SI Decimal Prefixes: How MB to Gb Is Calculated
Both megabytes and gigabits are SI decimal units, so every prefix step is exactly 1,000 and 1 MB = 0.008 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 |
|---|---|---|---|
| Megabyte (MB) | SI decimal | 1,000 | 8,000,000 bits |
| Gigabit (Gb) | SI decimal | 1,000 | 1,000,000,000 bits |

FAQs: Megabyte to Gigabit Conversion
6 questions Quick answers on converting megabytes to gigabits, using the same factors as the converter above.
-
How many gigabits are in 1 megabyte?
1 MB = 0.008 Gb
1 Megabyte (MB) equals 0.008 Gigabits using the SI decimal standard.
-
How many megabytes are in 1 gigabit?
1 Gb = 125 MB
1 Gigabit (Gb) equals 125 Megabytes.
-
How do I convert megabytes to gigabits?
MB × 0.008 = Gb
Multiply the megabyte value by 0.008 to get gigabits. For example, 10 MB = 0.08 Gb. To convert back (vice versa), multiply gigabits by 125.
-
Is a megabyte bigger than a gigabit?
Gb is 125× larger than MB
No. 1 MB = 0.008 Gb, so the gigabit is larger — 1 Gb = 125 MB.
-
Does MB to Gb use SI decimal or binary prefixes?
Base 10 (SI): 1,000 per step
Both megabytes and gigabits are SI decimal (base 10) units, so each prefix step is exactly 1,000, giving 1 MB = 0.008 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 Megabyte (MB) commonly used for?
Common uses of the megabyte (MB) include: MP3 files, high-resolution images, short video clips, software installers.
