Depends on the range that we're talking about. Stellar population and density studies of the Milky Way Galaxy puts the figure at around 150 billion. Our nearest extra-galactic neighbour, the Andromeda Galaxy, is estimated to harbour 200-250 billion stars.
The normal adult human eye has a visual magnitude limit of about 6.5 which means that without optical aid we can see less than 50,000 stars in the night sky in all. At any one time that figure drops to between 2,000 - 3,000.

Stars are not scattered randomly through space, they are gathered together into vast groups known as galaxies. The Sun belongs to a galaxy called the Milky Way. Astronomers estimate there are about 100 thousand million stars in the Milky Way alone. Outside that, there are millions upon millions of other galaxies also!

One study a few years ago estimated 7 x 10^22 in the *visible* universe.

According to the BBC documentary "SPACE" there is 1 million stars for every grain of sand on planet Earth.

An infinite/uncountable number.
Basically the common assumption it that, as space is ever expanding, that there is an infinite number of stars out there. However, I would assume that there is a finite amount of matter to make them from - but who knows.

It is said that there are more stars than there are grains of sand on all the beaches of the world.
How they know that I have no idea!

Why don't you count them?
If you do 2 hours per night it should take you the rest of your life.

There are as many stars as there are grains of sand

to big of a number to express. it would look something like this
1 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000
all those zeros don't really do much for the human mind. Its just too big to truely comprehend
this is an eye opening video that directly answers your question.
