They are very different. Zero degrees Kelvin is sometimes called absolute zero; nothing can get any colder than that. In comparison, zero degrees Fahrenheit is scorching hot. The degrees on those scales represent different increments of heat as well. The Kelvin scale is based on the Celsius scale; degrees on the two scales represent the same increments of heat.

On the Fahrenheit scale, the freezing point of water is 32 degrees and the boiling point of water is 212 degrees. Zero degrees Fahrenheit is colder than freezing, but it is not unbearable for properly clothed people. In Celsius, water freezes at zero degrees and boils at 100 degrees. Minus 459.67 degrees F is just about the same as zero degrees Kelvin, absolute zero. This is unimaginably cold.

You can think of the Kelvin scale as a ratio scale, and the Fahrenheit and Celsius scales as ordinal scales. K is a ratio scale because zero represents the absolute absence of heat and because degrees are equal increments of heat. So you CANconclude that an object at 500 degrees K is twice as hot as an object at 250 degrees K. You cannot conclude that an object at 212 degrees F is twice as hot as an object at 106 degrees F, because the zero point of that scale doesn't come close to representing the absolute absence of heat. F and C scales are still extremely useful because they conveniently measure temperatures within a range corresponding to our general experience of the world.

How cold is zero degrees kelvin?

Zero degrees Celsius is about the same as 273 Kelvin. Zero degrees Kelvin is a temperature that has yet to be reached in the lab, or anywhere in the known universe because at zero Kelvin mass ceases to have volume. 0 Kelvin, although only theoretical, is the lowest temperature possible, therefore zero Kelvin is much, much colder.
