How do I convert Gb to TB?
For this pair, use value × 0.000125. A quick benchmark is 15 Gb = 0.001875 TB, which can help you check whether the result is in the expected range.
Convert Gigabit (Gb) to Terabyte (TB) instantly.

Gigabit (Gb) is the starting unit on this page for a digital storage conversion.
Gigabit is part of the measurement language used in Gigabit appears in measurement references where Gb is the expected label.
Gb values are converted when working with values that are already written in Gb but the final answer needs to be shown in a different unit.
Terabyte (TB) is the result unit produced by this Gb to TB conversion.
Terabyte remains common in hard drives, SSDs, backups, cloud storage, and media archives.
TB results are useful for large decimal storage values, especially when converted data sizes are used in upload limits, storage planning, device comparisons, and download estimates.
Mathematically, terabyte (TB) = gigabit (Gb) converted with the formula below.
1 Gb = 0.000125 TB
1 TB = 8,000 Gb
Formula: value × 0.000125
Example: 15 Gb = 0.001875 TB
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 Gb = 0.000125 TB
1 TB = 8,000 Gb
| Gigabit [Gb] | Terabyte [TB] |
|---|---|
| 0.01 Gb | 0.000001 TB |
| 0.1 Gb | 0.000013 TB |
| 1 Gb | 0.000125 TB |
| 2 Gb | 0.00025 TB |
| 5 Gb | 0.000625 TB |
| 10 Gb | 0.00125 TB |
| 20 Gb | 0.0025 TB |
| 50 Gb | 0.00625 TB |
| 100 Gb | 0.0125 TB |
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, Keep the Gb label attached to the number so the value is not misread TB and TiB differences become noticeable at large capacities
When reading the result in TB, remember that tb and tib differences become noticeable at large capacities. If another source gives a different TB 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 × 0.000125. A quick benchmark is 15 Gb = 0.001875 TB, which can help you check whether the result is in the expected range.
It is the reverse direction. This page starts with Gb and returns TB; the reverse starts with TB and returns Gb.
Because Terabyte is the larger unit in this pair, the converted number is smaller than the starting Gb value. The relationship is 1 Gb = 0.000125 TB.
