SI Decimal Prefixes: How GB to Gb Is Calculated
Both gigabytes and gigabits are SI decimal units, so every prefix step is exactly 1,000 and 1 GB = 8 Gb. 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 |
|---|---|---|---|
| Gigabyte (GB) | SI decimal | 1,000 | 8,000,000,000 bits |
| Gigabit (Gb) | SI decimal | 1,000 | 1,000,000,000 bits |

-
How many gigabits are in 1 gigabyte?
1 GB = 8 Gb
1 Gigabyte (GB) equals 8 Gigabits using the SI decimal standard.
-
How many gigabytes are in 1 gigabit?
1 Gb = 0.125 GB
1 Gigabit (Gb) equals 0.125 Gigabytes.
-
How do I convert gigabytes to gigabits?
GB × 8 = Gb
Multiply the gigabyte value by 8 to get gigabits. For example, 10 GB = 80 Gb. To convert back (vice versa), multiply gigabits by 0.125.
-
Is a gigabyte bigger than a gigabit?
GB is 8× larger than Gb
Yes. 1 GB = 8 Gb, so the gigabyte is the larger data storage unit.
-
Does GB to Gb use SI decimal or binary prefixes?
Base 10 (SI): 1,000 per step
Both gigabytes and gigabits are SI decimal (base 10) units, so each prefix step is exactly 1,000, giving 1 GB = 8 Gb. 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 Gigabyte (GB) commonly used for?
Common uses of the gigabyte (GB) include: Movies, video games, smartphone storage, USB drives, cloud storage plans.
