Answer:

#3K# is #-270^@C#, just #3# degrees above absolute zero

Explanation:

#3K# is one hundredth of room temperature on the Kelvin scale, which represents absolute temperatures.

It is the background temperature of the universe. There is at least one place that is naturally colder - the Boomerang Nebula. Gas has been moving outwards from the Boomerang nebula for about #1500# years, resulting in cooling to about #1K# - just one degree above absolute zero.
