A kilobit is 1,000 bits. Often used for slower network connections and legacy data rates.
View the kilobit data unit pageHow to Convert Megabytes to Kilobits
To convert megabytes to kilobits, multiply by 8 then adjust for scale. This converts byte-based storage measurements to bit-based units.
MB is a byte-based unit used for measuring file sizes and storage capacity.
Kb is a bit-based unit—multiply bytes by 8 to get bits.
1 MB = 8,000 Kb (using SI decimal standard) — which means there are 8,000kilobits in every megabyte.
MB to Kb conversion rate: 1 megabyte equals 8,000kilobits — the standard megabyte to kilobit data storage conversion used by this calculator.

SI Decimal Prefixes: How MB to Kb Is Calculated
Both megabytes and kilobits are SI decimal units, so every prefix step is exactly 1,000 and 1 MB = 8,000 Kb. 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 |
| Kilobit (Kb) | SI decimal | 1,000 | 1,000 bits |

FAQs: Megabyte to Kilobit Conversion
6 questions Quick answers on converting megabytes to kilobits, using the same factors as the converter above.
-
How many kilobits are in 1 megabyte?
1 MB = 8,000 Kb
1 Megabyte (MB) equals 8,000 Kilobits using the SI decimal standard.
-
How many megabytes are in 1 kilobit?
1 Kb = 0.000125 MB
1 Kilobit (Kb) equals 0.000125 Megabytes.
-
How do I convert megabytes to kilobits?
MB × 8,000 = Kb
Multiply the megabyte value by 8,000 to get kilobits. For example, 10 MB = 80,000 Kb. To convert back (vice versa), multiply kilobits by 0.000125.
-
Is a megabyte bigger than a kilobit?
MB is 8,000× larger than Kb
Yes. 1 MB = 8,000 Kb, so the megabyte is the larger data storage unit.
-
Does MB to Kb use SI decimal or binary prefixes?
Base 10 (SI): 1,000 per step
Both megabytes and kilobits are SI decimal (base 10) units, so each prefix step is exactly 1,000, giving 1 MB = 8,000 Kb. 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.
