A petabyte is 2 to the 50th power, or 1,125,899,906,842,624 bytes. However, petabytes are often estimated as 10 to the 15th power, or 1,000,000,000,000,000 bytes. To avoid ambiguity, the exact calculation is often referred to as a pebibyte instead of a petabyte, though both definitions are commonly accepted.
