To convert gigabits to megabytes, divide by 8 then adjust for scale. Since 1 byte = 8 bits, this conversion translates bit-based measurements to the byte-based units used for storage capacity.
Gb measures data in bits—commonly used for memory addressing and low-level data specifications.
MB measures data in bytes—the standard unit for file sizes, storage capacity, and what you see in file explorers.
1 Gb = 125 MB (using SI decimal standard) — which means there are 125megabytes in every gigabit.
Gb to MB conversion rate: 1 gigabit equals 125megabytes — the standard gigabit to megabyte data storage conversion used by this calculator.

SI Decimal Prefixes: How Gb to MB Is Calculated
Both gigabits and megabytes are SI decimal units, so every prefix step is exactly 1,000 and 1 Gb = 125 MB. 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 |
|---|---|---|---|
| Gigabit (Gb) | SI decimal | 1,000 | 1,000,000,000 bits |
| Megabyte (MB) | SI decimal | 1,000 | 8,000,000 bits |

FAQs: Gigabit to Megabyte Conversion
6 questions Quick answers on converting gigabits to megabytes, using the same factors as the converter above.
-
How many megabytes are in 1 gigabit?
1 Gb = 125 MB
1 Gigabit (Gb) equals 125 Megabytes using the SI decimal standard.
-
How many gigabits are in 1 megabyte?
1 MB = 0.008 Gb
1 Megabyte (MB) equals 0.008 Gigabits.
-
How do I convert gigabits to megabytes?
Gb × 125 = MB
Multiply the gigabit value by 125 to get megabytes. For example, 10 Gb = 1,250 MB. To convert back (vice versa), multiply megabytes by 0.008.
-
Is a gigabit bigger than a megabyte?
Gb is 125× larger than MB
Yes. 1 Gb = 125 MB, so the gigabit is the larger data storage unit.
-
Does Gb to MB use SI decimal or binary prefixes?
Base 10 (SI): 1,000 per step
Both gigabits and megabytes are SI decimal (base 10) units, so each prefix step is exactly 1,000, giving 1 Gb = 125 MB. 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 Gigabit (Gb) commonly used for?
Common uses of the gigabit (Gb) include: Fiber internet speeds, enterprise networking, 10GbE connections.
