Celsius and Fahrenheit are relative scales which are compared with freezing and boiling points of water. While kelvin is not relative and is an absolute scale. From graphical representation of Charles's when one extrapolate the graph straight, it will touch the zero volume at -273.16 Celsius or OK. This OK is the start or emergence of kelvin scale which is not related to anything, but absolute.

∙ 12y agoI think it's because the scale is absolute and not relative. Celsius and Fahrenheit are both relative scales based on the freezing and boiling points of water - which change with altitude. Kelvin starts at absolute zero (the "temperature" at which there is no molecule movement) which is a, theoretically, absolute/fixed number.
AnswerFor the same reason that no other SI unit has a degree sign -why would it? You wouldn't say '30-degrees ampere', so why would you say '30-degrees kelvin'?
Wiki User
∙ 12y agoBecause there's no temperature below zero degrees Kelvin.
AnswerThere is no degree (o) symbol used with the kelvin scale for the same reason that there is no degree symbol for any other SI unit -there is simply no reason to have one.

∙ 11y agoProbably the creators of the SI decided that Kelvin should be treated just like any other unit, such as meters or Ampère.
Other comments:
They used to be called degrees kelvin until they were changed to just Kelvin in 1967. Why? Because that has been the official agreement ever since.

∙ 13y agoKelvin is the absolute thermometric scale, which corresponds with absolute zero, or the point at which matter has no kinetic energy and ceases movement. Celsius is based only on the properties of water, rather than all substances. Additionally, the Kelvin scale links temperature to the SI. For example, one milliliter in one cubic centimeter.

∙ 13y agoIt doesn't have one because the official Standard Unit(S.I.) is Kelvin, symbol K. ( not like Celsius=> degrees, symbol oC)

Is Newton or Kelvin is the SI unit for temperature?
Yes kelvin is a si base unit. Kelvin is a fundamental unit of SI for thermodynamic temperature.
What si unit to measur temperature?
Temperature is measured in degrees Celsius (oC), Fahrenheit (oF) or Kelvin (oK) * * * * * Degree Fahrenheit is not an SI unit for measuring temperature.
Is degree celsius a si unit of measure?
The base unit for temperature is the kelvin. One degree celsius is the same as one kelvin, because kelvin starts at absolute zero, degrees celsius is kelvin plus 273.15. Celsius is used for most non-technical uses. Kelvin is just kelvin, not degrees kelvin.
Can temperature be used in si units?
The SI unit of temperature is the Kelvin. It's the same size as the Celsius degree.
What is the SI basic unit of temperature?
Basic unit of temperature is kelvin or celsius. 0 C = 273.15 K
What is SI unit for temperature?
kelvin

What is the Si temperature unit?
degrees celsius
Si unit temperature?
The SI unit of temperature is Kelvin, but degrees Celsius is a derived SI unit for temperature and more commonly used.
What are two scales scientists use as to measure temperature and what is the official SI unit for temperature?
Scientists use celsius and kelvin. The SI unit for temperature is Celsius.
What si unit to measur temperature?
Temperature is measured in degrees Celsius (oC), Fahrenheit (oF) or Kelvin (oK) * * * * * Degree Fahrenheit is not an SI unit for measuring temperature.
SI unit of F?
The temperature in Fahrenheit is no SI unit. Use kelvin or degrees Celsius instead.
Is degree celsius a si unit of measure?
The base unit for temperature is the kelvin. One degree celsius is the same as one kelvin, because kelvin starts at absolute zero, degrees celsius is kelvin plus 273.15. Celsius is used for most non-technical uses. Kelvin is just kelvin, not degrees kelvin.
What is the SI unit for temperature?
Kelvin is the SI unit for thermodynamic temperature. symbol: K (there are no degrees, unlike °C and °F).
What is the nonSI unit for temperature?
The SI unit for temperature is Kelvin.Kelvin = Celsius + 273Fahrenheit and Celsius are non SI units, however, Celsius is used in science as it is so easily converted to Kelvin.
What is 43ºC in Kelvin?
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. The answer in Kelvin is 316.15Kelvin is the SI unit for temperature.
