Approximately 3.6 Kelvin. Now don't quote me, I am just estimating. It may even be 4.244567 Kelvin, but a small indifference.

It's a good trick question. But we have not ever reached a temperature as cold as that. If we consider that 0 C' = 273 K', if we were to extract more heat to get to a temperature twice a cold, we would have to extract 273 time 2 measured in kelvin that is not possible since the lowest K temp is defined a 0 K' . There are no negative Kelvin temperatures.

Oddly worded question!
The lowest temperature you can get is Absolute zero. Which, if i remember correctly, is about -273DegC. (or Zero on the Kelvin scale) No temperature exists lower than this.
To find out what is twice as cold than zero degrees - convert 0DegC into DegK then double it.
Sure theres a web site that will help you with the conversion but i cant be bothered looking. Happy googling

You should be more specific. If you mean zero degrees Celsius, and by "twice as colder" you mean half the amount of thermal energy, then you could say that zero degrees Celsius is equal to 273.15 degrees Kelvin, in which case half that would be 136.575 degrees Kelvin, or -136.575 degrees Celsius. The Kelvin scale is the counterpart to the Celsius scale, with the same increments, but starting out at absolute zero (0 Kelvin, -273.15 Celsius), the point at which thermal and kinetic energy is zero.

That depends on which temperature scale you start with or which temperature you reached zero relative to.
0 degrees Kelvan is absolute zero. There is no "twice as cold."

"coldness" is not really a scientifically measurable concept, but hotness is defined. If you were to ask what is half as hot as zero degrees celcius, then the answer would be -136.5C. This is because -273C is the least hot it is possible to get , and 136.5 is halfway between 0 and -273.
-237C is equivalent (almost) to 0 degrees Kelvin... otherwise known as absolute zero.

The coldest temp ever out there that is colder than -0's is absolute zero. It is the point where all molicules stop dead. Nothing survives that temp ever.

People are wrong when they say there is nothing colder than 0 Kelvin.
I forgot to pick up the shopping last night, you should have sensed the tempereature in our house when wify got home - that was cold !

Sub zero, or -273 Celcius, or 0 Kelvin.
