Petabit to bytes Conversion
1 petabit (Pbit) is equal to 125000000000000 bytes (B).
1 Pbit = 125000000000000 B
or
1 B = 0.000000000000008 Pbit
Formula
To convert a digital storage from petabit (Pbit) to bytes (B), multiply the digital storage in petabit by 125000000000000
d(B) = d(Pbit) × 125000000000000
Examples:
Convert 1 petabit to bytes:
d(B) = 1Pbit × 125000000000000 = 125000000000000 B

Frequently asked questions
How do I convert petabit to bytes?
Multiply the value in petabit by 125000000000000 to get the result in bytes. For example, 5 Pbit × 125000000000000 = 6.25e14 B.
How many bytes are in 1 petabit?
1 petabit (Pbit) is equal to 1.25e14 bytes (B).
How do I convert bytes back to petabit?
Use the inverse operation: divide the value in bytes by 125000000000000 to get the result in petabit.
How accurate is the petabit to bytes conversion?
The converter multiplies by the conversion factor 125000000000000 and rounds the result to 9 decimal places by default. You can increase or reduce the precision with the digits option on this page.
