To convert tebibytes (binary/IEC) to petabytes (decimal/SI), multiply by 0.001099511628. Binary units use base 1,024, while decimal units use base 1,000—this creates small differences that accumulate at larger scales.
TiB is a binary (IEC) unit where 1 TiB = 1,024 of the smaller unit. Operating systems like Windows typically display storage using binary calculations.
PB is a decimal (SI) unit where 1 PB = 1,000 of the smaller unit. Storage manufacturers use decimal units, which is why a "1 TB" drive shows less in Windows. Related: Tebibytes to Exabytes.

SI Decimal vs Binary: Why TiB to PB Is Not a Round Number
Petabyte (PB) is an SI decimal unit: each prefix step multiplies by 1,000, so 1 PB = 8.000 × 10¹⁵ bits. Tebibyte (TiB) is an IEC binary unit: each prefix step multiplies by 1,024, so 1 TiB = 8,796,093,022,208 bits. Dividing one by the other gives 0.001099511628, which is why TiB to PB is not a round number.
| Unit | Standard | Prefix step | 1 unit equals |
|---|---|---|---|
| Tebibyte (TiB) | Binary (IEC) | 1,024 | 8,796,093,022,208 bits |
| Petabyte (PB) | SI decimal | 1,000 | 8.000 × 10¹⁵ bits |
To compare like with like, use TB to PB for SI decimal or TiB to PiB for binary (IEC).
FAQs: Tebibyte to Petabyte Conversion
6 questions Quick answers on converting tebibytes to petabytes, using the same factors as the converter above.
-
How many petabytes are in 1 tebibyte?
1 TiB = 0.001099511628 PB
1 Tebibyte (TiB) equals 0.001099511628 Petabytes using the SI decimal standard.
-
How many tebibytes are in 1 petabyte?
1 PB = 909.4947017729 TiB
1 Petabyte (PB) equals 909.4947017729 Tebibytes.
-
How do I convert tebibytes to petabytes?
TiB × 0.001099511628 = PB
Multiply the tebibyte value by 0.001099511628 to get petabytes. For example, 10 TiB = 0.010995116278 PB. To convert back (vice versa), multiply petabytes by 909.4947017729.
-
Is a tebibyte bigger than a petabyte?
PB is 909.4947017729× larger than TiB
No. 1 TiB = 0.001099511628 PB, so the petabyte is larger — 1 PB = 909.4947017729 TiB.
-
Why is TiB to PB not a round number?
1 PB = 8.000 × 10¹⁵ bits · 1 TiB = 8,796,093,022,208 bits
Petabyte (PB) is an SI decimal (base 10) unit and Tebibyte (TiB) is a binary IEC (base 2) unit, so their prefixes step by 1,000 and 1,024. That is why 1 TiB = 0.001099511628 PB instead of a round number.
-
What is Tebibyte (TiB) commonly used for?
Common uses of the tebibyte (TiB) include: OS-reported drive capacity, NAS actual storage, enterprise storage systems.
