Petabytes to petabit Conversion
1 petabytes (PB) is equal to 8 petabit (Pbit).
1 PB = 8 Pbit
or
1 Pbit = 0.125 PB
Formula
To convert a digital storage from petabytes (PB) to petabit (Pbit), multiply the digital storage in petabytes by 8
d(Pbit) = d(PB) × 8
Examples:
Convert 512 petabytes to petabit:
d(Pbit) = 512PB × 8 = 4096 Pbit
