Petabit to bits Conversion
1 petabit (Pbit) is equal to 1000000000000000 bits (bit).
1 Pbit = 1000000000000000 bit
or
1 bit = 0.000000000000001 Pbit
Formula
To convert a digital storage from petabit (Pbit) to bits (bit), multiply the digital storage in petabit by 1000000000000000
d(bit) = d(Pbit) × 1000000000000000
Examples:
Convert 1 petabit to bits:
d(bit) = 1Pbit × 1000000000000000 = 1000000000000000 bit

Frequently asked questions
How do I convert petabit to bits?
Multiply the value in petabit by 1000000000000000 to get the result in bits. For example, 5 Pbit × 1000000000000000 = 5e15 bit.
How many bits are in 1 petabit?
1 petabit (Pbit) is equal to 1e15 bits (bit).
How do I convert bits back to petabit?
Use the inverse operation: divide the value in bits by 1000000000000000 to get the result in petabit.
How accurate is the petabit to bits conversion?
The converter multiplies by the conversion factor 1000000000000000 and rounds the result to 9 decimal places by default. You can increase or reduce the precision with the digits option on this page.
