SI Decimal Prefixes: How Mb to MB Is Calculated

Both megabits and megabytes are SI decimal units, so every prefix step is exactly 1,000 and 1 Mb = 0.125 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.

Mb and MB: standard, prefix step and bits
Unit Standard Prefix step 1 unit equals
Megabit (Mb) SI decimal 1,000 1,000,000 bits
Megabyte (MB) SI decimal 1,000 8,000,000 bits

FAQs: Megabit to Megabyte Conversion

6 questions Quick answers on converting megabits to megabytes, using the same factors as the converter above.

  1. How many megabytes are in 1 megabit?

    1 Mb = 0.125 MB

    1 Megabit (Mb) equals 0.125 Megabytes using the SI decimal standard.

  2. How many megabits are in 1 megabyte?

    1 MB = 8 Mb

    1 Megabyte (MB) equals 8 Megabits.

  3. How do I convert megabits to megabytes?

    Mb × 0.125 = MB

    Multiply the megabit value by 0.125 to get megabytes. For example, 10 Mb = 1.25 MB. To convert back (vice versa), multiply megabytes by 8.

  4. Is a megabit bigger than a megabyte?

    MB is 8× larger than Mb

    No. 1 Mb = 0.125 MB, so the megabyte is larger — 1 MB = 8 Mb.

  5. Does Mb to MB use SI decimal or binary prefixes?

    Base 10 (SI): 1,000 per step

    Both megabits and megabytes are SI decimal (base 10) units, so each prefix step is exactly 1,000, giving 1 Mb = 0.125 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.

  6. What is Megabit (Mb) commonly used for?

    Common uses of the megabit (Mb) include: Internet speeds (Mbps), video streaming bitrates, network bandwidth.
