Quinquadecillion

According to present figures, all the matter in existence, in our own and other universes, weighs some 20,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 metric tons, or a little more in English tons. There is a simpler way to write it in figures, but the newspaper linotype has not the necessary type faces. In words, it is twenty quinquadecillion tons.

For example, computronium is a hypothetical substrate that is calculated as the densest and most efficient computing material allowed by the laws of physics. Physicist Seth Lloyd calculates that such a mythical material could compute on the order of 5 x 10^50 (500 quinquadecillion) calculations per second.
