The pebibit is a multiple of the bit, a unit of digital information storage, prefixed by the standards-based multiplier pebi (symbol Pi), a binary prefix meaning 250. The unit symbol of the pebibit is Pibit. 1 pebibit = 250 bits = 1 125 899 906 842 624 bits = 1024 tebibits.
The petabyte is a multiple of the unit byte for digital information. The prefix peta indicates the fifth power of 1000 and means 1015 in the International System of Units (SI), and therefore 1 petabyte is one quadrillion (short scale) bytes, or 1 billiard (long scale) bytes or 1000 terabyte, or 1 000 000 gigabytes . The unit symbol for the petabyte is PB.
