CELSIUS plus 273.15 = KELVIN -146 +273.15 = + 127.15 Kelvin
