SI Decimal Prefixes: How Pb to PB Is Calculated
Both petabits and petabytes are SI decimal units, so every prefix step is exactly 1,000 and 1 Pb = 0.125 PB. This is the convention behind advertised link speeds and drive specifications. Because one unit counts bits and the other bytes, the factor also includes a factor of 8.
| Unit | Standard | Prefix step | 1 unit equals |
|---|---|---|---|
| Petabit (Pb) | SI decimal | 1,000 | 1.000 × 10¹⁵ bits |
| Petabyte (PB) | SI decimal | 1,000 | 8.000 × 10¹⁵ bits |

FAQs: Petabit to Petabyte Conversion
6 questions Quick answers on converting petabits to petabytes, using the same factors as the converter above.
-
How many petabytes are in 1 petabit?
1 Pb = 0.125 PB
1 Petabit (Pb) equals 0.125 Petabytes using the SI decimal standard.
-
How many petabits are in 1 petabyte?
1 PB = 8 Pb
1 Petabyte (PB) equals 8 Petabits.
-
How do I convert petabits to petabytes?
Pb × 0.125 = PB
Multiply the petabit value by 0.125 to get petabytes. For example, 10 Pb = 1.25 PB. To convert back (vice versa), multiply petabytes by 8.
-
Is a petabit bigger than a petabyte?
PB is 8× larger than Pb
No. 1 Pb = 0.125 PB, so the petabyte is larger — 1 PB = 8 Pb.
-
Does Pb to PB use SI decimal or binary prefixes?
Base 10 (SI): 1,000 per step
Both petabits and petabytes are SI decimal (base 10) units, so each prefix step is exactly 1,000, giving 1 Pb = 0.125 PB. Because one unit counts bits and the other bytes, the factor also includes a factor of 8. The binary (IEC) versions count in base 2 steps of 1,024 instead.
-
What is Petabit (Pb) commonly used for?
Common uses of the petabit (Pb) include: Internet exchange points, submarine cables, global network traffic.
