You need some kind of atmosphere to make the thermometer work.

About 2.7 degrees Kelvin. Right after the Big Bang, the universe was extremely hot. After 13 or 14 billion years, it's now cooled down to a nice 2.7 degrees. The leftover radiation from the Big Bang that gives space this temperature is called the Cosmic Microwave Background.
Interesting stuff.

The temperature of space is about 2..5 Kelvin.
Kevin temperature reading begin at absolute zero
So space has a temperature of about 2.5 degrees above absolute zero. Absolute has never been attained as far as far as I know (my theory if absolute zero were attained in the Universe then light and matter would cease to exist. Don't worry if this is true it will not happen for many billions of years.

Empty space itself cannot have a temperature, unless you mean some
abstruse question about quantum vacuums.
However, if you put a physical object into space, it will reach a
temperature that depends on how efficiently it absorbs and emits
radiation and on what heating sources are nearby. For example, an
object that both absorbs and emits perfectly, put at the Earth's
distance from the Sun, will reach a temperature of about 280 K or 7 C.
If it is shielded from the Sun but exposed to interplanetary and
interstellar radiation, it reaches about 5 K. If it were far from all
stars and galaxies, it would come into equilibrium with the microwave
background at about 2.7 K.
One thing I do know for sure.... in space no one can hear you scream as you freeze to death.

If you take the total energy content of space and divide it by boltzman's constant you would obtain the total temperature of space. If you want to calculate the temperature density of space ;you simply divide it ty the total volume of space.
If you measure the temperature per unit volume and work backwarks you can calculate the diameter of the present universe.

The space between your ears? About 98.6 degrees. Near the sun? Really hot.

I think it depends on wether or not you're in the shade or the light of the sun.
I want to say that, in general, space is cold.

A Yahoo Search: temperature in space
will get your answer.
Good luck.

That depends.
Near a star it can get really hot (millions of degrees) and out in the cold interstellar regions, far from any star it gets really cold. (Like 1 Kelvin, that's minus 240 C, cold enough to turn hydrogen into a liquid.)

i believe its about 2 or 3 degrees above absolute zero . unless you get close to a star .

There is no one set temperature. Depends on how close you are to the sun, whether you're in the shadow of something, etc etc.
