Yottabit (Yb)

The yottabit is a multiple of the unit bit for digital information or computer storage. The prefix yotta (symbol Y) is defined in the International System of Units (SI) as a multiplier of 1024 (1 septillion, short scale), and therefore 1 yottabit = 1024 bits = 1000000000000000000000000 bits = 1000 zettabits. The yottabit has the unit symbol Ybit or Yb. The yottabit is closely related to the yobibit, a unit multiple derived from the binary prefix yobi of the same order of magnitude, which is equal to 280 bits = 1208925819614629174706176 bits, or approximately 21% larger than the yottabit.

Yottabyte (YB)

Abbreviated as YB, a yottabyte is equal to 1,208,925,819,614,629,174,706,176 (280) bits, or 1,000,000,000,000,000,000,000,000 (1024) bytes and is the largest recognized value used with storage. The yottabyte is a multiple of the unit byte for digital information. The prefix yotta indicates multiplication by the eighth power of 1000 or 1024 in the International System of Units(SI), and therefore one yottabyte is one septillion (one long scale quadrillion) bytes. The unit symbol for the yottabyte is YB. 1 YB = 10008 bytes = 1024 bytes = 1000000000000000000000000 bytes = 1000 zettabytes = 1 trillion terabytes A related unit, the yobibyte (YiB), using a binary prefix, is equal to 10248 bytes (approximately 1.209 YB).
