Diameter of the known Universe?

My nephew has been asking me difficult astronomy questions,to which I did not know the answers. So I decided to ask the mighty Google, now I still have'nt an answer to this question - what is the diameter of the visible universe. Some sources quote about 28 billion light years and others around 150 bly. Does anyone know the correct answer please?
