The petabyte is a multiple of the unit byte for digital information. The prefix peta indicates the fifth power of 1000 and means 10 in the International System of Units (SI), and therefore 1 petabyte is one quadrillion (short scale) bytes, or 1 billiard (long scale) bytes. The unit symbol for the petabyte is PB.
1 PB = 1000000000000000B = 10bytes = 1000terabytes.
A related unit, the pebibyte (PiB), using a binary prefix, is equal to 1024 bytes, which is more than 12% greater (2 bytes = 1125899906842624bytes).
Nothing to shpw find your own answer or create one hahahahhaha......AN0NYM0US H3R3
