Because it is an absolute scale. There are no negative temperatures. With Kelvin, it makes sense to say that one temperature is twice another temperature, for example.
It has the same magnitude as kelvin.
Both Celsius and Kelvin.

An advantage of the Kelvin scale is that all the temperatures on this scale are positive. Another advantage is that the temperature in Kelvin is directly proportional to the total internal energy of the substance: if you double the internal energy, you will double the temperature in Kelvin.
This scale is mostly used in scientific applications.
The Celsius scale comes first, followed by the Kelvin scale, and then the Fahrenheit scale. This is in terms of historical development and general usage in the scientific community.
The Kelvin scale is based at absolute zero. The Kelvin scale was defined when the scientist William Thomson (1st Baron Kelvin) calculated the absolute minimum thermal energy an object can have. He decided to shift the Celsius scale so that 0 would be equivalent to having zero thermal energy (aka absolute zero).
The Kelvin scale is used for temperature measurement because it is an absolute scale based on thermodynamics. The zero point of the Kelvin scale, 0 K, corresponds to absolute zero where molecular motion ceases. This makes Kelvin ideal for scientific calculations and comparisons.
Lord Kelvin communicated about his new temperature scale, now known as the Kelvin scale, by publishing his findings in scientific journals and papers. He likely shared his discovery through letters and meetings with other scientists to explain the rationale and advantages of the new scale. The adoption of the Kelvin scale in scientific communities was gradual but eventually became widely accepted due to its clear and logical measurement of temperature.
In the context of temperature, K typically represents the Kelvin scale. The Kelvin scale is an absolute temperature scale where 0 K corresponds to absolute zero, the lowest temperature that can theoretically be reached. It is commonly used in scientific measurements and calculations.
The Kelvin scale is a temperature scale that starts at absolute zero, the lowest possible temperature where particles cease to move. It is commonly used in scientific contexts to measure temperature. On the Kelvin scale, water freezes at 273.15 K and boils at 373.15 K.
The SI unit is the Kelvin, but we use Celsius a lot too.
