Yottabit
Multiples of bits  


 

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 10^{24} (1 septillion, short scale),^{[1]} and therefore
 1 yottabit = 10^{24}bits = 1000000000000000000000000bits = 1000 zettabits.^{[2]}
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,^{[3]} which is equal to 2^{80}bits = 1208925819614629174706176bits, or approximately 21% larger than the yottabit.
