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.

Either - it all depends what you learnt when growing up, or have adapted to as you've grown older. The Fahrenheit scale is almost twice the size of the Celsius scale (between freezing and boiling on Celsius there are 100 degrees, but on the Fahrenheit there are 180 degrees) meaning that smaller temperature differences show up as a larger difference with the Fahrenheit scale than with the Celsius scale. They are just as easy as each other, though scientists prefer Kelvin which has the same unit differences as Celsius but starting with 0 K = -273.15oC (water freezes at 273.15 K and boils at 373.15 K). The Fahrenheit scale was originally intended to be 0oF = freezing point of brine, nominally 32oF = freezing point of water and 96oF = normal body temperature, but later scientists redefined the scale slightly so that water did freezer at exactly 32o F which made body temperature 98.4oF.

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.

This has been answered twice recently: F=1.8 C + 32

Neither of them are absolute scales so that 2 degrees is not twice as warm (hot) as 1 degree. 10 degrees is not ten times as hot as 1 deg.

A Fahrenheit thermometer will give a reading that is twice that of a Celsius thermometer at -40 degrees, as this is the point where the two temperature scales intersect.

By the Celsius scale, yes. This is not necessarily the case when considering Fahrenheit. But the different temperature scales are relative; 20*F is twice as hot as 10*F. BUT the Celsius equivalent of 20*F is not twice as hot as the Celsius equivalent of 10*F.

The Kelvin scale is an absolute scale. This means that at 10 K there is twice as much thermodynamic activity as there is at 5 K. This property does not apply to either the Celsius or Fahrenheit scale - where the zero is arbitrary. A difference of 1 Kelvin is the same as a difference of 1 Celsius degree which is why, as an alternative scale, Celsius is preferred to Fahrenheit.

100 degrees Celsius is more than twice as warm as 100 degrees Fahrenheit.

Convert the temperature to Kelvin. Kelvin starts from absolute zero; so twice the temperature represents twice the internal energy. After doubling the temperature in Kelvin, you can convert back to Celsius if you like.

The Kelvin scale starts at a true zero; 0o K is the temperature at which there is actually no heat. Therefore, you get a true measure of heat using this system; an object at twice the temperature in kelvins is actually twice as hot. That is not true of other temperature scales such as Celsius or Fahrenheit.

-26 degrees? Actually, it's -229.835 degrees Fahrenheit or -136.575 Celsius. Absolute zero is -459.67 degrees Fahrenheit and -273.15 Celsius. Divide either one by 2 to get the twice as cold answer.

The question is the temperature at which F = 2C F = 32 + C x 1.8 Substitute for F = 2C 2C = 32 + 1.8 C 0.2 C = 32 C = 160 F = 32 + 160 x 1.8 = 32 + 288 = 320 Answer is: Celsius = 160 Fahrenheit = 320

The highest recorded temperature in Swedish history was 38 degrees Celsius or 100. 4 degrees Fahrenheit. It was recorded twice, first in 1933 in town of Ultuna and then again in 1947 in Malilla.

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.

It is exactly twice of 184 which is 368 degrees Fahrenheit.
