How do I convert TB to PB?
For this pair, use value × 0.001. A quick benchmark is 15 TB = 0.015 PB, which can help you check whether the result is in the expected range.

Terabyte (TB) is the starting unit on this page for a digital storage conversion.
Terabyte is part of the measurement language used in hard drives, SSDs, backups, cloud storage, and media archives.
TB values are converted when large decimal storage values but the final answer needs to be shown in a different unit.
Petabyte (PB) is the result unit produced by this TB to PB conversion.
Petabyte remains common in Petabyte appears in measurement references where PB is the expected label.
PB results are useful for working with values that are already written in PB, especially when converted data sizes are used in upload limits, storage planning, device comparisons, and download estimates.
Mathematically, petabyte (PB) = terabyte (TB) converted with the formula below.
1 TB = 0.001 PB
1 PB = 1,000 TB
Formula: value × 0.001
Example: 15 TB = 0.015 PB
Precision note: Keep enough decimal places to support your actual use. Check whether a product, operating system, or file tool is using decimal or binary units before comparing values.
1 TB = 0.001 PB
1 PB = 1,000 TB
| Terabyte [TB] | Petabyte [PB] |

| 0.01 TB | 0.00001 PB |
| 0.1 TB | 0.0001 PB |
| 1 TB | 0.001 PB |
| 2 TB | 0.002 PB |
| 5 TB | 0.005 PB |
| 10 TB | 0.01 PB |
| 20 TB | 0.02 PB |
| 50 TB | 0.05 PB |
| 100 TB | 0.1 PB |
Rounding depends on what the converted value is for. A casual estimate can be rounded for readability, while values used for file sizes and upload limits or storage plans and device capacity may need more decimal places.
A common mistake is assuming KB and KiB, MB and MiB, or GB and GiB always mean the same thing. For this pair, TB and TiB differences become noticeable at large capacities Keep the PB label attached to the number so the value is not misread
When reading the result in PB, remember that keep the pb label attached to the number so the value is not misread. If another source gives a different PB value, compare the number of decimal places first. If the difference is large, check the starting value, selected units, and direction.
For this pair, use value × 0.001. A quick benchmark is 15 TB = 0.015 PB, which can help you check whether the result is in the expected range.
It is the reverse direction. This page starts with TB and returns PB; the reverse starts with PB and returns TB.
Because Petabyte is the larger unit in this pair, the converted number is smaller than the starting TB value. The relationship is 1 TB = 0.001 PB.
