How to Convert Megabytes to Megabits

To convert megabytes to megabits, multiply by 8 then adjust for scale. This converts byte-based storage measurements to bit-based units. See also: Megabits to MB.

MB is a byte-based unit used for measuring file sizes and storage capacity. You might also need: how many Eb in Megabytes.

Mb is a bit-based unit—multiply bytes by 8 to get bits. See also: how many Megabits in a B.

1 MB = 8 Mb (using SI decimal standard) — which means there are 8megabits in every megabyte.

MB to Mb Conversion Formula

// Convert MB to Mb

Mb = MB × 8

// Reverse: Convert Mb to MB

MB = Mb × 0.125

MB to Mb Conversion Examples

100 MB = 800 Mb

256 MB = 2,048 Mb

500 MB = 4,000 Mb

1,000 MB = 8,000 Mb

2,048 MB = 16,384 Mb

What Is a Megabyte?

A megabyte is 1,000 kilobytes or 1,000,000 bytes using the SI decimal standard. Learn more: calculate B to GB.

The megabyte is a SI decimal unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Use our PB/s to KiB/s conversion rate.

Common uses: MP3 files, high-resolution images, short video clips, software installers Use our converting Megabytes to Nibbles.

1 MB = 8 × 10⁶ bits = 1 × 10⁶ bytes.

The megabyte can be abbreviated as MB; for example, 1 megabyte can be written as 1 MB.
