Scientific comparisons are done in Celsius, but outdoor readings are still announced, (and body temperatures still recorded) as temperatures on the Fahrenheit scale.
273 k
This is beacause it is in the absolute kelvin scale with -273 as the initial temperature. Also known as the absolute temperature.
Not necessarily. Celsius is a temperature scale and can describe a large range of temperatures.
Celsius and Kelvin scale are also valid and useful. Celsius scale is a conventional scale based on the freezing and boiling point of water. Kelvin scale is an absolute, scientific, based on thermodynamics scale.
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.
Scientific comparisons are done in Celsius, but outdoor readings are still announced, (and body temperatures still recorded) as temperatures on the Fahrenheit scale.
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.
Kelvin
The Kelvin scale is used to measure absolute temperature, i.e., temperature from absolute zero. The way it is defined, there are no negative temperatures on the Kelvin scale.The Kelvin scale is used to measure absolute temperature, i.e., temperature from absolute zero.

273 k
This is beacause it is in the absolute kelvin scale with -273 as the initial temperature. Also known as the absolute temperature.
Because differences (or changes) in temperatures need to be measured on an absolute scale not a scale with its zero at an arbitrary point.
The two most common temperature scales are the Fahrenheit scale and the Celsius scale. However, the Kelvin scale is also used, primarily in science, to prevent negative temperatures.
The scale we use for temperature is "degrees" (°). There are three temperature scales that are used today. The Kelvin (K) scale is used by scientists and for astronomical temperatures. The Celsius scale (°C) is used in most of the world to measure air temperatures. In the United States, the Fahrenheit scale(°F) is used to measure temperatures at or near the surface.
The metric temperature scale is called the Celsius scale. The scale divides the range of temperatures between freezing and boiling at standard atmospheric condition into 100 equal parts.
It can be used with any temperature. However the Kelvin scale (centigrade based on absolute zero) is often used for very cold temperatures, or for very hot temperatures, where it is practically the same as Celsius.
