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.
The Kelvin scale is based on absolute zero, the lowest possible temperature where particles have minimal energy. This makes Kelvin more suitable for scientific calculations as it has a set zero point. Celsius is based on the freezing and boiling points of water, which can vary at different atmospheric pressures, while Kelvin is not affected by this variability.
I 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'?
Because 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.
Probably 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.
Kelvin 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.
It 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.
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 unit symbol for the SI unit that represents temperature?
The unit symbol for the SI unit that represents temperature is K, which stands for Kelvin.
What is the SI unit of temperature?
The unit is the Kelvin. Zero on the Kelvin scale is the coldest possible temperature, absolute zero. The scale increases by the same degree intervals as the Celsius scale but since Kelvin starts at absolute zero, the values are all higher. For example, it is 273.15 K when it is 0°C (Celsius). Kelvin "K" It is KELVIN!!!!! Either Kelvin, or Celsius. Both are used with the SI K degreeskelvin
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 SI unit for temperature?
kelvin
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 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 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 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.
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 base unit for temperature called?
The SI base unit for temperature is called the Kelvin (K).
Is kelvin a fundamental unit?
The kelvin is not considered a fundamental unit in the International System of Units (SI). It is a derived unit that is based on the fundamental unit of temperature in SI, the degree Celsius. The kelvin is used to measure thermodynamic temperature.
What is the unit symbol for the SI unit that represents temperature?
The unit symbol for the SI unit that represents temperature is K, which stands for Kelvin.
What is the SI unit of temperature?
