There is no quantifiable way to measure knowledge. The closest way that humanity has developed is the "IQ". However, this does not necessarily measure knowledge as much as it measures a capacity to learn. There is no "I possess exactly 12000 TB of knowledge in my head right now". So, the only true answer to this question is that not even you know how much knowledge you possess.
