This is beacause it is in the absolute kelvin scale with -273 as the initial temperature. Also known as the absolute temperature.

How do scientists use the kelvin scale?
Quite often, all temperatures are expressed in Kelvin. Sometimes Centigrade (= Celsius) is used alternately, though.
What temperature scale places zero at the point where all atomic and molecular motion ceases?
On the Kelvin scale, zero is the temperature at which there is no atomic or molecular motion.
Why was kelvin scale was made?
The Kelvin temperature scale (K) was developed by Lord Kelvin in the mid 1800s. The zero point of this scale is equivalent to -273.16 °C on the Celsius scale. This zero point is considered the lowest possible temperature of anything in the universe. Therefore, the Kelvin scale is also known as the "absolute temperature scale". At the freezing point of water, the temperature of the Kelvin scale reads 273 K. At the boiling point of water, it reads 373 K. Whereas the Kelvin scale is widely used by scientists, the Celsius or Fahrenheit scales are used in daily life. These two scales are easier to understand than the large numbers of the Kelvin scale. Could you imagine waking up to your radio and hearing the DJ give a weather report like this: "It's going to be a beautiful day today with sunny skies and a balmy temperature of 297 K!" That's 24 °C or 75 °F.
What happens on the Kelvin scale at 0 K?
nothing! all motion stops.
Why boiling points of gases are negative?
Negative values for the boiling points of gas are the result of using temperature scales, either Fahrenheit or Celsius, which do not begin at the true zero of temperature, which is the point of no heat. Only the Kelvin scale begins with the true zero, also known as absolute zero. Zero degrees Kelvin is equal to minus 273 degrees Celsius. If the boiling points of gas are given in Kelvins, then they are always positive. There are no negative degrees in the Kelvin scale. In the Celsius scale, zero is defined as the freezing point of water. Since the freezing point of water is hotter than the boiling point of most gases, you therefore get these negative numbers for the boiling point of gases, in Celsius.
What advantage does the Kelvin scale have for scientific measurements?
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.
What is it called when temperatures at which all motion of particles is stopped?
It is absolute zero on the Kelvin or thermodynamic scale.
How do scientists use the kelvin scale?
Quite often, all temperatures are expressed in Kelvin. Sometimes Centigrade (= Celsius) is used alternately, though.
What is -100 degrees in kelvin?
100 °C is equal to 373.15 KThe Kelvin scale uses the same degree interval as Celsius, but has its zero point at Absolute Zero (-273.15 °C), so all Kelvin temperatures are 273.15 degrees higher than the Celsius temperature. Kelvin temperatures do not use the ° sign or the word "degrees", as this is understood.Whatever it is in Celsius add 273.15 and it equals Kelvin. 100 Celsius is 373.15 Kelvin
What is the zero on the Kelvin scale?
It is Absolute Zero. On the Kelvin scale there are no negative numbers...so therefore absolute zero on the kelvin scale is zero. All we might add is that absolute zero is --273.15 degrees C.
When and what are some of the major points on the Kelvin scale?
On the Kelvin scale, 0 is absolute zero, which is the theoretical temperature at which all atomic motion stops. This is not a possible temperature to reach, not even in deep space. There is no "below zero" on the Kelvin scale. Water melts at 273 Kelvin, and boils at 373 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
What temperature scale places zero at the point where all atomic and molecular motion ceases?
On the Kelvin scale, zero is the temperature at which there is no atomic or molecular motion.
What is a temperature scale?
The metric system (SI) measurement of temperature is the "degree Kelvin"(K). These are the same unit as Celsius degrees, except that the Kelvin scale has its lower end at "absolute zero" (-273.15°C) so that a measured temperature is 273.15° higher in K than in Celsius.Hence the freezing point of water at standard pressure is 0° C , or 273.15 K and the boiling point is 100°C or 373.15° K.For everyday usage, the Celsius scale is used. When scientific data is reported, Kelvin is used. Kelvin temperatures do not use the degree mark.
Why Fahrenheit and centigrade are degrees while kelvin is not?
Because Kelvin is a scale reflection of reality, of what heat is; the amount of molecular and atomic movement. At 0 Kelvin, a temperature not yet reached, all movement stops and their is no upper limit to the Kelvin scale either.
What are all the the temperatures in the metric system?
In the metric system we use Kelvin and Celsius.
What kind of scale is used to measure mass?
mass
