Because the Kelvin scale is an absolute scale.
In the context of thermodynamics, 2 K is twice as "hot" as 1 K. And 3 K is three times as "hot". That is not true of the Celsius or Fahrenheit (or other temperature) scales.

Why do scientists use the Kelvin and Celsius scale rather than the Fahrenheit scale?
Celsius is a very accurate measurement between the freezing and boiling points of water. 0 being freezing, and 100 boiling. Kelvin is the measurement of absolute zero, where particles stop moving altogether. Kelvin has the same conversion rating, only 0 Kelvin is -273 degrees Celsius. The Kelvin scale is an absolute scale. This means that 2 K is twice as hot as 1 K and so on. Neither the Celsius nor the Fahrenheit scales do that. The Centigrade (or Celsius scale are based on the freezing and boiling points of water (at normal pressure), the Fahrenheit scale was not: the 0 was the lowest temperature attained by ice and salt.
Why is Celsius zero called absolute zero?
It isn't. "Absolute zero" is zero on the Kelvin scale, 273.15 degrees colder than zero Celsius.
What would scientists need kelvins to measure?
The kelvin (symbol: K) is a unit increment of temperature and is one of the seven SI base units. The Kelvin scale is a thermodynamic (absolute) temperature scale referenced to absolute zero, the absence of all thermal energy. So by definition, the temperature of a substance at absolute zero is zero kelvin (0 K). The secondary reference point on the Kelvin scale is the triple point of water (0.01 degrees Celsius). The Kelvin scale is the difference between these two reference points, with the kelvin defined as one 273.16th of this scale. The Kelvin scale and the kelvin are named after the Belfast-born physicist and engineer William Thomson, 1st Baron Kelvin (1824-1907), who wrote of the need for an "absolute thermometric scale". Unlike the degree Fahrenheit and degree Celsius, the kelvin is not referred to as a "degree", nor is it typeset with a degree symbol; that is, it is written K and not °K. The kelvin and the degree Celsius are often used together, as they have the same interval, and 0 kelvin is −273.15 degrees Celsius.short answer - temperature.Kelvin is the absolute temperature scale, with the same size degree as Celsius, but with zero set at 'absolute zero' - the temperature you can't go lower than...
Is a kelvin equal to a Celsius?
Units are the same. Temperatures in kelvin are 273 more than celsius temperatures.
Is 100 degrees Kelvin the same as 100 degrees Celsius?
No. (Note that you don't say "100 degree Kelvin"; "100 Kelvin" is correct.) 100 Kelvin is about 273 degrees (Kelvin or Celsius) less than 100 degrees Celsius.
Why does the percent error calculation have to be performed in celsius rather than kelvin?
That is just utter nonsense. Kelvin is the absolute scale so percentages should be calculated in Kelvin and not Celsius.
Celsius degree larger than a kelvin degree?
No, the interval of one degree is identical in the Celsius and in the Kelvin scale. However Kelvin starts at absolute zero (-273.15 °Celsius) while 0 °Celsius is 273.15 Kelvin.

Why do you use kelvin scale?
Kelvin Scale is an absolute temperature scale. This means that it starts at a different point than Celsius, its counterpart. This is why you must add 273.15 to a Celsius temperature in order to get a Kelvin temperature. The Kelvin scale starts at absolute zero whereas Celsius starts at the freezing point of water. Kelvin is used more often in science such as in the ideal gas equation. It is more convenient to use it than Celsius when dealing with very cold temperatures and with things like the Perfect Gas Laws which reference absolute zero.
Why do you use kelvin instead of Celsius?
Kelvin and Celsius are both units used to measure temperature. Celsius is typically used in countries that use the metric system. Kelvin is used in a scientific or academic setting, because it's scale is more precise than Celsius.
Is one celsius degree larger than a kelvin?
The interval of one degree is identical in the Celsius and in the Kelvin scale; but if you understand 1 0C this temperature is equivalent to 274,15 K.
Which is larger a Celsius degree or a Kelvin?
Hi when dealing with the kelvin scale the numbers will be larger than in celsius because when you are converting from celsius to kelvin you need to add 273.15 on to the temperature in celsius. This is because zero celsius is 273.15 kelvin.
Is a kelvin more accurate than a celsius?
No, they both are comparable. The Kelvin scale starts at absolute zero and is used in scientific laboratories. Celsius is for general use and set 0 and 100 as melting and boiling point of water respectively. To convert from C to K or vice-versa, add or subtract 273.15 to or from temperatures..
What is the difference between the Celsius scale and the Kelvin scale of temperature?
The Celsius scale is an interval scale which means that the difference between 0 deg C and 10 deg C is the same as the difference between 10 deg C and 20 deg C. However, the zero of this scale is arbitrary which means that 20 deg C is not twice as hot as 10 deg C..The zero point of the Kelvin scale is not arbitrary: it is the point at which thermodynamic energy is zero and so the scale more versatile than an interval scale: it is a ratio scale and this means that 20 K is twice as hot as 10 K.
How do you use kelvin scale?
The Kelvin scale measures temperature. You can use it the same way you would use the Fahrenheit scale or the Celsius scale, but it also has an additional use. Since the Kelvin scale starts at the true zero of temperature, when there is no random thermal motion, rather than starting at some arbitrary point such as the freezing point of water (Celsius) or the coldest temperature that was obtainable in the laboratory at the time the Fahrenheit scale was first devised, you can make much more meaningful comparisons in Kelvin. If something has twice the temperature in Kelvin than something else has, then it actually is twice as hot. That is not true of other temperature scales. 20oC is not twice as hot as 10oC. But 20oK actually is twice as hot as 10oK.
Why is Celsius zero called absolute zero?
It isn't. "Absolute zero" is zero on the Kelvin scale, 273.15 degrees colder than zero Celsius.
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
